Dmitry Sumin: What to Do About Flash Calls, the New SMS Replacement

Why are flash calls on the rise and how do operators handle them to maximize revenue?

Chances are you’ve received several flash calls this week when registering for a new app or verifying a transaction. Flash calls are almost instantly dropped calls that deliver one-time passcodes to users, verifying their phone numbers and actions. Many prominent apps and companies, such as Viber, Telegram, WhatsApp, and TikTok, use flash calls as a cheaper, faster, and more user-friendly alternative to application-to-person SMS.

With the flash call volume expected to increase 25-fold from 2022 to 2026, from five to 130 billion, it’s no wonder they’re a hot topic in the telecom industry.

But what’s the problem, you may ask?

The problem is that there is currently no way for operators to bill zero-duration calls. This means operators don’t make any termination revenue from flash calls, which overload networks. What’s more, operators lose SMS termination revenues as businesses switch to flash calls. SMS business messaging accounts for up to five percent of total operator-billed revenue in 2021, so you can see the scale of potential revenue losses for operators. 

In this article, I’ll discuss why flash calls are on the rise, why it’s difficult to detect and monetize them, and what operators can do about this.

Why are flash calls overtaking SMS passcodes?

Previously, application-to-person SMS was a popular way to deliver one-time passwords. But enterprises and communication service providers are increasingly switching to flash calls because they have several disruptive advantages over SMS.

First and foremost, flash calls are considerably cheaper than SMS, sometimes costing up to eight times less. Cost of delivery is, of course, a prime concern for apps and enterprises.

Second, flash calls ensure smooth user interaction, which boosts user satisfaction and retention. On Androids, mobile apps automatically extract flash call passcodes. This makes the two-factor authentication process fast and frictionless. In comparison, SMS passcodes require users to read the SMS and sometimes insert the code manually.

Third, on average flash calls reach users within 15 seconds, while SMS sometimes take 20 seconds or longer. The delivery speed of flash calls also improves the user experience.

The problem: Flash calls erode operators’ SMS revenues

While offering notable advantages for apps, flash call service providers, and end users, flash calls create numerous challenges for operators and transit carriers.

As we discussed before, flash calls erode operators’ SMS revenues because much of the new flash call traffic will be shifted away from current SMS business messaging. The issue is only going to become more pressing as the volume of flash calls grows.

So from the operator’s standpoint, flash calls reduce revenue, disrupt relations with interconnect partners, and overload networks. However, there is still no industry consensus on how to handle flash calls: block them like spam and fraudulent traffic or find a monetization model for this verification channel, like for application-to-person SMS.

Accurate detection of flash calls is a challenge

The first crucial step that gives operators the upper hand is accurately detecting flash calls.

This is difficult because operators have no way of discerning legitimate verification flash calls from fraud schemes that rely on drop calls, such as wangiri. The wangiri fraud scheme uses instantly dropped calls to trick users into calling back premium rate numbers. In addition, flash calls need to be distinguished from genuine missed calls placed by customers.

The problem is that even advanced AI-powered fraud management systems struggle to accurately differentiate between various zero-duration calls. The task requires AI engines to be trained on large volumes of relevant traffic coupled with analysis of hundreds of specific call parameters.

Dedicated anti-fraud solutions are the answer

There are only a few solutions on the market that are capable of accurately distinguishing flash calls from other zero-duration calls. Dedicated fraud management vendors have made progress on this difficult task.

The highest accuracy of flash call detection now available on the market is 99.92 percent. Such tools allow operators to precisely determine the ranges from which flash calls are sent. As a result, operators can make an informed decision on how to treat flash calls to maximize revenue and can proactively negotiate with flash call providers.

Flash call detection creates new opportunities

Our team estimates that flash calls make up to four percent of Tier one operators’ international voice traffic. Without accurate detection and a billing strategy, this portion of traffic overloads operators’ networks and offers no revenue. However, with proper detection flash calls offer a new business opportunity.

Now is a crucial time for operators to start implementing flash call detection into their system and capitalize on the trend.

There are a few anti-fraud solutions on the market that give operators all the necessary information to negotiate a billing agreement with a flash call provider. Once an agreement has been reached, all flash calls coming from this provider will be monetized, much like SMS.

All flash calls not covered by agreements can be blocked automatically. This will help to restore SMS revenues. Once a flash call has been blocked, subscribers will most likely receive an SMS passcode sent as a fallback.

Moreover, modern solutions don’t affect any legitimate traffic because they only block selected ranges. This also helps to prevent revenue loss.

Essentially, the choice of how to handle flash calls comes down to each operator. However, without a powerful anti-fraud solution capable of accurately detecting flash calls in real time, it’s nearly impossible to monetize flash calls effectively and develop a billing strategy.

Broadband Mapping & Data

Tom Reid: Accountability in Broadband Maps Necessary for BEAD to Achieve Mission

The sheer magnitude of the overstatements in the FCC’s map makes the challenge process untenable.

Published

on

The author of this Expert Opinion is Tom Reid, president of Reid Consulting Group.

With millions of American households stranded in the digital desert, we need to achieve accountability in broadband to make sure the Broadband Equity, Access and Deployment funding achieves its mission. The broadband gaps can be readily identified despite the air of mystery surrounding the topic.

Broadband improvements have been constrained for decades by inaccurate maps, yet the Federal Communications Commission continues to accept dramatically exaggerated availability and capacity claims from internet service providers. The cumbersome challenge process requires consumers and units of government to prove a negative — a logical fallacy.

The Reid Consulting Group and other parties, including Microsoft, have developed robust algorithms to reliably identify actual broadband availability. RCG utilizes Ookla Speedtest Intelligence data due to the large quantity of consumer-initiated tests. In Ohio, as an example, we draw on more than 16 million speed tests reflecting the lived experience from millions of households. We combine the speed test findings with FCC and Census data to deliver irrefutable identification of unserved and underserved locations.

Such methodologies offer State Broadband Leaders the opportunity to reverse the burden of proof in the BEAD program, requiring that ISPs submit concrete evidence supporting their availability and speed claims. As an example, in Ohio, RCG’s maps were accepted as proof of unserved status for the 2022 state grant program. BroadbandOhio then required ISPs to submit substantial proof in their challenge process. In other words, the ISP’s were tasked with proving a positive instead of expecting citizens to prove a negative.

ISPs and the FCC denounce crowdsourced data unless conducted under unusually restrictive conditions. The ISPs have successfully promoted unsubstantiated myths regarding the value of consumer-initiated speed tests.

Myth: Bad tests are because of poor Wi-Fi.
Reality: RCG eliminates speed tests with weak Wi-Fi and includes GPS enabled wired devices. Even first-generation Wi-Fi would saturate a 25 Megabits per second download and 3 Mbps upload connection.

Myth: Residents only subscribe to low-speed packages.
Reality: According to the National Rural Electric Cooperative Association, in areas where rural electric cooperatives offer broadband, 25 to 33 percent of rural subscribers opt for the top speed tier offered. We can clearly see this trend in areas where fiber has been deployed in recent years, as described later in this article.

Myth: People only test when there is a problem.
Reality: Network problems prompt tests, as do resolutions of problems.  RCG recommends focusing on the maximum speed test results to eliminate this “unhappy customer effect.”

Finding the truth: Broadband and the lived experience

In Ohio, RCG analyzed more than 14 million consumer-initiated speed tests over a three-year period. The data reveals a clear pattern of carrier overstatement. The stark visual contrast between the two maps is hard to ignore — and while this study is focused on Ohio, the issue remains nationwide in scope. The sheer magnitude of the overstatements makes the FCC challenge process untenable.

Figure 1: Ohio Broadband Reality vs. FCC ISP stated coverage map.

RCG utilized the “maximum speeds ever seen” at a location for generating maps and coverage figures, but we also examined the results from the average of speed test. Switching between average and maximum speeds does not change the overall picture of broadband availability. As an example, Figure 2 focuses on an area around Bolivar, Missouri. Looking at the maximum speed turns Bolivar itself a deeper green, meaning “better served,” but the rural areas around Bolivar remain predominantly red, meaning “unserved.”  The preponderance of evidence clearly demonstrates that much of the rural area around Bolivar remains unserved, even at maximum speeds.

Figure 2: Map visualization illustrating the difference between viewing average speeds in the Bolivar, Missouri area and maximum speeds documented.

When rating broadband availability in the Bolivar area at the Census block level and overlaying with ISP coverage claims at the H3 R8 level, you can see that many of the unserved and underserved areas have been reported as served to the FCC by ISPs (Figure 3).

Figure 3: Carrier overstatement small scale in Bolivar, Missouri. RCG speed map with FCC H3 R8 hexagon overlay.

Zooming out to examine the entirety of Missouri (Figure 4), the pattern of ISP overstatement becomes quite clear. According to the FCC maps, most of the state is served, whereas the analysis conducted by RCG shows that significant areas remain in need of broadband investment. As with Ohio, the scope of the overstatement in Missouri presents an unreasonable burden on the public to challenge.

Showing Progress: Change of State Analysis

Change-of-state analysis taps progressive releases of Ookla records to identify areas where broadband speeds have set new highs. This approach works not only for grant funded projects but also private investments. The area surrounding Byesville, Ohio (Figure 5) reveals a significant uptick in test volume, test locations, and speeds from 2020 to 2022. Side-by-side comparison shows a large number of “green” (served) speed test locations where there used to be only “red” (unserved) and “orange” (underserved) results. This change is a direct result of a Charter Communications Rural Digital Opportunity Fund deployment.

Figure 5: The unserved area around Byesville, Ohio before and after broadband deployment.

State Broadband Leaders can use these capabilities to document progress and identify lagging projects. Any service area will always exhibit a mix of speed test results.  Even in an area like Byesville where fiber-to-the-home has been deployed, not all the location “dots” will turn green. However, the preponderance of evidence clearly shows that a funded ISP — in this case, Charter — has made good on its commitment to expanded broadband access. ISPs can help by conducting speed tests at the time of installation from the customer’s premises and by increasing minimum packages to 100/20 Mbps or higher.

There is no mystery to solve — we know how to identify areas lacking broadband services. For many rural Americans, even their telephone services have become unreliable, still dependent on the now-decrepit copper cables built in the 1940s through 1960s. We all depend on a healthy rural economy for our food, water and energy. Let’s make the commitment to build the infrastructure needed to bring these households into the internet age — starting by bringing reality and accountability to the availability maps.

Johnny Kampis: Broadband Industry Hopeful to Get Waivers from Biden Administration Protectionist Policies

The Buy America mandate could seriously hamper the Broadband Equity, Access and Deployment program.

Published

on

The author of this Expert Opinion is Johnny Kampis, director of telecom policy for the Taxpayers Protection Alliance.

In a presidential administration rife with protectionist policies, the broadband internet industry is optimistic it will receive waivers from the Buy America” mandate that threatens to derail plans to close the digital divide.

The National Telecommunications and Information Administration is likely to announce state funding allocations for the $42.5 billion Broadband Equity, Access and Deployment program by the end of June. That is the biggest piece of the taxpayer-funded pie allocated by Congress to extend broadband infrastructure across the U.S. over the next several years.

But, as the Taxpayers Protection Alliance has reported, broadband industry leaders say the Buy America mandate could seriously hamper the effort. As part of the mandate, the Biden administration has said that at least 55 percent of the component parts of a product used in federal construction projects must be sourced domestically. That rule applies to any infrastructure project, but broadband has taken center stage recently with the BEAD funding imminent.

Because fiber-optic cables primarily used in broadband infrastructure projects include materials such as aluminum, copper, glass, plastic and steel that are primarily manufactured in other countries, under the current rules they would be forbidden. And many other important cogs in the broadband machine, such as routers and switches, are mostly made overseas. Even the left-leaning Brookings Institution noted the policy could put broadband deployments as risk.”

Fortunately, the Biden administration is softening on its Buy America policies — at least in the broadband industry. NTIA chose earlier this month to exempt several categories of equipment such as broadband routing equipment, transceivers and antennas from the domestic manufacturing requirements in the Enabling Middle Mile Infrastructure Program. The agency said that although there are public and private efforts underway to increase manufacturing capacity… industry will not be able to address shortages of the manufactured products and construction materials required for middle mile network deployment within the timeframes required.”

Broadband Breakfast pointed out in a recent article that it will take several years to ramp up production of semiconductors in the U.S. and the BEAD program has set a five-year timeline for project completion.

The estimates are that it would take at least, at a minimum, three to five years to bring a semiconductor chip plant to the U.S.,” said Pam Arluk, vice president of NCTA – The Internet & Television Association. And even though the BEAD program is going to be over several years, thats still just not enough time.”

The inherent difficulties in meeting the Buy America mandate, and the precedent now set with the middle mile program, provide optimism that waivers will likely be offered with BEAD. But that is just one of many infrastructure programs now being funded by taxpayers through federal recovery programs.

As President Joe Biden said in his State of the Union Address in February, American-made lumber, glass, drywall, fiber optic cables…on my watch, American roads, American bridges, and American highways will be made with American products.”

Washington Post columnist Fareed Zakaria pointed out that what he calls the Biden Doctrine” violates the spirit of the World Trade Organization and its framework of open trade. And another Post columnist, former Clinton administration Treasury Secretary Lawrence Summers, noted that protectionist policies tend to hurt more people than they help — giving as an example steel tariffs that aided 60,000 steel workers, but threatened the jobs of 6 million other workers in industries paying inflated prices for steel.

Strides in broadband waivers are a good sign, but the Biden administration must do more to curtail its protectionist policies as industries use economic recovery funds to build infrastructure in the coming years.

Angie Kronenberg: The FCC Must Act Now to Save the USF

While the USF remains vital in an ever-increasing connected world, it is in serious jeopardy of surviving.

Published

on

The author of this Expert Opinion is INCOMPAS President Angie Kronenberg.

Last week, the Senate Subcommittee on Communications, Media and Broadband held a hearing titled “The State of Universal Service.” The Universal Service Fund is our nation’s critical connectivity program that helps ensure that voice and broadband services are available and affordable throughout the country.

Since its creation by Congress in the 1996 Telecom Act, the USF has become a program that millions of families, community anchor institutions and small businesses rely on to get connected. It has been especially valuable for families and businesses that rely on it for work, school and telehealth at home.

The USF spends about $8.5 billion annually to help fund affordable connectivity in rural areas, low-income households, schools, libraries and rural hospitals. Today, the Federal Communications Commission is working to make high-speed broadband as ubiquitous as telephone service, and broadband is the essential communications technology the USF now supports.

While the USF remains vital in an ever-increasing connected world, it is in serious jeopardy of surviving. To fund the programs, telecom providers are required to pay a certain percentage of their interstate and international telecom revenues, known as the “contribution factor.” Typically, telecom providers collect these USF fees from their customers on their monthly bills.

However, the telecom revenues that fund the USF have declined over 60 percent in the last two decades. As a result, the contribution factor has skyrocketed from about 7 percent in 2001 to a historic high of about 30 percent today, as a higher portion of telecom revenues is needed to sustain the fund. That means certain consumers and businesses are now paying an additional 30 percent on top of their phone bills in order to fund the USF.

Telecom revenues continue to decline so rapidly because customers today rely more on broadband services and less on landline and mobile phone services, but broadband revenues do not pay into the USF. While the FCC has modernized each USF program to help support broadband service, it has not modernized its funding mechanism to require broadband services to pay into the Fund even though historically the agency has required supported services to be included in the contribution system.

Without intervention, the contribution factor is predicted to rise to 40 percent by 2025. This is unsustainable and puts the stability of the entire USF at risk. In fact, the contribution factor has become so high that it has led some groups to challenge the USF in federal court as unconstitutional, which also threatens the sustainability of the USF.

Reforming the USF funding mechanism is urgently needed and long overdue

Over 340 diverse stakeholders have come together as the USForward Coalition calling on the FCC to move forward with USF reform by expanding the contribution base to include broadband revenues. This solution is based on the recommendation in the USForward Report (that INCOMPAS helped commission), which was written by USF expert and former FCC official Carol Mattey.

The USForward Report explains that the most logical way to reform the contribution system and sustain the USF is to include broadband revenues in its funding assessment. Under this approach, the contribution factor is estimated to fall to less than 4 percent. It also means that the services that get USF support are paying into it, rather than solely relying on telecom customers, including those that have not made the switch to broadband, such as older Americans.

In fact, some members of Congress understand the urgency of reform and also want the FCC to act. The Reforming Broadband Connectivity Act, for example, is a bipartisan, bicameral bill that would require the FCC to reform the contribution system within one year.

Some question whether large tech companies should be assessed to contribute to the USF, and the short answer is “No.” Tech companies invest $120 billion each year in global internet infrastructure, and unlike broadband providers, these companies do not request or receive USF funding for these investments.

The FCC also lacks the authority to regulate tech companies and doing so would require Congress to act. This would further delay reform and expand the FCC’s regulatory authority over all online content and services — an overreach that many question as too broad since nearly every business today has an online presence and uses the internet to conduct business. Moreover, proposals to target certain tech companies risk skewing the online marketplace and competitive markets.

Some also question whether we still need the USF at all, and the short answer is “Yes.” While Congress allocated tens of billions for broadband, most of this investment is targeted for deployment, yet a significant portion of the USF programs focus on affordability. We not only have to make sure we build out our broadband networks, but also that communities can then afford to subscribe to these services.

The FCC should not wait to reform the USF. The USForward Report sets out a real plan that the FCC can and should implement. Congress should encourage the FCC to act now and save the nation’s critical connectivity program.
