Global Telecom Testing (GTT) will be attending World Telemedia Marbella 2026, and we’d like to sit down with you while we’re there.
World Telemedia Marbella brings together the mobile payments, messaging, and digital content industry each year, covering everything from Direct Carrier Billing (DCB) and mobile commerce to CPaaS, fraud prevention, and mobile advertising. Last year’s edition drew nearly 700 delegates representing 277 companies from 66 countries, and this year’s event, running October 4 to 6 at the Hard Rock Hotel in Marbella, is shaping up to continue that momentum.
Fraud and fighting it sit high on this year’s agenda, alongside payments infrastructure and messaging engagement, and that combination lines up closely with the work GTT does every day. Artificially inflated traffic, grey-route SMS, and OTP delivery failures are all symptoms of the same underlying problem: telecom infrastructure that looks fine on paper but hasn’t been independently verified in the markets where it actually matters.
For an industry built on moving payments, messages, and authentication events across borders at scale, the telecom infrastructure underneath all of it rarely gets its own spotlight, even though every other part of the stack depends on it. That’s the layer GTT focuses on.
Who We’re Looking to Meet
We’re especially interested in conversations with:
- Mobile payment providers managing OTP delivery for transaction authentication across international markets
- CPaaS platforms responsible for message deliverability on behalf of enterprise customers
- Telecom operators negotiating interconnect and roaming agreements who need independent verification of real-world delivery performance
- IT operations teams at global enterprises troubleshooting recurring phone number, SMS, or IVR issues in specific markets
If any of that sounds familiar, whether you’re dealing with unexplained OTP failure rates, unverified SMS delivery claims from a carrier partner, or a phone number inventory nobody has audited in years, we’d like to hear about it.
What GTT Brings to the Table
Founded in 2007, GTT built its testing model around a simple premise: the most reliable way to verify telecom performance is to test it the way a real customer experiences it, not the way a lab simulates it. Today, that means OTP testing, SMS delivery testing, and phone number testing performed by more than 800 local, in-country testers across over 200 countries, using real handsets on real carrier networks rather than synthetic lab infrastructure. GTT’s testing programs verify more than 50,000 phone numbers and perform over 100,000 test calls annually for global enterprises, carriers, and payment platforms.
For platforms scaling into new markets, or operators trying to close the gap between contracted delivery rates and what’s actually reaching subscribers, that kind of independent, ground-level verification tends to surface issues no dashboard catches on its own.
Book Time With Us in Marbella
Stephen Levenson, GTT’s President, and Jenee Bowen, Vice President of Operations, will both be on-site throughout the event and available for meetings at our table. Whether you want to walk through a specific delivery problem, discuss testing coverage for an upcoming market launch, or just compare notes on what’s changing in the industry, we’d rather talk in person than trade emails afterward.
Schedule a meeting with GTT at World Telemedia Marbella 2026, and we’ll confirm a time that works around the conference schedule.
Not attending but want to connect anyway? Contact our team directly, and we’ll find another time to talk.
Jenee Bowen is Vice President of Operations at Global Telecom Testing, where she oversees in-country testing programs across more than 200 countries, including phone number, SMS, IVR, and OTP verification for global enterprises.
