Madrid, 28-06-2022 It is a fact. New 5G technological deployments will take place in tandem with a gradual shutdown of the legacy 2G and 3G network in many geographies. . This is a challenge for different IoT models where voice communication remains essential.

Although internet calling via apps like WhatsApp is becoming increasingly common, we can´t forget that voice calls are still here. With VoLTE (Voice over Long Term Evolution) service, companies can make calls that start faster, with better voice quality, reducing background noise and without interrupting other phone functions such as receiving messages or emails.

"TGS has carried out a project to deploy and roll out VoLTE technology for IoT in a roaming environment to all global sim cards that are attached to AT&T’s network in USA"

It’s important that IoT connectivity providers can deliver the solutions needed to aide this transition to new models, and at Telefónica Global Solutions we have ensured that our services are ready to do just that for our customers. Our IoT managed connectivity service, cover any customer IoT business needs, providing control and management over IoT communications, in real-time and at any location worldwide.

Global IoT connections are expected to reach 5 billion by 2030 and the number of IoT devices is growing exponentially, making it the next digital revolution according to GSMA Intelligence.

In this sense, one of the first countries impacted is USA, due to the decision of AT&T to decommission their legacy infrastructure.As a result of this strategic move in the telco sector, some of our biggest customers are faced with the challenge to keep their existing services up and running with the minimum operational impact.

That was the case, for example, for a leader in the elevator market with presence in more than 100 countries and one of the most important global customers for Telefónica, who needed to continue offering voice calls in case of emergency from their elevators. With the 2G and 3G shutdown, VoLTE (Voice over LTE) was positioned as the main substitutive technology.


It is based on the IMS (IP Multimedia Subsystem) architectural framework and therefore provides better voice quality, reduced call establishment times and lower power consumption than older technologies..

Telefonica Global Solutions, once again responding to its customers' needs, has carried out a project to deploy and roll out VoLTE technology for IoT in a roaming environment to all global sim cards that are attached to AT&T’s network in USA.

Additionally, this implementation has opened the possibility to reach an LTE agreement with Verizon and to include it as an additional mobile operator for our global sim cards, which will greatly expand coverage for all customers using Telefónica’s IoT service.


In addition to the United States, Telefónica has begun to work on an ambitious plan of VoLTE roaming agreements with different partners worldwide to prepare our service for the next wave of 2G & 3G shutdowns in other countries.
