Mobile Device Certification

Confident of Connecting?Imagine landing in a foreign country on a plane. As soon as you switch on your smartphone after reaching the parking position, it connects to a foreign network. What makes you confident that this works without any issues? How does your device work the same at home and abroad? COMPRION answers with the technical insight and background information. Thus, you can learn, how to make people put confidence in your solution for connecting them to any network worldwide: In a nutshell  – with the help of mobile device certification.


Perfect Understanding Between Device, (e)SIM & Network

Make mobile device, (e)SIM, and network understand each other 

Mobile device manufacturers often do not know which network operator their customers will choose. They also cannot test all (e)SIMs. Therefore, worldwide standards have been introduced to counter this problem. These standards define protocols for clear communication and thus ensure harmonized technical behavior.

Why mobile device certification?

Only if the device and the (e)SIM work together flawlessly, a successful access to a network is possible. The certification of mobile devices is therefore essential for their success. We have been working closely with standardization bodies for years and always strive to have the first and best solution on the market.


Certification for Global Market Access

Both, PTCRB and the Global Certification Forum (GCF), are industry certification bodies for telecommunications. Their product approvals open global market access for mobile devices. GCF group their lists of tests in so-called work items, for example, WI-508-NR for USIM interworking with 5G. In contrast, PTCRB uses the term requests for testing (RFT). The certification tests are executed on GCF-/PTCRB-validated test platforms (TPs).
