AT&T  Certification is Simple

If your device uses an AT&T Approved Module take the actions below simultaneously to initiate the Network Ready process. It’s possible that your device may already be certified, and does not require network ready testing. Review this list of AT&T Certified Devices to find out if your device is already certified. We only certify devices based on 5G NR, LTE, LTE-M, and NBIoT technologies. In addition, there are a few devices listed here that you can not currently test on your own. You may find it helpful to download our checklist for AT&T Network Ready Certification as a PDF.

    • Determine How You will Identify Your Device

      Network Ready devices must comply with ONE of the following identification methods.
      Prior to network testing, you’ll need to choose the method you plan to use.

  • Order AT&T TRENDI SIMs

    The Test Requirements for Evaluating Network Ready Devices for IoT (TRENDI) verifies that your device will work efficiently on our network, is capable of receiving SMS messages, and is using the same software/firmware you use for PTCRB certification (see below). TRENDI takes approximately 48 hours, and requires that you use AT&T SIMs . You can order your AT&T SIMs for TRENDI at this link. We will mail you an ACTIVATED SIM and a DEACTIVATED SIM to use, with detailed instructions for testing. You can also view the testing instructions here.


    • If you already have AT&T SIM cards with an identifier that begins with 8901170 you may onboard your device here.


  • Get Industry Certified

    Your device must be PTCRB certified and meet AT&T’s minimum antenna performance specifications for testing. At this link, you can view the AT&T antenna performance limits.  The minimum required bands for operation on the AT&T US domestic network are LTE bands 2, 4, and 12. PTCRB certification can be obtained from any of these AT&T approved PTCRB labs. Additionally, AT&T has partnered with two PTCRB labs for exclusive tiered pricing.

Some Devices May Not Qualify for Our Simple Certification Procedures

Some Devices May Not Qualify for Our Simplest Network Ready Procedures

In some cases, becoming Network Ready requires different steps. This is true of the following device types:

  • Drones
  • Non-Windows Laptops
  • Non-Windows Tablets
  • Telematics Control Units (factory installed)
  • Devices that will use a FirstNet SIM

Additionally,  separate certification processes are required for devices using chipsets or non-approved modules. Click here and you will be guided into the correct process to get certified on these device types.
