Narrowband: Device Certification for Production

Any product utilizing the T-Mobile Narrowband network that is intended for commercialization will need to be certified by T-Mobile. As the OEM/Product Developer, you will have to provide device capability information to T-Mobile. This is a necessary step needed before you mass-manufacture your device.

Certification requirements include security certification, ‘Safe For Network’ testing, and PTCRB delta certification. T-Mobile will also onboard the device to its Device Management platform.

Fast path to certification

The quickest way to achieve certification is to utilize a module that has been pre-certified by T-Mobile. You can find a list of modules that have been certified and approved by T-Mobile here.

Required certifications and tests

  • T-Mobile module certification.
  • Product PTCRB.
  • CTIA Device Security test plan.
  • T-Mobile Device Management verification.
  • T-Mobile ‘Safe for Network’.

The entire end-to-end certification process can take up to four to six weeks and there are additional costs involved. Please work with your assigned Twilio representative or contact us at for further assistance.
