You're here because you're setting up a Blackberry on OS10 for T-Mobile and none of your MMS text messages are sending. Here is how you fix that. T-Mobile seems to only setup the APN for you by default, but they forget to configure the final step (2.6 below), which actually makes it work.

- Settings
- Networks and Connections
- Mobile Network
- APN
- Ensure the APN is:
fast.t-mobile.com - Make sure
usernameandpasswordare empty.
The extra part in this step is adding the "Multimedia Messaging Service Center" (MMSC). The MMSC is basically just a relay to the main MMS storage.
- BBHub
- Settings (The triple dot, not the burger)
- Text Messages
- Advanced
- Ensure the APN is:
fast.t-mobile.com - Ensure the MMSC URL is:
http://mms.msg.eng.t-mobile.com/mms/wapenc
I was initially worried about the MMSC URL being http instead of https. It only works as http in the Text Messaging settings for Blackberry, so don't waste your time trying https. In a web browser, T-Mobile does a 302 redirect to an https version of the url.

Off it goes into BigIP, their MMS store with some validation kicking in:
