Same issue here. Bought a HTC One (M7).
everything so far works except MMS.
The only way I can get the connection set up correctly (have the radio button next to the APN name) is this:
- Name: T-Mobile
- APN: fast.t-mobile.com
- Proxy:<Not set>
- Port:<Not set>
- Username:<Not set>
- Password: <Not set>
- Server:<Not set>
- MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc
- MMS proxy:<Not set>
- MMS port:<Not set>
- MMS protocol: WAP 2.0
- MCC: 310
- MNC: 260
- Authentication type:<Not set>
- APN type:default,supl,mms *** the <Not Set> OR Internet+MMS settings don't work at all ***
But as noted, no MMS...
This BYOD thing is a joke. But i guess that's how they expect you to pay an additional $300 for a t-mobile branded phone.
BTW, the T-mobile branded Samsung Galaxy Light phone I did wasted $216 on was worthless.
