It is an unlocked phone, and I'm also using a tmo SIM

Yes, easy to overlook, I am in the USA.

Hi,

I recently picked up a T-Mobile 6T. After trying unsuccessfully to get a bootloader unlock file, I went the brute force route described on XDA. After doing that I was able to install the latest ubuntu touch without issue.

For the most part things work. I seem to have the same shutdown issue as others do.

The bigger problem is I can only send SMS, I only get SMS if I go into airplane mode and back out. starting the TMO network back up seems to flush things out. MMS dos not work at all.

When I go look at the APNs, they are wrong, trying to edit them is a nightmare and not complete. I did find a couple of copies of apns-conf.xml and tried to fix them there but they cannot be edit or replaced even as sudo. I expect it the file system is mounted read only.

I've seen some folks have it working on other carriers, any ideas how to fix this? I expect it's an APN issue, if I could get this working I would be quite happy with a Linux phone.
