How do I troubleshoot MMS on a Non-AT&T Android Device?
When activating on Wing GSM (AT&T) with a Non-AT&T Android Device, you might run into some issues that prevent MMS from properly coming through.
To fix this there are two solutions:
- Make sure the APN Settings are properly set up and match the listed Settings: Wing GSM APN Settings. See here for more info.
- If all settings match and you're still having trouble with MMS we would suggest downloading a third-party text messaging app such as Textra.
This has been the solution that has worked best for most users when enabling their phone to send MMS/Picture Messages.
If you are still having trouble, please go into Textra and go to Settings > MMS Settings > Send Size, and change the setting to either No Limit or 1MB.
