You get a gold star for being proactive and already trying those troubleshooting steps out -- thank you! Are your settings already updated to these: BYOD T-Mobile data & APN settings ? If not, let's try that to see if it keeps disconnecting. Are you having any issues making/receiving calls or is it strictly data speeds? Lastly, if you travel more than 15 miles from the location that drops you to EDGE, do you see an improvement?
Yes I made sure to verify that the APN settings are all correct.
I can make calls fine while stationary, but the signal is weak and disconnects when I am moving (on the train).
Traveled 30 miles away from my current location and it does not fix the issue.
