Here is my issue. My wife has a LG G3. My cousin has a Samsung Galaxy 5. Both are in my town and both have 4G LTE. About 2-3 weeks ago their phones changed from EDGE to 4G LTE everywhere. My HTC One M8 is stuck on EDGE. I have been on the phone 4 times with T-mobile tech support regarding this issue. They said my area is EDGE only but they are in the process of upgrading the network. They will only guarantee EDGE speeds until the upgrade is complete. I have checked my phone and APN settings and it is ready for 4G LTE. When I am in a 4G LTE area I do have it so it is not the phone. Has anyone else experienced this issue and how long did it take before you got 4G LTE?
