Help HELP! Factory Rest Note 8, 3G works but Not LTE Despite Fixing APN settings (MetroPCS+TMo)

[afroag]

Hi I reset my Note 8 because after using this thing for a year and half, with all the security updates, my GPS location would stop working mid drive or my push notifications would stop working.

I booted into recovery and factory reset my phone. Now the phone won't work with mobile data. Well it only works with mobile data when I am on a phone call and my signal switches from LTE to 4G. THis is the most bizzare thing I have ever seen. I only get internet when I am on a phone call

This is supposed to be the opposite behavior. I've called Metro and they couldn't help me. I suspect this might be some weird Google Security issue. I can't seem to find anyone with the same issue I am having. I have tried all sorts of settings and now just reset my phone to factory again and I am getting the same issue

If you have access to another Metro pcs/Tmobile that has good data connectivity pull the sim (provided it fits) and test it on your S8. If you still have the same issues then you can effectively rule out a defective sim as the culprit.

Went to a Metro Store to swap out sims. Same issue

maybe try another reset, or go to sammobile and reflash the current firmware

When you performed the factory reset and logged back into your account, did you agree to restoring your apps and settings? You may have inadvertently restored the setting that's causing the problems.
