View originalDid you put your SIM card in it? Is your SIM inserted the correct way? Is your SIM activated?
We're you able to try syaoran's suggestions? We also have some additional steps to try here: Signal issues / no service troubleshooting | T-Mobile Support
This is also happening to me, and, I also randomly receive the "server unreachable" error. I have brought it back to TMobile several times and they have replaced the SIM card...STILL...nobody knows how to fix this. I had a ZTE that worked perfectly...this Samsung is a piece of garbage...
I had the exact issue, with the same phone. I now have a Samsung A20 too. TMo technician had me change the mobile network to work better with the tower in my area. The tower is LTE/3G and 4G. I needed to change my settings on phone to be LTE/3G. What I had previously was LTE/2G/3G. My tower is heavily trafficked and needed to be able to communicate better with my phone.
Again….change your mobile network on your settings to agree with your tower, most likely LTE/3G.
Call a Tmo tech - not a rep - but a technician if you need help doing this.
