I recently got the ATT branded unlocked Lumia 640 and am using a sim card from Lycamobile (MVNO using TMobile towers)
I compared it to a TMobile branded Lumia 521 switching the same sim card between phones and have noticed that there is only ONE reception bar on the ATT L640 phone and TWO bars on the TMo L521.
This is inside my home where reception is iffy to begin with.
Any suggestions as to what the issue may be?
