I have had a Galaxy J7 Refine roughly a year now. Just yesterday my phone stopped recognizing my sim card. Now I can no longer use mobile networks.
I've run through the basics:
Shut down, remove and reseat sim card.
Complete factory reset. Which has now made my life much harder. (I use my phone for work extensively)
My phone has shown no signs of overheating.
Sim card looks normal (Undamaged)
Need help. My job requires me to be on-call basically 24/7.
As far as I can tell posting here is the only way to get to any sort of chat support. Any help would be appreciated.
Hi there! Definitely wanna look into that for you. Have you made any changes to the software of the device (root, flash, unlock, etc..)?
The only changes I have made recently were to install standard updates, however I installed updates after I started having the sim card error.
