Hi, a couple of days ago my Samsung s21fe started to have issues with connecting to mobile network service on both of my sim cards. I cannot connect to any network, it says "service unavailable", or "emergency calls only". Calling doesnt work, mobile data doesnt work, sms does not work on either sim card. I have tried this:
1. Put the sim cards into a different phone. They worked, so the problem is on my phone.
2. Restarted my phone multiple times.
3. Turned airplane mode on and off.
4. Reset network settings on both of my sim cards.
5. Manually chosen mobile network provider, reset APN settings. Then also reset to automatically choosing network provider. Neither fixed the issue.
None of these methods worked. The icons on top (for both simcards) still either look like this 🚫, or show very weak signal, but even then I cannot call because it says "emergency calls only". Mobile data does not work on either simcard, roaming or not roaming. All of these worked when i placed the simcards into a different phone. My s21fe phone did not fall, was not damaged in any way. I have never had this issue in the past. It randomly appeared one day. Will a factory reset help? Is it a hardware problem? Please advise.
