It may be your carrier problem 🤷🏻♂️ or the area you live in right now may be causing this issue otherwise my mom is using the m30s and it's doing pretty well on the network side 😌
Network issues? When while in call or data. Yes issues are present with data but not calling. I have airtel connection which is good in my area in both data and calling. But I also face issues with speed. So I suggest you to check the same sim in different divice, note the stable bars you are getting, check speed using speed test, fast etc. If you have issue in that device too then go to carrier store or call CC explain your problem.
Please be assured and to resolve network issue please follow below given steps:-
1. Check network operators and select automatically (Settings> Connections> Mobile Network>Network operator> select automatically > Tap on OK > Registered on network).
2. Check device in safe mode: Press and hold the Power key, when Power off icon appears >Press and hold the power off icon. Exit safe mode: Hold the power button and select restart on the device.
3. Reset the device: settings >General Management > Tap on Reset. Note: Before reset make sure to have back up of the data via Smart Switch Mobile App (Install Smart Switch App > Open > Click on Memory Card Icon >Back Up option > Choose the data for Back up > Back Up).
If the issue still persist, kindly register your concern in Samsung Members app (Samsung Members app > Get help > Feedback > Error report/ask question). Note: Please send device log files within 15 minutes of issue occurrence along with the exact issue details.
