This may be a problem with your SIM Provider and as a result, you may need to change your network. Have you tried inserting different SIMs, to see if the issue still persists? 🤔

I've to Sims in my phone from different providers and I've the same problem on both.

It's getting frustrating tbh

I have the exact same issue, I have two sims from two different countries and both have the same issue. I tried switching them around in the sim slots but the same issue happens on both slots for both sims.

 

This is a real deal breaker issue, and the weird part that the phone was fine until around june.

Im facing the same problem in my s21. My mobile data drops every 5mins or so. I have done all the diagnostics listed above. My wife's S7 does not drop internet though both our sim card are from the same network, Three UK. How can we escalate this for them to release a fix patch. I noticed this started around august to september

When did this start happening for you? For me it was between September and October.
