I've had the phone for quite a long time now, but I'm slowly becoming more and more dissatisfied. At least once a day, the reception is suddenly gone. Then the only thing that helps is deactivating the sim card and activating it again. The sim card is a new one. Then I don't get any calls, messages or the like. The mobile phone is lying on the table, doesn't ring, and a few seconds later I get a message that the recipient has tried to call. A lot of people report this on the internet... Does anyone have any help?

Answer

I know this problem too. I went to Digitec and several times to the Swisscom shop. It is mentioned on the internet that the OnePlus 8 has problems with VoLTE and VoWifi. I tried it with a new sim card, but that didn't help either. The only thing that helped was deactivating 4G, i.e. setting the sim card to 2G/3G. With this setting, the mobile phone has been working without any problems ever since. I don't know how it is with other providers (I have Swisscom). Digitec or OnePlus should do something about this with Swisscom.
