My mobile phone disconnects the internet when both sim card slots are in LTE mode I see the normal 4G signal in this mode, but I don't have internet. But when I put one of the SIM card slots in 3g mode, the other SIM card works properly. And the 4g+ sign will appear. I have had this problem for several months. The problem is not from a weak antenna because I tested in different places. I reset the device settings and even did a factory reset. But I still have a problem.
I am using the latest version of Android 13 and the new Samsung update ONEUI 5.0 Please guide me if this is a hardware or software problem?
Hello, majidpt, and welcome to the Community. I am sorry to hear you are experiencing internet connectivity issues in LTE mode. Since you already reset device settings and performed a factory reset, the only further recommended step is to contact your carrier for further assistance, since they manage your network and data services. I apologize for the inconvenience.
