My zenfone 8 (model# ZS590KS) (2.5 years old) lost its wireless connectivity, but I was still able to get texts & emails via wifi but no phone calls. I switched the sim card to slot 2 & that resolved the issue somewhat. Now when I travel out of town the same thing happens but then it works when I return home. My spouse has the exact same phone and has no issues out of town (in the same place where I was). I have replaced the sim card, that did not fix the issue. Additionally, when I power down the phone & power it back up when out of town, my phone will connect to the wireless for about 5 minutes then drop the wireless again. I was told by an AT&T sales person that this might be a sim card reader issue & probably better to replace the phone than spend the money to repair it. Suggestions? Thanks.
