Harry_96 , via OnePlus 6 , Aug 1, 2020 : I recently changed my sim to vodafone and now I can't make any calls and send or receive sms. Nor do I receive calls. I tried several other vodafone sim and still doesn't work. Other networks seem to work just fine. What could be the problem? Is there a solution to this other than porting to another sim?

Harry_96 , via OnePlus 6 , Aug 1, 2020 : It's not about the sim. I tried the sim on other devices and works fine.
drl431 , Aug 1, 2020 : Is this sim new? If you do a Vodafone search, seems most issues are with VoLTE and VoWiFi: https://forums.oneplus.com/search/499439612/?q=vodafone&o=date&c[title_only]=1
