Hi just update my phone and 4g 5g not working anymore.... is anybody else having issues since the recent up date ?? Iv got it working on 3g 2g and not impressed. Also just realised iv been reading and it's saying all samsumg s20 come with dual sim card tray mine has 1 sim card tray is this correct??
if you put sim into sim 2 which is the sd card slot but turn the sim to fit it also in sim 1 slowly go up from 2g 3g to 4g one at a time in settings works until you reboot ya phone but moving to sim 2 is best until samsung fix problem
sorted it thanks not moved sim went back in to settings turned mobile data off and set it to 3g 2g and turned it on came on. left it on this for at least half hour then went back in to mobile settings and switched it to 4g 3g with out disabling mobile net work and it switched to 4g 3g and still working know 🙃
