Lost network Connectivity s21 Ultra

[jimmyrinse]

Had the phone since release day with no issues until today, not sure if its anything to do with the update that was released today or not.

Started throwing up a roaming error even though i'm at home which went on and off a few times, now I have zero connectivity from my sim it just shows like a no entry sign where my signal strength should be.

I've tried restarting the phone, resetting network settings, tried sim in another phone, put 2 sims into the s21 but both show no signal, manually set up apn settings with no change.

Hi try resetting your network settings, that should fix the issue.

[jimmyrinse]

Already done that with no change

Take out your sim first then reset the network settings then put it back in turn the phone off then back on & see if that way works.

Hi

if you tried your sim in another device to no avail you may need a SIM swap. Best to contact your network provider to arrange for you. Good luck

have you tried clearing phone cache just sounds like the old and new update are conflicting with etc other.

SIM works fine in another device, also tried sim from a working phone on a different network - offers me choice of network so i choose vodafone then immediately goes to no network. Doesnt appear to be trying
