SIM card re-activation

Erik — Tue, 04 Jan 2022 21:09:43 GMT

I changed SIM card during my trip to overseas and switched back to my original phobic mobile SIM card yesterday. However, I cannot use Internet. What do I need to do to make it work again?

my situation is:

—i use iPhone 6S

—my IOS is the latest, and I tried restarting the phone but didn’t work

—celler data is on and I can make phone calls

—i received an error message says “cannot activate celler service” when I updated my IOS

Great work, @specialK! Honestly I'd never given that KB article much attention before but it's quite helpful indeed. Glad you were able to point @Erik in the right direction. 🙂
