Hi
Today I went to turn my data on and it said insert sim card. My sim card hasn't changed and has always been in. I went into sim manager to turn it off and on again but it's not letting me. I press confirm to turn it off but it stays showing as on, even though it's not registering. I have restarted my phone multiple times but no help. I have also tried installing the software update but it keeps giving me unknown error. It's a samsing s22
