"My phone has been switching in and out of SOS mode for the last three weeks. Airplane mode on and off has cleared but now I am unable to get out of it and I can’t remove my SIM card: shut off and on, then on and off airplane mode is no longer clearing SOS mode."

Getting Out of SOS Mode:
SOS means that you do not have Cellular service at this very moment, but you do have the option to make emergency calls. So, contact you Carrier to get your services back up and running.
