I have replaced the sim - turned off/on, airplane mode, been advised it might be 3G switch however a friend on ID still had service when they were in the same location as me. Was able to make/receive calls when first switched the sim. Took sim out and replaced back in - was able to make calls for a little while and now back to unable to make calls. I’m in DE4
