Hey! I suffered with no mobile data, or being able to make or receive calls or texts for about 2 weeks on my iPhone 11 Pro (since 14.5 beta). I couldn't even get One-Time pins for banking. I tried rebooting countless times - nothing. I had some limited success getting mobile data working by turning 4G off but calls still didnt work and the reception bars appeared greyed out when they were shown at all. Today I removed the beta profile, restarted the device and then re-added the profile and rebooted again. Not sure if it was just a fluke but now my iPhone 11 Pro is working as it should on 4G. I never had any VPNs installed either. I just wanted to post here in the hopes that it might help one person fix their issue too.
