Hi having several problems since using Virgin sim. Incorrect telephone number showing on "my number" Can't use Safari using mobile data but other apps work ok even when there's a strong signal. Wi-Fi calling when I'm at home won't work phone will only use weak mobile signal so telephone calls are really poor. All used to work perfectly before changing over to Virgin sim. Tried removing and reinserting sim several times, turning phone off and on etc. no change. All settings seem correct on my iPhone
