Can't make cellular calls from iPhone 8 to iPhone XR
Hi,
So my brother blocked me for a period of time. I went into his phone and unblocked me, but I still can’t call him. He isn’t on do not disturb or anything. When I call him, it doesn’t even ring! It goes straight to voicemail. He has an iPhone XR with iOS 18.2 and I have an iPhone 8 with iOS 16.7.10. I can iMessage and FaceTime, but not cellular call. I can cellular call my mum with a android.
Thanks, all help is appreciated!
