Can’t accept or call on FaceTime
Hi I don’t have a phone number. I use iPhone 7 my software is up to date but I can’t accept or make calls via FaceTime video or audio. I use my gmail.com as my Apple ID but every time I try to call someone it says FaceTime failed for them and when someone calls me and I press answer it says FaceTime failed. So basically every time me or anyone I call press the green button it automatically says FaceTime failed. I also tried to toggle the off switch in setting of FaceTime and then reset the phone but nothing changed I also tried to update my iPhone but still I can’t make or accept FaceTime video or audio calls. Anyway you can help?
iPhone 7, iOS 14
