Problem with my apple ID for Facetime and Imessage
Hi,
I'm new to the Iphone. I recently just bought an iPhone 5S. It works fine, except for the imessage and Facetime. My apple ID does not seem to work on these two softwares because it keeps saying 'error occured during activation'. However, when i put my apple ID into my friend's iphone 4S (iOS 7), i can use my apple ID for imessage and Facetimen perfectly. It's been going on for almost a month.Is there something wrong with my apple ID or my phone? My phone is fully updated, iOS 8.3. Does it have to do with the wifi connection i'm using as well?
Please help. Thanks
