How do I find out which app is charging my carrier for an iMessage
A message keeps coming up on my iPhone "Your carrier may charge for an iMessage". I removed all the possible apps such as Facebook, Messenger, Instagram, but I still get the message every day. I tried choosing Cancel, which seems to prevent a message charge on my phone, but would like to use all my favourite apps without getting charges. Apple have provided no traceability, as the carrier can only say that they are being charged by Apple. Any hints? Thanks so much 🙂
iPhone 4S, iOS 9.3.5
