I will be travelling overseas without mobile data. International SMS will be set up, but I have iMessage linked to this mobile number. I have other iPhones, iPads and Macs which also receive iMessages on this account.

Do I have to disable iMessage on all my devices before I travel to ensure when people send a message to my mobile number, I will receive it as an International SMS?

Thanks in advance.

  • Only if you have a provider that gives you International access. So check with them. – Ruskes Nov 10 '14 at 3:00

Simple answer, yes.
If you want SMS to arrive at your phone there must be no other device left active that can possibly pick up the iMessage.

Otherwise Apple considers that if any device received the iMessage, it is considered delivered & will not try again as SMS.

  • This makes sense. I'm wondering if it would be possible to turn Airplane mode on the other devices as a possible quick and easy solution? – bassplayer7 Nov 11 '14 at 3:31
  • That will work too - but if you're away for more than a few days, leaving the other devices behind, might as well switch them off – Tetsujin Nov 11 '14 at 7:40

When there is not any internet connection SMS messages should be delivered to your phones, so you should not need to disable iMessage anywhere. However just to be on the safe side, I would recommend you to disable it. It would be a fail proof way to feel safe about SMS/iMessage mystery.

If you use only your phone number as your iMessage account you can just disable it in all your devices to be sure that you will get all SMS messages.

If you have any e-mail address associated with your iMessage account, you can just remove your phone number from iMessage accounts in your devices and keep your e-mails. That way you can still receive iMessage, whenever internet connection is available.
