Problems updating iphone 5 to ios 7

We suggest trying a process of elimination to see if i Message works with just your mobile number or just an email address.Also check there is a tick beside your phone number in the Start New Conversations From section if you're using an i Phone.

As an alternative to Apple's page, you could try Down Detector, which provides a graph detailing outage reports from the past 24 hours, and even an outage map to see whether you're in an affected area.

That last tip will only work with an i Phone, though.

i Message - accessed via the Messages app in i OS or mac OS - enables users to send messages to other people using i Phones, i Pads and Macs for free.

i Messages are indicated by a blue bubble, while normal text messages (which you might have to pay to send depending on the terms of your phone contract) are green.
