C510 will only MMS not SMS

Hi, all you need to do is contact your service provider and ask them for your correct message center number they will give you this for free over the phone but also ask them to send you the correct mms and internet settings to your phone they send you these via txt message and this will update your phone to the correct settings to ensure your being charged correctly as you can be over charged if your using cross network settings.

You may also be able to get the settings from your service providers website as orange are pretty good so you could always have a look their first but if not just ring orange from your phone and ask them to send you the correct settings they dont charge for this and it just updates your phone to the latest settings.

Let me know how you get on or if you need further assistance ok
