For Android devices in general:
- Launch the SMS application on your phone
- Tap on Menu and go to Settings
- Scroll down and select 'Message Centre' (If you cannot find Message centre in this list then look for and tap Text message and it should hopefully be in this list)
- As soon as you open that you'll be able to see and edit the message centre number
- If needed, enter in the correct number +447802002606
- Restart your phone and send test text to check its working
If your Android phone doesn't have the
'Message Centre' option available then you can find out what it is by:
- Typing ##4636## into your phone on the dial screen
- Select Phone information
- Scrolldown and select the SMSC setting
- Press Refresh to see the current setting (which should hopefully be the one you're looking for)
- If this number is wrong then type in the correct one and press Update
- If you get a notification saying update error then it's probably because you have Android 2.3 or higher and so will have to enter the UDP number which is: 0791448720006260
- Restart your phone and send test text to make sure its working
