Phone showing wrong number on texts

[#1]

Hi, I have imported my old O2 contract number on to giffgaff. It's gone through ok but when I text people it comes through with the original giffgaff number on their phone. Any ideas?
I know the port went through ok as I do receive calls and texts off people who only know the number I ported in!!!!!
Help gratefully received

Go to Settings
Go to Messages
Switch iMessage off
Switch iPhone off
Connect to iTunes via USB (iPhone will switch back on)
Allow iTunes to check for updates (may not find any)
Sync iPhone with iTunes
Switch iMessage back on and allow to fully initialise
Once it's done, restart your phone


You can check that your phone has your right number in Settings > Phone > My Number. Just type in your new number if it's not already shown.



Hope this helps.

Is it an iPhone? Go to settings, phone, and look at the number. What shows? If it's the giffgaff one, change it to yours. Then, restart iMessage.

Hi Rob,

This is a common problem with iPhones after a number has been transferred

Try this procedure to correct the problem

1. Settings >> FaceTime > FaceTime > OFF
2. Settings > Messages > iMessage > OFF
3. Settings > Messages > iMessage > ON

Your phone should now check and set up your transferred number so verify this has happened here

Settings > Messages > Receive At > Phone
Settings > Phone > My Number

4. Settings > Facetime > Facetime > ON

Lastly, reboot the phone and also re sync it  to iTunes

In theory, your texts should now show the correct number

If your using a iphone switch off imessage and facetime then back on

I wish to god apple would fix this
