A manual roam basically means resetting your phones network connection so it can get a nice, shiney, new, fresh connection to giffgaff.  It can solve lots of problems such as:

  • Poor or no signal
  • Inablility to send or receive SMS messages (SMS service centre number)
  • Slow data speeds
  • Intermittent data
  • Inablility to connect to data while roaming

More Information

  • Go to Settings
  • Then go to Mobile networks and select a network other than O2-UK, giffgaff, Tesco Mobile or other O2 MVNOs. For example, try Vodafone, EE or 3
  • When you exit the menu the phone should lose the network.
  • Repeat the process and select O2-UK as your mobile network unless you're abroad in which case you should select "select automatically"

This procedure will also force the update of the message centre number. You can verify it in your message settings.

The SMS Service Centre number is +44 78020 02606 and can be checked by dialling *#5005*7672# from the device keypad.

  • Go to Settings and then Carrier (or Mobile Data -> Network Selection for newer versions of iPhone)
  • Toggle OFF the automatic mode and manually change the carrier to something other then O2-UK.
  • Leave the menu and wait until it fails to connect to another carrier.
  • Once it fails, repeat the process and this time choose O2-UK or toggle ON automatic (preferable).
