How to perform a Manual Roam

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

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

Generic method

  • 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.

Method for iPhones

  • 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).

Method for Android

  • Go to Settings and then Wireless networks.
  • Go to Mobile networks and then Network operators.
  • Search for networks.
  • Select a network other then O2-UK.
  • Wait until it fails to connect.
