My data isn't working

If you've just activated your SIM and you've got a signal, you might need to check a couple of things to get your data working.

  1. Check that you have Data Roaming & Mobile Data turned on in your Settings.
  2. Make sure that you have changed your APN settings to match the following:
    Name: 3
    APN: three.co.uk
    User name: [leave this field blank]
    Password: [leave this field blank]
    MMSC: http://mms.um.three.co.uk:10021/mmsc
    MMS proxy: mms.three.co.uk
    MMS port: 8799
    APN type: internet + mms
  3. Restart your phone

My device says "No Service"

If you've inserted the SIM into your phone and you didn't get a 'Welcome' text message or it says 'No Service', you will have to manually select a network through your settings.


Settings > Mobile > Network Selection > Disable Automatic > Wait for networks to pop up and select one


Settings > Connections > Mobile Networks > Network Operators > Search networks manually > Wait for networks to pop up and select one

If it doesn't connect, you might need to click on one a couple of times and then restart your phone.

Note: May differ depending on your device - If these instructions don't match, explore your settings until your find Network Selection or Network Operators

Which one do I choose?

Try any of them, and if it doesn't work, try another one!

It's still not working...

Try the SIM in another phone if you can, and see if it'll activate.
