Problems activating your SIM


More info

If your activation request has failed then there may be browser issues. Many activation problems are caused by storing build up, so it's worth clearing your browser history, restarting the browser and trying the activation process again. If this fails, try it in a completely different browser or PC.


Activation code problems


Lost activation code?


If you've lost the 6 character activation code (located on the credit card sized plastic and sticker which came with your SIM card) you can enter the 19 character code located on the SIM card.


Leave the last digit off the long SIM number.

So if you SIM number is 8935311100012345678 leave the 8 out and enter 893531110001234567.




"Sorry, that isn't a valid activation code”


If you get this message even after double checking the code you've entered is right then it's best to contact the care crew here - make sure to include the subject "activation code problem" in your message as well as the SIM serial number (the long number on your SIM card).



I didn’t receive my actication email. What do I do?


Oops we’ll sort that out for you.

You can re-request the activation email and we'll get it sent asap. You'll just need to enter your email address.
