Activation code problems. 


Where's my activation code

Your SIM activation code is located on the credit card sized plastic packaging that you would of removed your SIM from. It's typically 6 characters long and it's be right under your PIN & PUK code. 


I lost my activation code? 

If you've lost your 6 character activation code then you can enter the long number thats on the back of your SIM. You'll just need to add these 5 digits first 89353. So, if your SIM number is 1110001234567 then add 89353 meaning you'll enter 893531110001234567. 

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

If you get this message even after double
/triple checking you've entered the right code then it's best to contact the Care Crew here - make sure to include in the subject "activation code problem" as well as your 19-digit SIM number (the long number on your SIM).
