You will need to activate your 48 SIM to receive your free 1GB and begin using 48 Mobile.  

Once your SIM is active, move your existing number or receive a new one from us. If you are not ready to move your number immediately, then opt to take a temporary number and you can move your existing number later.  

Activating and moving your number is swift and to the point, and you can find a separate detailed guide here.

How do I move my number?

We've put together a step-by-step guide, so there's no surprises and you know exactly what you need to do to move your number. Read the full steps and more useful information, here.  

Activation code problems

I lost my activation code? 

If you have lost your 6 character activation code, you can activate your SIM by entering the long number on the back of your SIM Card, it will look something like this: 1122333445556BB

Enter 893531 and include the first 12 digits of your SIM number (exclude the last digit & both alphabetical letters), now select "activate", and you're in action! Example: 893531112233344555                                                                                                                                                 

Problems with activating a SIM

If your activation request has failed, it's worth clearing your browser history, restarting your browser, and then trying the activation process again. Alternatively, try a completely different browser or device.  

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

If you have received an error message and have double/triple checked that you're entering the right code/SIM number, you can get in touch with 48 Customer Care, here. Have your SIM number available to share when you contact us so that we can get you back in action fast.
