Swapping your SIM card
If you get a new SIM card, you might want to swap your existing number onto it. We call this SIM swap.
Do you need to change your SIM if you’ve upgraded to a new phone with us?
Check your current SIM is the right size for your new phone. Unless you’ve just upgraded to 5G, if you’ve got a new SIM that’s the same size as your current SIM card, you don’t need to SIM swap. Just take the new SIM out of your phone and put your current one in. Throw the new one away and then just start to use your new phone as normal.
If your new phone takes a different sized SIM, you’ll need to keep the new SIM in it while you do your SIM swap. From your current SIM card simply text SWAP to 23424 and follow the instructions. This will swap your current mobile number onto your new SIM.
You may need to SIM swap if you’ve changed your phone or SIM card
Maybe you got a new phone from a family member or you’ve bought another phone from somewhere else?
If your new phone needs a different sized SIM card from your current one, or if you’ve just upgraded to a 5G phone, please contact us to get a new SIM card. When you get the new SIM, you’ll need to do a SIM swap: from your current SIM card simply text SWAP to 23424 and follow the instructions. This will swap your current mobile number onto your new SIM.
You’ll need a new SIM if your old SIM was lost or damaged and you don’t have your old SIM card
Once you’ve got your new phone or SIM, please follow the instructions on how to do a SIM swap. If you requested a replacement SIM from us over the phone because yours was lost or damaged, we’ll text you on your new SIM telling you how to transfer your number to your new SIM. Please make sure you reply with the 13 or 19 digit serial number on the back of your new SIM.
How to change your SIM (SIM swap)
- Save your contacts to your phone and back up anything you want to keep (photos, videos etc)
- Text SWAP to 23424 from your original SIM card and follow the instructions that we text back
- You may have a temporary loss of service during the next few hours as the new SIM activates
- Your number will be on your new SIM within 24 hours
If you’re on pay as you go, any credit or bundles will be transferred onto your new SIM.
