How to transfer your number from iD Mobile to Three Mobile?

1) Check you’re eligible to switch from iD Mobile

If you’re out of contract with iD Mobile, you’re free to switch network whenever you like and it won’t cost you anything.

In the event that you’re not sure of your contract status, customer support a call on 7777 from your iD Mobile phone. Or you can ring 0333 003 7777 from a landline or any other mobile phone (charges may vary).

Opening hours are 8am-8pm every day of the week.

Don’t want to speak to anyone? You can also find out your contract end date by logging into to your iD Mobile account. Or you can open up the iD Mobile app on your phone and find it there.

And if you’re interested in switching but want a bit more information first, text INFO to 85075.

2) Contact iD Mobile to cancel and get your PAC Code

Next up, you need to get in touch with iD Mobile. To do this, just text PAC to 65075 to get your PAC code. It’s this short, alphanumeric code that will enable you to transfer your existing phone number to the network you want to join. You don't even need to make a phone call.

If you'd prefer to speak to somebody, just ring iD Mobile on one of the numbers in step 1 and tell them you want to leave. While you’re on the phone to them, you also need to ask for your PAC Code.

It’s a legal requirement that networks provide you with a PAC Code within two hours of your request.

The important thing to note, though, is that your PAC Code will expire if it’s not used within 30 days.

If, for whatever reason, you don’t get around to using it in that timeframe you’ll need to contact iD Mobile again to ask for a new one.

3) Find and buy a new phone or SIM deal from Three

Out of contract and ready to switch? Good news. Your next task is to sign up for a new phone contract or SIM only deal from Three. Once you’ve passed Three’s credit checks, you’ll receive your phone in the post.

4) Contact Three to give them your PAC code

We’re almost there now. Next you’ll just to ring Three to give them your PAC. You can reach their customer support team on 0333 338 1001 from a landline (standard network rates apply).

5) Insert your new Three SIM card

If you got a new phone as part of your contract, take the pin-key included in the box and unlock the handset's SIM tray. Then insert your Three SIM card.

If you went for a SIM-only deal instead, you can just put the Three SIM in your existing phone.

While the number transfer is taking place, you’ll be given a temporary phone number that you can use and on which people can contact you.

6) Wait for your number to be transferred

The transfer should be complete the next working day. However, this can vary from network to network and sometimes depends on whether the day after you make your call is a working day or a weekend.
