Transfer A Phone Number From O2 to iD Mobile: Step-By-Step Instructions

Switching from O2 to iD Mobile? It's a straightforward process to keep your existing phone number.

Step 1: Get a PAC Code from O2

If you’d like to move your phone number from O2 to iD Mobile, the first step is getting your Porting Authorisation Code (or PAC Code) from O2.

There are three ways to get a PAC Code from O2:

1. Online: You can get a PAC Code from O2 by logging in to the My O2 website. Once you've logged in, go to My details > Thinking of switching from O2?.
2. By Text Message: You can get an O2 PAC Code sent to you via SMS text message. Text PAC to 65075 to receive a PAC Code from O2.
3. By Phone: You can get a PAC Code by calling O2. To do this, call them on:
   • For O2 Pay Monthly, dial 202 (or 0344 8090202 from any other phone)
   • For O2 Pay As You Go, dial 4445 (or 0344 8090222 from any other phone)
   You'll need to call during O2's opening hours (Monday-Friday 8am-9pm, Saturday 8am-8pm, Sunday 8am-6pm).

Here are some key things to know:

• The PAC Code from O2 should consist of six numbers with TEL at the start (e.g. TEL 123 456).
• Your PAC Code is valid for 30 days. If you don't use it during this time, the PAC Code will expire and you'll need to request a new one.
• You shouldn't close your account at O2: it'll be closed automatically when your phone number is transferred to iD Mobile.

Still in contract with O2? If so, you may need to pay an early exit fee on your bill from O2. To find out how much this would be, text INFO to 85075.

Don’t want to keep your O2 phone number? You can switch to iD Mobile without taking your phone number with you. If you'd like to do this, get a STAC Code from O2 instead.

Step 2: Order your new phone or SIM card from iD Mobile's website

You should now order your new phone or SIM card using the iD Mobile website. Please select the type of tariff you're intending to move to:

iD Mobile will assign you with a temporary phone number during the transition process. This will allow you to test out the service before you finally transfer your phone number to iD Mobile.

Step 3: Give the PAC Code to iD Mobile

Once your new phone or SIM card arrives from iD Mobile, switch it on and make sure everything's working properly. If, for whatever reason, you need to return or change the handset or SIM card, it's best to do this before transferring your phone number.

Once you're happy to continue with the phone number transfer, contact iD Mobile and provide them with your PAC Code from O2.

Your PAC Code should be entered on iD Mobile's online form. Alternatively, you can give the PAC Code to iD Mobile by calling 7777 on your iD Mobile handset. You can also call 0333 003 7777 from any other phone.

If you have a STAC Code from O2 rather than a PAC Code, this can be provided to iD Mobile in the exact same way.

Remember:

• You must provide the PAC Code to iD Mobile within 30 days of it being issued by O2. If the PAC Code has already expired, you'll need to return to step 1 and request a new PAC Code from O2.
• O2 Pay As You Go customers: Try to use up your remaining credit as it can't be transferred to iD Mobile.

Step 4: Phone Number Transferred (Next Working Day)

As long as you've submitted your PAC Code to iD Mobile before 6pm, your phone number transfer will normally be scheduled for the next working day (Monday to Friday only, excluding English bank holidays). After 6pm, you'll need to wait one extra working day for your number to be transferred.

On the day of the transfer, you'll momentarily lose coverage on both mobile networks. When this happens, restart your handset on iD Mobile. You should find that the iD Mobile phone or SIM card will now associated with your original phone number.

• If you see an error message (e.g. "SIM card registration failed"), this means it's time to restart your phone.
• Once the phone number has been transferred to iD Mobile, your account on O2 will automatically be closed. You'll receive a final bill from O2 for any outstanding charges.
