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

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

Step 1: Get a PAC Code from Vodafone

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

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

1. Online: You can get a PAC Code from Vodafone by logging in to the My Vodafone website. Once you've logged in, go to Account settings > Mobile switching.
2. By Text Message: You can get a Vodafone PAC Code sent to you via SMS text message. Text PAC to 65075 to receive a PAC Code from Vodafone.
3. By Phone: You can get a PAC Code by calling Vodafone. To do this, call them on 191 using your Vodafone handset. Alternatively, dial 03333 040 191 from any other phone. You'll need to call during Vodafone's opening hours (Monday-Friday 8am-9pm, Saturday 8am-9pm, Sunday 8am-9pm).

Here are some key things to know:

• A PAC Code is 9 digits long and follows the format ABC 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 Vodafone: it'll be closed automatically when your phone number is transferred to O2.

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

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

Step 2: Order your new phone or SIM card from O2's website

You should now order your new phone or SIM card using the O2 website. Please select the type of tariff you're intending to move to:

• Pay Monthly
• SIM Only
• iPhone
• Samsung Galaxy
• Pay As You Go
• Free SIM

If you're looking for a SIM card from O2, the following deals from £8/month are currently most popular:

Network	Data	Monthly Cost (will rise each April by RPI inflation plus 3.9%)
Unlimited mins Unlimited texts	40GB data	£8.00 per month 12 month contract	See deal
Unlimited mins Unlimited texts	60GB data	£9.99 per month 12 month contract	See deal
Unlimited mins Unlimited texts	Unlimited data	£20.00 per month 24 month contract	See deal

For a full list of available tariffs and the latest O2 deals, please refer to this page on O2's website.

Alternatively, if you're getting your O2 plan from a reseller, tap on their logo for more information:

O2 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 O2.

Step 3: Give the PAC Code to O2

Once your new phone or SIM card arrives from O2, 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 O2 and provide them with your PAC Code from Vodafone.

Your PAC Code should be entered on O2's online form. You can also provide your PAC Code to O2 over the phone:

If you're joining O2 Pay Monthly, you can submit your PAC Code by calling 202 on your O2 handset. Alternatively, call 0344 8090202 from any other phone.

Alternatively, if you're joining O2 Pay As You Go, submit your PAC Code by calling 4445 (0344 8090222 if you're calling from another network).

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

Remember:

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

Step 4: Phone Number Transferred (Next Working Day)

Once you've provided a PAC code to O2, your phone number transfer will normally be scheduled for the next working day (Monday to Friday only, excluding English bank holidays).

On the day of the transfer, you'll momentarily lose coverage on both mobile networks. When this happens, restart your handset on O2. You should find that the O2 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 O2, your account on Vodafone will automatically be closed. You'll receive a final bill from Vodafone for any outstanding charges.
