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

Step 1: Get a PAC Code from EE

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

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

  1. Online: You can get a PAC Code from EE by logging in to the My EE website. Once you've logged in, go to Menu > Account settings > Leave EE.
  2. By Text Message: You can get an EE PAC Code sent to you via SMS text message. Text PAC to 65075 to receive a PAC Code from EE.
  3. By Phone: You can get a PAC Code by calling EE. To do this, call them on 150 using your EE handset. Alternatively, dial 07953 966 250 from any other phone. You'll need to call during EE's opening hours (Monday-Friday 8am-8pm, Saturday 8am-6pm, Sunday 8am-6pm).

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 EE: it'll be closed automatically when your phone number is transferred to O2.

Still in contract with EE? If so, you may need to pay an early exit fee on your bill from EE. To find out how much this would be, text INFO to 87075.

Don’t want to keep your EE 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 EE instead.

EE STAC Code (Leave EE Without Keeping Your Number)

If you’d like to leave EE without keeping your phone number, you’ll need to request a STAC Code rather than a PAC Code. There are three ways to get a STAC Code from EE:

  1. Online: You can get a STAC Code from EE by logging in to the My EE website. After logging in, go to Menu > Account settings > Leave EE.
  2. By Text Message: You can get an EE STAC Code sent to you via SMS text message. Text STAC to 75075 to receive a STAC Code from EE.
  3. By Phone: You can get a STAC Code by calling EE. Call them on 150 using your EE handset. Alternatively, dial 07953 966 250 from any other phone. You'll need to call during EE's opening hours (Monday-Friday 8am-8pm, Saturday 8am-6pm, Sunday 8am-6pm).

Once you’ve gotten your STAC Code from EE, the rest of the process for joining O2 remains the same.

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:

If you're looking for a SIM card from O2, the following deals from £10/month are currently most popular:

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 EE.

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 EE rather than a PAC Code, this can be provided to O2 in the exact same way.

Providing your PAC Code to O2
The PAC Code should be submitted through a form on O2's website.

Remember:

  • You must provide the PAC Code to O2 within 30 days of it being issued by EE. If the PAC Code has already expired, you'll need to return to step 1 and request a new PAC Code from EE.
  • EE 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 EE will automatically be closed. You'll receive a final bill from EE for any outstanding charges.

  • Hello – I started on Orange pay as you go back in 2001 with an old nokia 3310 – that phone became a nokia 1800 still on orange pay as you go and has now ended up on EE – same number all that time and a replacement SIM when the old one stopped working… always ‘pay as you go’. It’s an expensive year if it needs a top-up of £30!
    The phone is used very infrequently and today I received a message from EE/BT amounting to ‘use it or lose it’. Fair enough.

    That did prompt me to look at what EE charge and at 35p per min and 15p text, even though very low usage, your comparison chart on:
    https://kenstechtips.com/index.php/compare-pay-as-you-go-networks
    is making a switch to O2 look like better value.

    I want to continue with the old phone as is but just change provider from EE to O2, but on your article about using PAC codes it says:
    “After getting a PAC Code from your old network, the next step is ordering your new phone or SIM card from your new mobile network.”
    Am I going to need a new SIM from O2 (is that even possible for such an old style phone!?) or should it be possible just to switch networks with existing phone and SIM?

    Thank you.

    • Hi Graham,
      Thanks for your comment. Yes, you’ll need to order a new SIM card from O2, which can slot inside your existing Nokia 1800 providing it isn’t locked to Orange/EE. You’ll be glad to know that it’s still possible to use standard-sized SIM cards (also known as Mini-SIM/2FF) – just make sure you pop it out at the outermost groove when your O2 SIM card arrives in the post. Once you’ve activated your O2 SIM card, you can use the PAC Code to move your phone number from EE to O2.
      One thing that’s worth noting is you won’t be able to move your credit from EE to O2. For this reason, it might be worth waiting if you have a large balance on your EE SIM card – it’s best to try and use this up before moving to O2.
      Hope this helps,
      Ken

  • Hi Ken,
    My phone contract with EE has ended and I have got a PAC code as I would like to take out a contract with O2 and keep my old number. I have found a very good deal on mobiles.co.uk for a pay monthly contract with O2 however I am unsure how I can use my PAC code and keep my number if I am not buying from O2 directly?
    Thanks for your help 🙂
