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

Step 1: Get a PAC Code from Three

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

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

  1. Online: You can get a PAC Code from Three by logging in to the My3 Account website.
  2. By Text Message: You can get a Three PAC Code sent to you via SMS text message. Text PAC followed by your date of birth in DDMMYY format to 65075 to receive a PAC Code from Three.
  3. By Phone: You can get a PAC Code by calling Three. To do this, call them on 333 using your Three handset. Alternatively, dial 0333 338 1001 from any other phone. You'll need to call during Three's opening hours (Monday-Friday 8am-8pm, Saturday 9am-6pm, Sunday 9am-6pm).

Here are some key things to know:

  • The PAC Code from Three should consist of six numbers with HTG at the start (e.g. HTG 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 Three: it'll be closed automatically when your phone number is transferred to Vodafone.

Still in contract with Three? If so, you may need to pay an early exit fee on your bill from Three. To find out how much this would be, text INFO followed by your date of birth in DDMMYY format to 87075.

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

Three STAC Code (Leave Three Without Keeping Your Number)

If you’d like to leave Three 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 Three:

  1. Online: You can get a STAC Code from Three by logging in to the My3 Account website.
  2. By Text Message: You can get a Three STAC Code sent to you via SMS text message. Text STAC followed by your date of birth in DDMMYY format to 75075 to receive a STAC Code from Three.
  3. By Phone: You can get a STAC Code by calling Three. Call them on 333 using your Three handset. Alternatively, dial 0333 338 1001 from any other phone. You'll need to call during Three's opening hours (Monday-Friday 8am-8pm, Saturday 9am-6pm, Sunday 9am-6pm).

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

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

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

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

Vodafone 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 Vodafone.

Step 3: Give the PAC Code to Vodafone

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

Your PAC Code should be entered on Vodafone's online form. Alternatively, you can give the PAC Code to Vodafone by calling 191 on your Vodafone handset. You can also call 03333 040 191 from any other phone.

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

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

Remember:

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

Step 4: Phone Number Transferred (Next Working Day)

As long as you've submitted your PAC Code to Vodafone before 5pm, your phone number transfer will normally be scheduled for the next working day (Monday to Friday only, excluding English bank holidays). After 5pm, 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 Vodafone. You should find that the Vodafone 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 Vodafone, your account on Three will automatically be closed. You'll receive a final bill from Three for any outstanding charges.

    • Hi Micha,
      Thanks for your comment. Yes, it should be possible to cancel your contract as a 14-day cancellation. You’ll need to give Three’s customer services team a call on 333 to process this cancellation.
      Hope this helps,

    Hi, I am Eiralyn. I didn’t know that I my contract renewed because they (three network) didn’t give me any notice that it was nearly ending my contract so it was automatically renewed. Since that happened, I just continued using my phone and date without any knowing that new contract has started. No, I wanted to move to Vodafone but I think I have bill to pay for Three since my contract automatically renewed. What should I do?

    • Hi Eiralyn,
      Thanks for your comment. At the end of your 24-month contract, your existing price plan will normally continue but on a one-month rolling basis (i.e. it doesn’t automatically renew for a further 24 months). Therefore, you can just follow the normal process for moving from Three to Vodafone without any issues or early termination charges.
      Hope this helps,
      Ken

    Hi
    Mi name is Gabriel and I’m an three network client. I want to switch to Vodafone network but I’m still on contract till 2 September 2020. I don’t know if is possible to switch or I have to wait until my contract expires.

    • Hi Gabriel,
      Thanks for your comment. You can move to Vodafone whenever you like, but it’s likely you’ll incur an early termination fee as there are still 11 months remaining on your contract. There’s more information here on what this charge is likely to come to (text INFO followed by your date of birth in DDMMYY format to 85075 to find out the exact amount you’d be charged).
      Hope this helps,
      Ken
