We've put together a quick and easy to use switching guide. Our guides allow you to select the network you wish to switch to and from, and you will be given a step by step guide on how to keep your number and move to a new SIM Only Deal.

It is worth noting that if you wish to join EE and get a new number then you can use a STAC code in order to get a new number and will cancel your existing contract.

Joining EE and leaving Tesco Mobile

Joining EE and transferring your number from Tesco Mobile is a simple process and usually takes no longer than 1-2 working days.

The process which will go through in more detail below involves requesting a PAC code from Tesco Mobile and handing it to EE.

You can either hand the PAC code over to EE during the ordering process or after you have received your new SIM card or eSIM has been activated.

1. Request a PAC code from Tesco Mobile

Switching from Tesco Mobile is quick and easy. You even get to keep your current number! There is no need to memorise a brand new phone number or update all your contacts.

Here is how the switching process works:

• Text: From your Tesco Mobile number, text PAC to 65075 for free. This is a universal number created by Ofcom to make the switching process easier. You will receive a reply within 2 minutes containing your PAC code.
• Online: Contact Tesco Mobile via the online live chat service and request a PAC code.
• Phone: Call 4455 from your Tesco Mobile number or 0345 301 4455 from any other number.
• Store: Find your nearest Tesco Mobile store and inform the assistant that you want to leave.

Note: You can request a PAC code from Tesco Mobile before getting your new SIM card, as the code is valid for 30 days.

If you want a new number and do not wish to keep your current number, you will need to request an STAC code instead of a PAC code. Text "STAC" to 75075 to get your STAC code.

2. Order a SIM only deal from EE

If you already have your new SIM Card, feel free to skip to step 3 of this article

During the ordering process you may be given the opportunity to share your PAC code from Tesco Mobile to EE, if you choose this option then the number transfer process will start once your new sim card arrives and you activate it in by putting it in your phone and turning it on, this also means you can skip to step 4 of this article if you wish!

If you are not given the opportunity to hand over your PAC code when ordering then there's no need to panic. Once your new sim card from EE has arrived, just continue to step 3 of this article.

It is also worth calling out that it doesn't matter if you are able to hand over your PAC code from Tesco Mobile whilst buying your new sim from EE or not it's just slightly more convenient but the outcome is the same!

3. Give the PAC code to EE

Once you have your PAC code, follow these steps to give it to EE:

• Online: Give your PAC code to EE via their online transfer form.
• Phone: Call EE on 150 from your EE phone or 07953 966250 from another phone.
  • Open everyday from 8am - 6pm.
• In-store: Pop in to your nearest EE store and give them your PAC code.

EE will then handle the transfer of your number.

Important Notes:

• Remember to give your PAC code to EE within 30 days of receiving.

4. Wait for your number transfer to EE to complete

That's it you've done the hard work, now sit back and relax. EE will notify Tesco Mobile of your intention to leave and take your mobile number to EE.

The number transfer process will usually take 1 to 2 working days. After this time your Tesco Mobile mobile number will be working on the EE SIM card.
