1) Check you're eligible to switch from EE
If you're out of contract with EE, you can switch for no charge whenever you like.
Not sure if you're out of contract? To find out, you can call 150 from your EE phone to speak to customer support. Or on 07953 966 250 from any other phone (standard network charges apply).
Opening hours are 8am-8pm Monday-Friday. 8am-6pm at weekends.
Don't fancy phoning? Log in to your EE account online instead.
Keeping your old phone and signing up for a new SIM-only deal with a new network? Okay, that means there’s a chance you may need to get your phone unlocked.
The good news is that this is very simple. Just head to EE’s site where you’ll find a form to fill in to unlock your smartphone.
Once that’s done, they’ll provide you with a personal unlocking key (PUK) that you can use to unlock your handset.
And if you’re interested in switching but want a bit more information first, text INFO to 85075.
2) Contact EE to cancel your contract and get your PAC code
Once you’ve signed up for the deal you’ve chosen, just text PAC to 65075 to get your PAC code. It’s this short, alphanumeric code that will enable you to transfer your existing phone number to the network you want to join.
If you'd prefer to speak to somebody, just give EE a call, tell them you'd like to leave and request your PAC code.
EE is bound by law to provide a PAC Code within two hours of you asking for it.
3) Find and buy a deal from Tesco Mobile
Assuming you’re ready to switch, it’s time to select a deal from Tesco Mobile and sign up for it through Uswitch.
Tesco Mobile will, of course, conduct credit checks. But assuming you pass, you’ll then receive your phone in the post.
4) Contact Tesco Mobile to give them your PAC Code
Now you’ll need to contact Tesco Mobile and give them your PAC Code.
You can get in touch with Tesco Mobile’s customer support team on 0345 301 4455 (standard network rates apply).
Opening hours are 8am-9pm Monday-Friday. 8am-8pm Saturdays and 10am-6pm Sundays.
5) Insert your Tesco Mobile SIM
Okay, now it’s time to insert your Tesco Mobile SIM in your new phone, or in your existing phone if you bought a SIM-only deal.
You’ll find that the number won’t have transferred straightaway. But while the transfer’s underway, you’ll be given a temporary number. So you’ll still be able to use your phone.
6) Wait for your number to be transferred to Tesco Mobile
All being well and if a weekend doesn't get in the way, your number should be transferred the next working day. After which point, you’re good to go.
