Getting ready to upgrade
To make sure your upgrade is as easy as possible, here are some helpful tips on how to prepare
Check your log-in details to access your account
To log in and upgrade, you’ll need your username and password. You chose these when you bought your contract, and you’ll find your username in your order confirmation email. Forgotten your username and/or password? No need to worry. Just click here and we’ll help you get logged in.
See when you can upgrade
You can find out if you can upgrade by logging in to My Account or by checking on our Tesco Mobile app. You’ll need to log in using our 2-step authentication process to see your full list of options, so make sure you have your phone handy, as we’ll need to send you a pin to log in, after you’ve provided your username and password.
If you’re looking to upgrade before the end of your contract, you may have to pay an early upgrade fee. Just click here to find out when early upgrade fees apply.
You won’t be able to upgrade if you’ve upgraded or changed your tariff in the last month, or if you haven’t paid your recent bills.
Make sure your billing address is up to date
Once you’re logged in to My Account, it’s important to check that your billing address is up to date. To make sure you’ll be able to upgrade, please update your address at least 72 hours beforehand.
Check if you’ll need to swap your SIM
If your new phone takes the same size SIM as your current phone, you can simply pop your old SIM in, and you’ll keep your same number.
If your new phone comes with a different size SIM or you need to change to or from an eSIM, you’ll need to swap your SIM. (You might hear it called ‘doing a SIM swap’.) This is easy to do, and it means you’ll keep your same number. Just click here to find out how to swap your SIM.
