This add on is valid from the moment you buy it and then runs on a 30 day rolling contract with no minimum term.

Full details

With Extra Speed, the maximum speed available through the network is capped at 60 Mbps rather than 30 Mbps on our standard 4G. The speeds you get on your phone will be lower, and depend on things like the number of users, distance from the mast and the type of 4G phone you have. This add on is valid from the moment you buy it and then runs on a 30 day rolling contract.

Extra Speed is not available on BT Business Mobile plans.

International roaming extras

Going abroad? Either pay as you go with our standard roaming rates, or get a data roaming add-on.

Add Roaming data


When using data abroad, you can pay our standard roaming rates to stay in touch, or take one of our data roaming add-ons.

Our new lower standard roaming pricing for countries in the EU zone means you'll pay less to use data as you go, so you can stay in touch wherever you are.

If you're a regular roamer, or need lots of data, you can add more and relax about how much you're online when in Europe and the USA by taking one of our data roaming add-ons.

* For existing mobile customers. Add-ons run on a 30 day rolling contract until you cancel them. When you first buy an Add-On, it lasts until the date of your next BT Mobile bill. It covers minutes or data used over your inclusive plan allowance, up to the allowance for that Add-On, from your last BT Mobile bill until your next one. Add-On allowances reset at the start of each billing month. Add-Ons can only be used in the UK. You can only have one data and one minutes Add-On at any one time.
Full Terms

Full terms

  1. Any BT Mobile customer can buy UK Add-Ons.
  2. A UK Add-On covers minutes or data used over your inclusive plan allowance, up to the allowance for that Add-On, from your last BT Mobile bill until your next one. (So if you buy a 500MB Add-On 10 days before the date of your next bill, it'll cover the data you use for those days and the previous 20).
  3. The add-on renews automatically every month on the date you get your BT Mobile bill, unless you cancel it. If you don't want your UK Add-On to renew automatically, you'll need to contact us to cancel it before the date of your next BT Mobile bill. (You can still carry on using it until the date of your next bill and we won't charge you again).
  4. Any unused allowance won't carry over when your billing month ends. And if you go over your allowance, standard charges will apply.
  5. You can only use UK Add-Ons in the UK. You can have a maximum of one for minutes and one for data at any one time.
  6. We won't transfer or refund UK Add-Ons. They're for your personal use and subject to BT Mobile Service terms and conditions.
  7. These terms and conditions are subject to change, but we'll tell you if we make any changes that would significantly disadvantage you.

Frequently asked questions

Family SIMs could be the perfect solution for you and your family. The more SIMs you add to your account, the more you save. Everytime you add a SIM, you get a bigger monthly discount.

You can choose to add family members or friends to your plan or get the benefit yourself by adding SIMs you might have for different devices.

You can add up to five Family SIMs to your account. You become the main account holder and are responsible for all charges.

    It's easy, just order your SIMs from

    If you know someone who already has a BT Mobile SIM, you can invite them to move to your Family SIM. Find out how to invite someone.

      The overall cost depends on how many SIMs you have in the plan. The cost for each one gets lower the more you add. So the first SIM is the same rental price as a single SIM only plan, the second has a lower rental price, the third lower still and so on. Offers may vary.

        To keep track of your SIM usage, allowances and settings, just go to

          Family SIMs have more flexible contract terms than standalone SIMs. When you add a Family SIM to an existing SIM Only plan, a new 12 month minimum term begins. All SIMs will have a 30-day rolling contract. If the plan ends up with just one SIM left, that will pick up what’s left of the 12 month minimum term
