You can get faster data speeds than our standard 4G
With our Extra Speed add-on, experience speeds of up to 60Mbps rather than up to 30Mbps on our standard 4G. That means you can stream video, download apps and upload pictures up to twice as fast*
This add on is valid from the moment you buy it and then runs on a 30 day rolling contract with no minimum term.
Available to all existing BT Mobile customers.
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.
Going abroad? Either pay as you go with our standard roaming rates, or get a data roaming add-on.
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.
It's easy to get more data and unlimited minutes – from as little as £4 a month.

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.
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.
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
*Family SIM saving compared to the same number of individual SIMs bought on our standard SIM Only plan.
ΔWe may change any prices and terms during your contract. If this affects you, we'll tell you about important changes in advance, and you'll be able to end your contract without any fees.
