BT Mobile — New Customers Logo

Switch to a BT Mobile SIM-only or mobile phone plan today and benefit from their excellent UK coverage and free BT Wi-Fi hotspots, as well as free extras like the BT Sport app on some plans. BT Mobile’s SIM-only plans start from just £13 per month, and for this price you’ll get 4GB of data as well as unlimited minutes and texts.

Or, if you regularly use the internet or stream videos, games and music, you can get as much as 100GB of data included on your plan. Your monthly payments will also be cheaper if you select a longer, two-year contract, so if you’re happy to commit to a longer mobile package, you’ll end up saving yourself money each month.

There are a whopping five million BT Wi-Fi hotspots across the UK. In fact, BT Mobile has 4G and Wi-Fi available in more parts of the country than many other providers, including O2, Vodafone and Three. It’s easier than ever to stay connected thanks to BT Mobile, particularly as all of their mobile plans come with unlimited minutes and texts. BT Mobile phone contracts also start from just 12 months in length, which is great for customers who don’t like being tied down to lengthy contracts.

Whether you’re interested in the latest Apple iPhone or a Samsung Galaxy S21, you can get a handset mobile phone plan by choosing one of BT’s EE-affiliated plans, or you can opt to buy a handset upfront from the BT store. Compare iPhone SEs against the Samsung Galaxy S20 FE, and find the best device for you.

Get 4G calls and Wi-Fi calling with BT Mobile, as well as inclusive data roaming in 47 destinations across the world. If you’re a new BT Mobile customer, you can easily switch over and keep your old number, and BT have their customer service team on hand to help if you get stuck at any point. Plus, if you’re already an existing BT Broadband customer, you can access some fantastic freebies and discounts if you sign up to a BT mobile contract too.

Before you go browsing the BT Mobile offers on their website, make sure you sign up to TopCashback and shop with us so you can make the most of our amazing cashback rates.

Mobile plans for the whole family

Get the whole family connected with one of BT’s family SIM plans. With every monthly SIM you add to your family plan, you’ll get an impressive 20% discount on the price of that SIM. There’s a helpful breakdown of how this discount works on the BT Mobile UK website too.

The great benefit to this BT Mobile deal, aside from the generous discount, is that you can keep tabs on all your family’s SIMs (including settings, usage and payments) on one account. You can also add or remove additional SIMs at any time, so it’s really flexible and perfect for busy families. Download the BT Mobile app and you can use their parental controls to protect your family when they’re online as well.

You can choose for all your SIMs to have an allowance of 4GB, 8GB, 12GB, 25GB, 40GB or 100GB of data, and all come with unlimited calls and texts. And don’t worry, if you change your mind within the first 30 days of your new plan, you can cancel it and get a refund of your first bill.
