BT Mobile is the only place where you can get the combined power of fast 4G and unlimited internet access on the UK's largest wi-fi network.

Be better connected, with 4G reaching over 90% of the UK population. And if you're not in a 4G area, we'll connect you to 3G or 2G instead.

BT mobile phone deals include:

  • Fast 4G and free BT Wi-fi on all plans
  • Choose from a selection of the most popular phones. All mobile phone plans come with free next day delivery
  • Unlimited 0800 calls, a monthly spend cap and free BT Sport Lite on your smartphone – available on all BT Mobile plans
  • Alternative SIM Only plans let you keep the phone you’ve got


In addition BT offers a range of features for all plans:

  • Avoid nasty surprise bills with monthly spend caps on all BT Mobile plans. You can set a cap when you’re abroad too, to help you keep a lid on roaming data costs. BT will send you a text when you've used most of your allowance
  • Download the BT Mobile app to keep tabs on what allowances you’re using and what you’ve got left. Check how much you’ve spent outside of your plan and find out where you spent it. See the details of your plan, when it renews and what settings you’ve got
  • When you go over and above your monthly allowance, BT will keep an eye on what you’ve used and text you if you’d be better off on the next plan up. If you do change your plan, you won’t have to start a new contract. If you’re constantly running low on your allowance, you can move up to a larger plan any time you want
  • Get online at more than 5 million BT Wi-fi hotspots in the UK. BT Wi-fi won't count towards your monthly data usage, and there's no limit to how long you can stay connected and how much you download. Download the BT Wi-fi app and your phone will connect as soon as you’re in range of a hotspot
