The move towards a quad-play operation has seen the launch of BT Mobile and initially three SIM only plans are available.
BT Mobile 500 MB Plan, 500 MB of 4G data, unlimited texts and 200 minutes of calls. Unlimited BT Wi-Fi. £5 per month on a 12 month contract.
BT Mobile 2 GB Plan, 2 GB of 4G data, unlimited texts and 500 minutes of calls. Unlimited BT Wi-Fi. £12 per month on a 12 month contract.
BT Mobile 20 GB Plan, 20 GB of 4G data, unlimited texts and unlimited calls. Unlimited BT Wi-Fi. £20 per month on a 12 month contract.
The pricing above presumes you are an existing BT Broadband/Infinity customer. The plans are available standalone and cost £5 extra per month, but also give you access to BT Sport content via an app on the handset.
