BT Mobile is back in the UK from Wednesday (20 May), exclusively for BT Broadband customers.
The relaunched service offers four 30 day rolling SIM only plans, starting at £9 a month for 10GB on an introductory price (rising to £11), then £13 for 15GB, £15 for 30GB and £18 for 75GB.
All plans include unlimited UK minutes and texts, network-level scam call screening branded as Scam Threat Protect, and inclusive EU roaming, with the 75GB plan capped at 50GB of roaming use under fair use rules.
Households on a Halo 3 or Halo 3+ broadband package get double their monthly data at no extra cost.
BT Mobile closed to new customers in October 2023, when BT Group accelerated a strategy to make EE its flagship consumer brand. Group Chief Executive Allison Kirkby reversed that position, and BT confirmed the relaunch at a Wembley Stadium press event on 7 May alongside its appointment as the official telecommunications partner of UEFA Euro 2028.
Under new CEO Allison Kirkby, the group has shelved parts of that plan to avoid alienating loyal (particularly older) customers and is now embracing a clearer multi-brand approach:
- BT – Core heritage brand for broadband, landline and now mobile bolt-ons.
- EE – Flagship for premium mobile, handset deals and unlimited data.
- Plusnet – Remains focused on basic, no-frills broadband and landline services.
The refreshed strategy will be backed by BT’s biggest marketing campaign in a decade, the group said.
The plans run on the EE network, which BT says topped the H2 2025 RootMetrics UK RootScore report for overall performance. Scam Threat Protect uses network level call labelling to flag suspected nuisance or fraud numbers before the user answers, and takes up to 72 hours to activate.
The same screening already sits on EE, where it is sold as part of a £2 monthly add on rather than included by default.
The advertised prices apply only to households with an active BT Broadband connection on the same account; anyone signing up without one pays £5 more a month.
Monthly charges assume online billing, and a £2.50 annual price increase applies to all mobile plans on 31 March each year.
EE retains handset bundles, unlimited data allowances and longer contract terms for BT Group customers who want them. BT pitches BT Mobile as the lower volume option for broadband households that want a single bill and a single account login.
