BT Mobile is back, but only for BT Broadband customers

Last reviewed: 10 July 2026

What actually relaunched, and when

BT Mobile stopped accepting new customers in October 2023 as BT Group concentrated its consumer mobile efforts on the EE brand. That changed on 20 May 2026, when BT relaunched BT Mobile for new sign-ups at a press event inside Wembley Stadium, fronted by chief executive Allison Kirkby, alongside a wider push including a redesigned MyBT app and a new Wi-Fi 6 Smart Hub 3 router for broadband customers. This article is being published nearly seven weeks after that relaunch date rather than in the days immediately following it, unlike most launches covered on this site; the pricing and mechanics below remain current and unchanged since the 20 May relaunch, verified directly against BT's own live pricing page, but readers should treat this as a still-current cost breakdown of an existing product rather than breaking news of something that just happened.

The catch in the eligibility rules

BT Mobile's relaunch comes with a structural limitation that shapes who it is actually useful for: the service is exclusively available to existing BT Broadband customers. There is no standalone route to sign up for a BT Mobile SIM without already holding a BT Broadband contract, a deliberate positioning choice BT has described as making BT Mobile "complementary" to EE rather than a competing standalone brand. Customers wanting mobile-only service, or unlimited data and handset bundles, are directed to EE, which remains BT Group's primary consumer mobile brand and offers a broader plan range including pay-monthly handsets that BT Mobile, currently physical-SIM-only with no eSIM option and no handset deals, does not.

What the four plans actually cost

BT's own pricing page confirms four tiers, all 30-day rolling SIM-only contracts with no 12 or 24-month lock-in: 10GB at £9 a month as an introductory rate, reverting to £11 standard; 15GB at £13 a month; 30GB at £15 a month; and 75GB at £18 a month, which also includes 50GB of EU roaming rather than the smaller fair-use roaming allowance on the lower tiers. Every plan includes unlimited UK minutes and texts and BT's Scam Threat Protect feature, which screens and labels suspicious calls before they are answered, comparable to EE's own Scam Guard feature, though EE charges around £2 a month for a more comprehensive version that also includes mobile antivirus and ransomware protection, which BT Mobile's included version does not.

Prices per bt.com/mobile, July 2026. Halo broadband add-on customers receive double data on any tier. All plans are 30-day rolling with no long-term contract.

How the pricing compares against buying EE directly

Because BT Mobile runs entirely on EE's network, coverage and signal quality at any given postcode are identical to a SIM bought directly from EE. The comparison that matters is therefore price and terms rather than network quality. EE-network MVNOs such as 1pMobile and Lycamobile typically undercut BT Mobile's headline prices for equivalent data allowances, and EE's own direct SIM-only deals are open to anyone regardless of broadband provider, which BT Mobile is not. The genuine advantage BT Mobile offers is consolidation: a single bill alongside existing BT Broadband, the Halo double-data bonus for broadband customers on that add-on, and BT's own contact centre handling both services together, rather than a lower headline price. A household not already committed to BT Broadband has little reason to choose BT Mobile over a cheaper EE-network MVNO or EE directly.

Who the relaunch actually serves

The eligibility restriction makes BT Mobile's real audience narrow and deliberate: existing BT Broadband customers who want a single supplier relationship and value the Halo double-data bonus and combined billing over chasing the cheapest headline mobile price. For that specific household, the relaunch genuinely adds a mobile option that did not exist between October 2023 and May 2026. For anyone not already a BT Broadband customer, the relaunch changes nothing, since the product remains inaccessible regardless of how competitive its pricing looks on a comparison table.

The security features worth understanding

Scam Threat Protect, included on every BT Mobile plan at no extra cost, works at the network level to identify and label suspicious incoming calls before a customer answers, drawing on BT's own call pattern data across its broadband and mobile customer base. This differs from device-level scam apps in that it requires no separate download or setup; protection is active as soon as the SIM is activated. The gap against EE's paid Scam Guard tier is specifically in malware and ransomware protection rather than call screening, meaning a BT Mobile customer particularly concerned about malicious links or app-based threats, rather than nuisance calls, may still want a separate security app rather than relying on the included feature alone. For most everyday scam call and text screening, the included protection covers the most common threat pattern without an added monthly cost to the customer, and it sits alongside the free Cyber Threat Protect security suite BT also introduced for broadband customers as part of the same May 2026 announcement, extending the same protective framing across both services.

Frequently asked questions

When did BT Mobile relaunch for new customers?

20 May 2026, at a press event in Wembley Stadium, after being closed to new sign-ups since October 2023.

Can anyone sign up for BT Mobile?

No. BT Mobile is exclusively available to existing BT Broadband customers. There is no standalone way to get a BT Mobile SIM without a BT Broadband contract.

How much do BT Mobile's plans cost?

Four tiers: 10GB at £9 a month introductory (£11 standard), 15GB at £13, 30GB at £15, and 75GB at £18 a month, which includes 50GB of EU roaming.

Which network does BT Mobile use?

The EE network, which BT Group has owned outright since 2016. Coverage and signal quality are identical to a SIM bought directly from EE.

Is BT Mobile cheaper than buying EE directly?

Not necessarily on headline price. EE-network MVNOs such as 1pMobile and Lycamobile often undercut BT Mobile's rates, and EE's own SIM-only deals are open to everyone. BT Mobile's advantage is consolidated billing and the Halo double-data bonus for existing BT Broadband customers, not the lowest price.
