How good is BT Mobile?

Before signing up for a new phone deal, read our review of BT Mobile to see how it did in our regular mobile phone satisfaction survey.

In our latest survey, we spoke to more than 3,900 real customers from 15 of the biggest phone providers, including EE, O2, Vodafone and Three. They told us exactly what they thought of their phone company, from the customer service on offer to the value for money they get.

In this in-depth review of BT Mobile, we'll:

  • give you a full breakdown of how its customers rated it for key factors, including customer service, value for money and incentives.
  • report quotes from real BT Mobile customers on their experiences.
  • tell you whether it's a Which? Recommended Provider.

Only logged-in Which? members can view the results in the table below. If you’re not yet a member, you can get instant access by joining Which? today.

What network does BT Mobile use?

BT Mobile uses EE. BT Mobile is a virtual provider, which means it uses another provider's infrastructure – in this case EE's. It offers 3G, 4G and 5G coverage.

BT Mobile's deals

BT Mobile mainly sells Sim-only deals that you use with your own handset, although it does also sell a small range of smartphone contracts.

You can also add bundles of extra data or minutes and can pay more to get faster 4G download speeds (up to 60Mbps rather than 30Mbps) although this is now free with any 10GB plan or higher.

You don't have to have a BT broadband deal to take out one of its mobile packages, although broadband customers do save £5/month on their mobile deals, and if you have BT Halo you can get extra data added to your plan.

Find out how customers rate BT as a broadband provider.

Families can add up to five Sim cards on the same plan with BT's Family Sim scheme. The more Sim cards you add to the package, the more you save (eg one Sim card on BT's 5GB plan costs £14/month, two Sim cards cost £21, three cost £28, etc), and because each Sim can have its own individual allowance, you don't have to worry about sharing data across your entire family.

Customers can also make free use of BT's five million wi-fi hotspots and can avoid nasty bills by capping their monthly spending. 

Compare the best BT Mobile Sim-only deals and see how much you could save. 

BT Mobile stores

BT Mobile doesn't have its own stores.

If you need any help or advice, you can get it via its website or by calling BT customer services on 0800 800 150 (or 150 from your BT Mobile).
