Is BT Mobile a good network?

BT Mobile is a superb network. It uses EE’s award-winning network to ensure the very best coverage in the UK and access to some of the fastest speeds around.

In fact, as of late 2022, all BT Mobile SIM-only plans have been rebranded as EE SIM-only plans. You’ll still get access to a wide range of contracts and great perks, just with a different brand name.

It’s worth noting. though, that while the network itself is impressive, its SIM-only plans are significantly more expensive than those of smaller networks such as iD Mobile and SMARTY.

What SIM-only deals can I get from BT Mobile?

BT Mobile SIM-only deals now offer the same plans as EE SIM-only, with one month, 12 month and 24 month deals all available.

There are simple deals offering just 1GB of data, right through to unlimited offerings for those who want or need to stay connected constantly.

You can get 4G and 5G SIM-only deals, while most plans also come with Stay Connected Data which keeps you online even after you’ve used your allowance, and the ability to gift data to other members of your household.

What benefits does BT Mobile offer?

There are a string of great benefits with BT Mobile SIM-only, now sold under the EE brand. These include:

  • Stay Connected Data - EE offers slower 0.5Mbps connections for when you run out of data, so you can still text using WhatsApp and check email
  • Gift data - If you have two or more plans on your account you can move data between them. Great for families and larger households
  • Ultrafast speeds on top end plans, ideal for gaming and streaming video
  • Smart Benefits - more expensive plans come with Smart Benefits, offering inclusive access to services such as Netflix, Apple Music, BT Sport, XBox Game Pass, endless entertainment streaming and Microsoft 365

Can I use my BT Mobile SIM abroad?

Unfortunately, new BT SIM-only customers will be using EE’s service, which has been subject to roaming charges since 2021.

Those on a deal taken out after 7 July 2021 will have to pay a daily fee to access their calls, minutes and data.

However, if your deal includes a Smart Benefit, you can opt to have data roaming included.

This puts BT Mobile/EE well behind rivals such as iD Mobile, which includes roaming in Europe for no extra charge.
