Why Choose a BT Mobile SIM Only Deal?

BT Mobile review banner

BT Mobile is a great all-around network operator, offering great 4G network coverage and the fastest 4G data speeds. The carrier also provides 5G at no extra cost to their customers, provided their phones support 5G. BT Mobile uses the EE network, which means both networks offer identical coverage and speeds across the UK.

The network also allows you to use BT WiFi for free, which gives you access to over 5 million BT WiFi hotspots in the UK. BT Mobile users can roam like home in 47 countries, increase or decrease their data allowance each month, get unlimited UK calls and texts, and there is a 30-day money-back guarantee. These deals also include 4G Calling and WiFi Calling.

The carrier’s family mobile plans also deserve a shout, as you can save up to 20% per SIM, however, you can only add a maximum of five SIMs on each family plan.

BT Mobile SIM Only Contracts

If you’re happy with the handset you have, you can choose a pay monthly SIM only contract from BT Mobile. Unfortunately, the network doesn’t have any no credit check SIM only deals. No matter which plan you choose, you have to undergo a credit check. We strongly recommend you to check out our extensive guide on how mobile credit checks work.

BT Mobile doesn’t offer any PAYG SIM only deals. At the moment, they have 12-month and 24-month contracts. On the bright side, you can switch between all the available SIM only deals once a month. Existing BT Broadband customers get a £5 discount a month on all deals. If you also have BT Halo, the network will double your data. The 12-month 100GB data plan turns into an unlimited data plan with BT Halo.

BT Mobile 12-Month Contracts

The network’s 12-month contracts are a little pricier than their 24-month counterparts, but they’re obviously the better choice for testing the water. The deals you find on each party may differ slightly, and BT updates its offers on a regular basis. You can’t switch between 12-month plans and 24-month plans.

BT Mobile 24-Month Contracts

These BT Mobile SIM only contracts work exactly the same as their 12-month counterparts. The only difference is they lock you in with the network for a longer term. Two years is quite long in terms of SIM only deals, but BT Mobile lets you switch between plans monthly.

Just make sure you’re okay with committing to a long deal as cancelling your mobile contract can be tricky and you may end up having to pay a penalty fee for cancelling early. If you’re planning to switch your mobile network, you can keep your mobile phone number, so don’t let that stop you.

BT Mobile Phone Contracts

BT Mobile offers a very limited range of phones, but If you’re a BT Broadband customer you can get 10% off EE handset plans.

All phone deals are on a 24-month contract combined with a SIM deal. The exact monthly price will change depending on your handset and plan choice. Some of the handsets may require you to pay an upfront fee.

Since the network offers a Limited range of models for phones, you can find better deals with most UK mobile phone retailers. You may also want to have a look at refurbished phone deals, as some of these handsets can be in very good condition, and significantly cheaper than a new handset.
