There are so many options with BT Mobile – and this can be overwhelming. That’s why we’ve put together this comprehensive guide to help you find the best BT Mobile phone deals and learn about BT Mobile’s coverage and customer service too.


Why choose BT Mobile?

As you’d expect from BT’s mobile brand, BT Mobile certainly offers an impressive and extensive range of plans and features. It’s important to note first and foremost that BT Mobile is one of the more expensive carriers in the mobile market – but few competitors can boast the same speeds, and they certainly can’t offer the same bonuses.

BT has many broadband customers across the UK, so if you’re already with BT broadband, you can get a £5 discount on any BT Mobile plan – including those including handsets. You’ll also get access to over five million BT free Wi-Fi hotspots across the country, allowing you to stay connected without using up any data. And, if that wasn’t enough, you can even get free access to the BT Sport app with select BT Mobile plans – which is a great perk for avid football fans.

As BT Mobile uses the EE network, you’ll also get excellent UK-wide coverage. And, if you need to go beyond the UK, there’s also EU roaming at no extra charge, so you can keep connected abroad without breaking the bank. Overall, you’ll certainly get a reliable mobile experience from this provider, and there are plenty of perks to sweeten the deal.

BT Mobile coverage

BT is a mobile virtual network operator (MVNO) – which means it piggybacks on another network’s infrastructure. BT Mobile uses EE’s mobile network, so it offers the same coverage as EE does. This means that over 99% of the population can access 4G services via the EE network (and therefore BT Mobile), so you can expect coverage pretty much anywhere.

Did you know...

EE, part of the BT Group, runs the UK’s biggest and fastest mobile network, offering 4G in more places than any other UK network.

Currently, BT Mobile’s 5G coverage is limited, but always expanding. Over 193 UK towns and cities can connect to 5G services via BT Mobile network.

To find out whether you can receive 3G, 4G, or 5G coverage from BT Mobile, use the provider’s online coverage checker.

BT Mobile contracts and pay-monthly deals

Mobile phones are rather expensive, with the latest models from major brands costing hundreds if not thousands. Purchasing these devices upfront isn’t an option for many customers – but unfortunately, BT Mobile doesn’t offer any handset plans.

However, as BT and EE are now part of the same family, BT Mobile refers its customers to EE’s range of pay-monthly phone plans.

BT Mobile Family SIM deals

BT Mobile offers a rather unique service with its Family SIM plan. This allows you to join one plan with up to five SIM cards – so your family can stay connected with one contract. Each SIM is on a 30-day contract, so any plan member can cancel their individual contract whenever – offering total flexibility.

You can choose how many SIM cards and how much data you want, and these variables will affect the monthly cost. BT Mobile allows you to choose two, three, four, and five SIM cards per plan, and the data allowances are 4GB, 8GB, 12GB, 25GB, 40GB, or 100GB.

BT Mobile key features

BT Mobile isn’t one of the cheapest providers, but it offers plenty of appealing features – some of which you won’t find elsewhere. These features can really help justify choosing BT Mobile over its competitors. Here the most attractive ones:

  • £5 per month discounts on mobile plans if BT is your broadband provider
  • family SIM plans to save money and cover multiple SIMs in one contract
  • access to over five million BT Wi-Fi hotspots across the country
  • BT Sport app included for free in some plans
  • extensive coverage with 5G via EE’s network
  • support for Wi-Fi calling
  • roam like home across Europe.


BT Mobile speeds

BT Mobile offers faster mobile broadband speeds than most of its competitors. The EE network supports 4G like the other major networks, but it offers faster speeds than most – and BT Mobile customers can take advantage of this.

The average download speed you can expect from BT Mobile, considering its 3G, 4G, and 5G connectivity options, is 44Mbps. This is twice as fast as the average download speeds from Vodafone and O2, and almost double Three’s average speeds too. You’ll also receive average upload speeds of 9.7Mbps with BT Mobile – which is pretty impressive.

BT Mobile data and calling features

One attractive feature of BT Mobile is 4G and Wi-Fi calling. Naturally, this involves making or receiving phone calls over the Internet, rather than a traditional phone signal.

Any phone with a BT Mobile SIM card is ready to take part in 4G or Wi-Fi calling. Your device will connect to the Internet via 4G or Wi-Fi wherever possible, and phone calls will rely on the Internet – which results in better call quality. The best part is that you’ll be charged your standard network rate, and you can stay connected in areas with poor coverage.

BT Mobile roaming features

BT Mobile plans support a ‘Roam Like Home’ approach to using your phone abroad. This scheme basically means you can use your handset in 47 destinations – mainly within the EU – without paying additional roaming charges. Instead, you’ll just use your standard allowance of calls, texts, and mobile data at the usual UK rate.

Note that calls or texts to non-UK numbers aren’t covered under Roam Like Home, so you can still expect to pay BT Mobile’s international calling rates. You can visit BT Mobile’s roaming page to see which countries support roaming at no extra cost.


Person dialling their phone

BT Mobile customer service

Customer service is an important aspect of any provider. Whether you’re having billing issues or struggling to make calls, it’s handy to have the support of a decent customer service team – but how does BT Mobile perform in this sense?

Does BT Mobile have good customer service?

BT Mobile’s customer service seems to be of a rather high standard – and of a better quality than most carriers offer. Although Ofcom has not yet provided an overall customer satisfaction score for BT Mobile, the carrier found that for every 100,000 customers, there were only eight complaints made to Ofcom. This is lower than the industry average of 10, which is promising for BT Mobile.

BT Mobile also had the second shortest call waiting time of any mobile provider, with customers usually waiting just 55 seconds. However, Three offers even shorter waiting times, averaging just 16 seconds.

BT Mobile reviews

On the review aggregator site Trustpilot , BT Mobile has a score of 1.6/5 stars based on over 11,000 reviews. Trustpilot considers this ‘Bad’ – suggesting that most BT Mobile customers aren’t satisfied.

Here is an example of a happy BT Mobile customer who left a five-star review:

“I am giving 5 stars solely on customer service after being tended to by the live chat agent: Sayantani. They made me feel heard and my problems were resolved.” -Jane Levinston

Unfortunately, most customers aren’t so pleased, as shown by this one-star review:

“Stay clear of BT as they are overcharging for all their services. Go elsewhere if you can.”-Louise Velma

How can I contact BT Mobile customer service?

The easiest way to contact the customer service team at BT Mobile is by calling 0800 800150 – or just 150 from a BT Mobile device. The support team is available from 8am to 9pm on weekdays, or 8am-8pm on weekends.
