BT Mobile has a lot going for it, including higher speeds than most networks and slightly better 4G coverage.
Both of those points are largely down to the fact that it uses EE's 4G network (which it also owns), as that network is bigger and faster than its main rivals.
But there are also reasons you might want to choose BT over EE. For example, it offers discounts to BT Broadband customers. That said, it doesn’t do everything perfectly.
With that in mind, we’ve crafted this review of BT Mobile, highlighting the areas where it excels and those where there’s room for improvement.

BT Mobile uses the same core network as EE, giving it excellent coverage across the UK with 99, 98 and 99 per cent 4G, 3G and 2G coverage respectively. That puts it in a strong position when it comes to coverage, but you also benefit from access to BT's WiFi hotspots across the UK.

As you can see in the coverage comparison above, BT is ahead of rivals, other possibly than Three, but not by much, as Vodafone and O2 both have almost as much 4G population coverage.
Locations with 4G coverage include but are not limited to the following cities:
Aberdeen, Armagh, Bangor, Bath, Belfast, Birmingham, Bradford, Brighton, Bristol, Cambridge, Canterbury, Cardiff, Carlisle, Chelmsford, Chester, Chichester, Coventry, Derby, Derry, Dundee, Durham, Edinburgh, Ely, Exeter, Glasgow, Gloucester, Hereford, Inverness, Kingston upon Hull, Lancaster, Leeds, Leicester, Lichfield, Lincoln, Lisburn, Liverpool, London, Manchester, Newcastle, Newport, Newry, Norwich, Nottingham, Oxford, Peterborough, Peterlee, Perth, Plymouth, Portsmouth, Preston, Ripon, Sheffield, Southampton, St Albans, St Asaph, St David’s, Salford, Salisbury, Stirling, Stoke, Sunderland, Swansea, Truro, Wakefield, Wells, City of Westminster, Winchester, Wolverhampton Worcester and York.
BT Mobile launched its 5G service on October 11th, 2019, making it the first UK MVNO to do so. In fact, that even put its 5G mobile launch ahead of O2 or Three (the latter of which already offered 5G, but only for home broadband).
It's available in the same places as EE, which means 50 towns and cities in total at the time of writing. These include:
Ashton Under Lyme, Belfast, Birmingham, Bristol, Cardiff, Castlereagh, Chatham, Clifton, Coventry, Dudley, Edinburgh, Gillingham, Glasgow, Grays, Guildford, Hamilton, Harlow, Hoddesdon, Huddersfield, Hull, Kimberley, Kingston-upon-Thames, Leeds, Leicester, Lichfield, Lisburn, Liverpool, London, Maidstone, Manchester, Milnrow, Newcastle, Northampton, Nottingham, Oldham, Potters Bar, Rochdale, Romford, Salford, Sheffield, Solihull, Stevenage, Sunderland, Sutton Coldfield, Sydenham, Wakefield, Walsall, Watford, West Bromwich and Wolverhampton.
The chart below highlights the key places BT 5G is available in now, and where it’s coming to next.

As the chart above shows, there are nine locations confirmed to be getting 5G from the network in 2020, but expect plenty more to get it beyond those.
Note that 5G coverage isn't comprehensive in the places that currently have it. The focus is mostly on the busiest areas, but coverage will continue to improve.
As for BT's 5G speeds, the network has said to expect average speeds of around 150Mbps more than 4G, with peak speeds apparently able to reach 1Gbps. Note however that at the time of writing, BT 5G is only available to BT Halo customers.
BT mostly uses standard 4G, which is roughly 5 times faster than a standard 3G network. However, it also has an Extra Speed service as an optional extra, which reaches speeds of up to 60Mbit/sec.

According to an OpenSignal report from late 2019, EE’s average 4G download speed is 33.7Mbps. BT’s speeds aren’t part of the report, but they’re likely to be similar to EE’s, meaning probably higher than any major rival. The same applies to EE’s average 4G upload speed of 8.9Mbps.
EE’s average latency meanwhile is 37.3ms. That’s the measure of how long the network takes to respond to a request, so a lower number is better here, and EE (and likely by extension BT) is once again in the lead.

BT Mobile uses the 800MHz band, 1800MHz band, 2100MHz band and 2600MHz band for 4G. The 800MHz band is long range, making it a great fit for countryside locations, but it can also penetrate walls, for good indoor coverage.
The 2600MHz band on the other hand is shorter range but higher capacity, which means it can deal well with congested areas like inner cities. The 3400MHz band is even shorter range and is used for 5G. The 1800MHz and 2100MHz bands are somewhere in the middle.
For more in depth information, check out our 4G frequencies guide.
BT is seemingly mostly now looking to expand its 5G coverage across the UK.
BT Mobile doesn’t have any speed restrictions, no matter how much you upload or download, even at peak hours. BT Mobile also won’t slow down peer to peer file-sharing, so you’re free to use the network however and whenever you want without being slowed.

BT Mobile offers a range of Pay Monthly and SIM Only plans, which are detailed below. Note that they all include free use of BT’s 5 million+ Wi-Fi hotspots, and many of them support Family SIM, which lets you add additional SIM cards to the contract at a reduced price, each with its own data, and each additional one only being tied into a 30-day contract.
All of BT’s plans come with 4G at no extra cost. The network also now offers a number of 5G plans on Pay Monthly - so these are only available alongside a 5G phone and currently only for BT Halo customers.

BT Mobile’s Pay Monthly plans are all 24 months long and all allow you to use your data allowance towards tethering. You can get up to 100GB of monthly data with Pay Monthly plans.
BT’s SIM Only plans are all 12 months long and come with up to 100GB of monthly data. As with Pay Monthly, you can use any or all of that data for tethering. SIM Only plans also allow you to switch your allowance each month, so while you’re tied into a contract for 12 months you don’t have to stick with the same allowances.
Note that those 100GB max allowances can be exceeded but only if you're a BT Halo customer. In that case you get the option of unlimited data.
Highlights of BT Mobile’s plans include free access to BT Sport on many plans, and discounts if you’re a BT Broadband customer. There are also extras, detailed below, however data limits (outside Halo) are middling given that many networks now offer unlimited data for all.
BT also offers Data Only plans. These come on 12-month contracts with up to 30GB of data.
BT Mobile doesn’t currently offer any Pay As You Go plans.
BT's Extra Speed service is available as an optional add-on (though it comes as standard with some plans), doubling 4G speeds to up to 60Mbps. It's available in many of the same places as standard 4G. This is the equivalent of EE’s double speed service (which now comes as standard on that network) and isn’t as fast as EE’s 4G+ or 5G.
BT Mobile lets you use as much of your monthly data allowance as you want for tethering, so you can get tablets, laptops and other devices online by sharing your phone’s network connection. The only limit is your data allowance.
Wi-Fi Calling refers to the act of calling and texting over a Wi-Fi network, while using your normal number, dialler and SMS app, so it’s completely seamless. BT Mobile offers this to all new and existing customers, but currently you need an iPhone 5S or later, or a select Android handset bought from BT, including the Samsung Galaxy S10, OnePlus 7, Huawei P30 and more.
VoLTE stands for Voice over LTE (sometimes called 4G Calling) and lets you make and receive calls over 4G, so you’ll be able to stay in touch in places that don’t have a 2G or 3G signal. BT Mobile offers this to all customers, but at the moment it only works on the iPhone 6 or later, or a number of Android phones bought from BT, including the Samsung Galaxy S10 Plus, Google Pixel 4, Oppo Reno 5G, and others.
BT Mobile lets you use your full allowance of minutes and texts at no extra cost in 47 European destinations. You can also use your data, but above 15GB a surcharge may be applied. The applicable destinations are as follows:
Austria, Belgium, Bulgaria, Canary Islands, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, French Guiana, Germany, Gibraltar, Greece, Guadeloupe, Guernsey, Hungary, Iceland, Ireland, Isle of Man, Italy, Jersey, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Martinique, Mayotte, Monaco, Netherlands, Norway, Poland, Portugal (Incl. Azores & Madeira), Reunion, Romania, Saint Barthelemy, Saint Martin, San Marino, Slovakia, Slovenia, Spain, Sweden, Switzerland, and Vatican City.
BT Mobile also offers a Travel Data Pass, which lets you use 500MB of data for £6 each day in Andorra, Australia, Canada, China, India, Mexico, New Zealand, South Africa, Thailand, Turkey, UAE, and the US.
While hard to judge conclusively, one report suggests BT’s customer service may leave something to be desired.
According to an Ofcom service quality report from late 2018, 33 of every 100,000 customers found reason to complain about BT to Ofcom. That may not sound like many, but of the networks on test only Virgin and Vodafone performed worse, with the average being just 18.
Overall BT Mobile is a good network choice, but exactly how good depends on your needs. By leveraging the power of EE’s infrastructure BT has one of the fastest 4G networks around – especially if you opt for its Extra Speed service, and if you’re a Halo customer you can even get 5G and unlimited data.
But it has also got benefits of its own, such as free access to BT’s extensive network of Wi-Fi hotspots, along with Wi-Fi Calling and 4G Calling on select handsets.
It's not an all-rounder - its offerings feel slightly limited, as there’s no Pay As You Go. BT also isn’t as competitive for roaming as some rivals, and its customer service record doesn’t look great, but if you’re happy to have a contract and will mostly be using your phone in the UK it’s a strong option.
