SMARTY Coverage Map
The easiest way to check SMARTY’s mobile coverage in your area is by using their online coverage map. Simply enter your postcode to see the 4G coverage and 3G coverage that’s available in your area.
We’d normally recommend using the online coverage map before you sign up and get a SMARTY Mobile SIM card.
You can use the tabs on SMARTY’s website to switch between the results for 4G and 3G coverage. Typically, we’d only recommend choosing SMARTY if you’re able to get good indoor coverage on their network.
SMARTY currently offers a choice of plans from £6/month. These include 14GB data for £8 per month and 30GB data for £10 per month. You can also get unlimited data on SMARTY for £20 per month. All of these plans give you full access to coverage on SMARTY’s mobile network, including 4G, 3G, Wi-Fi Calling and 4G Calling.

For more information, read on to learn more about the different types of coverage available on SMARTY.
SMARTY 4G Coverage
In the UK, SMARTY currently offers 99.8% population coverage on their 4G network. This offers download speeds of up to 300Mbps, but speeds of around 15-20Mbps are much more typical.
In recent years, SMARTY’s 4G network has been undergoing a major upgrade across the UK. This has led to a speed improvement of up to 130% in areas that have been upgraded with the new network. The upgrade consists of three major changes:
- The introduction of 4G+ technology. This combines multiple 4G frequencies to boost the speeds you can get on SMARTY’s network. This technology is also known as LTE-Advanced Carrier Aggregation.
- The upgrade of older 3G spectrum to 4G. This improves the utilisation of spectrum at 2100MHz so you’re able to get faster 4G speeds rather than 3G speeds.
- The introduction of L-Band spectrum. Also known as Super 4G+, this involves the addition of L-band spectrum within band 32 to further improve the speeds you can get on 4G.
To get the fastest speeds available on SMARTY, you’ll need a 4G device that’s compatible with L-Band coverage. This will normally be listed as “LTE band 32” on the manufacturer’s spec sheet.
SMARTY 4G Calling & Wi-Fi Calling
In addition to upgrading their 4G network, SMARTY also launched 4G Calling and Wi-Fi Calling to their customers during 2020.
- 4G Calling allows you to make and receive phone calls using Voice over LTE technology (VoLTE). This gives you a more reliable experience on phone calls as well as better quality HD Voice calls. In addition, you’ll also benefit from better coverage on 4G as this uses lower-frequency 800MHz spectrum.
- Wi-Fi Calling allows you to make and receive phone calls and text messages over a Wi-Fi connection. It means you can stay connected in places where a mobile signal isn’t able to reach (e.g. in the basement of a large building or when travelling on the London Underground).
4G Calling has been available to customers on SMARTY since May 2020. Meanwhile, Wi-Fi Calling has been available since November 2020. You’ll need a compatible device to benefit from the two technologies on your mobile phone.
SMARTY 3G Coverage
In addition, SMARTY also continues to offer 98.7% population coverage on 3G. This is also using Three’s 3G network and their 2100MHz spectrum.
You can get download speeds of up to 42Mbps on SMARTY’s 3G network, which uses dual-carrier HSPA+ technology. However, download speeds will more typically be in the region of 4Mbps to 8Mbps on 3G.
If your phone doesn’t support 4G Calling or Wi-Fi Calling, you’ll be using SMARTY’s 3G network to make and receive calls on your phone.
SMARTY doesn’t offer any 2G coverage. For this reason, it isn’t possible to use a SMARTY SIM card in an old mobile phone that’s restricted to 2G. In addition, a SMARTY SIM card may not work in some dual-SIM phones if the secondary SIM card slot is restricted to only supporting 2G.
Upcoming 5G Roll-Out
SMARTY have said that 5G will be launching on their network, but they haven’t yet set an exact date for when it will launch. Instead, they’ve said that the current focus is on improving their 3G and 4G service:
Great news. 5G will be coming to SMARTY.
But as these things take time to get right, we’re first going to be upgrading our network’s 3G and 4G services to ensure you have the best coverage possible.
We’ve introduced Voice over LTE (VoLTE) which lets you make richer, clearer voice calls over the 4G network – it’s essentially calling in HD.
We’ve also launched WiFi Calling to help supercharge your signal. So you can make calls and send texts wherever you’re connected to WiFi in the UK.
When 5G coverage eventually launches on SMARTY, they’ll also be using Three’s 5G network.
You can sign up for a waiting list for 5G on SMARTY’s website. Alternatively, if you’d like access to 5G today, you can get a SIM-only deal from Three instead. Three currently offer 5G at no extra cost on all of their plans with an average download speed of about 200Mbps.
If you’re travelling abroad to another country, it’s possible to continue using your SMARTY SIM card through international roaming.
For customers travelling to an EU destination, it’s possible to use your SMARTY plan allowances at no extra cost when travelling abroad. A fair usage limit of 20GB per month applies for European roaming, if your SMARTY price plan gives you more than 20GB of data per month.
If you’re travelling to a country outside the EU, you’ll need to top-up your SMARTY account with a cash add-on before you depart. You’ll then pay the international roaming rates listed on this page.
You should follow the instructions on this page to set up your phone for international roaming before you depart the UK.
