SMARTY 5G coverage checker

5G is available on Smarty Mobile in parts of at least 303 UK towns and cities at the time of writing. We know this as the company uses Three’s 5G infrastructure (and in fact is owned by Three), so its 5G coverage is identical.

Smarty Mobile launched its 5G service in January 2022, so it arrived quite a lot later than many other MVNOs (mobile virtual network operators), but not many use Three’s network to offer 5G.

You’ll find all the information you need on Smarty Mobile’s 5G network below, plus details on how it compares to other 5G networks.

How does Smarty Mobile's 5G coverage compare to others?

We keep track of which networks offer 5G coverage across 120 major UK towns and cities, so you can see at a glance how they compare in key locations. Currently that’s as follows:

  • O2 has launched 5G in 75 of the 120 locations below. 
  • Three (and therefore Smarty) has launched 5G in 85 of the 120 locations below. 
  • EE has launched 5G in 82 of the 120 locations below. 
  • Vodafone has launched 5G in 44 of the 120 locations below. 

For clarity, these are locations that a network claims to have 5G coverage in, however the amount of coverage can vary significantly, so it won’t always be widespread.

As such, it’s worth using a network’s official coverage checker to be sure it’s available in the places that matter to you.

4G coverage

While Smarty Mobile offers widespread and rapidly growing 5G coverage, there are still many places that don’t have 5G, and in these locations you’ll be reliant on 4G or 3G.

Thankfully, you should be even better served for coverage with those network technologies, as the chart below shows.

5G roaming abroad

You can’t roam using 5G on Smarty Mobile, but you can use 4G and 3G and if you’re in the EU then it comes out of your normal data allowance at no extra cost.

5G network speeds

Average 5G download speed

Median 5G download speed

Max 5G download speed

158.7Mbps (Point Topic)

130.1/122/231Mbps (RootMetrics/Point Topic/Ookla)

478.1Mbps (RootMetrics)

Smarty Mobile hasn’t yet spoken about the exact speeds of its 5G network and nor have there been any real studies into them, but since it’s both owned by Three and uses that network’s infrastructure, it’s likely that the two are very similar there.

For what it’s worth then, you’ll find an average UK 5G download speed of 158.7Mbps on Three, according to Point Topic data published in September 2020. The same report also pointed to a median 5G speed of 122Mbps and a maximum 5G speed of 473Mbps.

Elsewhere, data from Ookla (which runs Speedtest) captured in the first half of 2021 recorded Three’s median 5G download speed as being 231Mbps, and in Q3 2020, RootMetrics found that Three’s maximum 5G speed was 478.1Mbps.

RootMetrics came back in the first half of 2021 with a report saying that Three’s fastest median 5G download speed was 130.1Mbps, and that the network’s fastest median ‘everyday 5G’ (which combines both 5G-only readings and switching between 5G and 4G) was 127.1Mbps.

So while these speeds vary a fair bit, they’re all reassuringly high, especially when compared to 4G, with which Three offered average speeds of 22.2Mbps in October 2020, according to Opensignal. That data is older because not many tests look specifically at 4G speeds now.

5G speeds are likely to improve over time too, as infrastructure improves and additional spectrum gets acquired (or existing spectrum gets repurposed).

Latency

Latency is another important measure, as it shows how long a mobile network takes to respond to a request (such as loading a web page) before data starts moving to carry that request out.

This is typically a tiny amount of time, so it’s measured in milliseconds (ms), and while we don’t have any latency data for Smarty Mobile, we do know that according to Ookla the average latency on the UK’s 5G networks could range between 21-26ms.

But Three specifically has also had its 5G latency tested by RootMetrics, which found that in central London it was as low as just 17ms, which is lower than any other network in this test. That bodes well for Smarty Mobile.

For reference, latency averages around 30-50ms with 4G, and 5G latency is likely to get better over time.

Smarty Mobile’s 5G frequency allocation

Frequency

Network type

3.6-4GHz (3600-4000MHz)

5G

3.4GHz (3400MHz)

5G

2.1GHz (2100MHz)

3G

1.8GHz (1800MHz)

4G

1.4GHz (1400MHz)

4G

800MHz

4G

700MHz

5G

Smarty Mobile has access to the same 5G spectrum as Three, meaning that it should be able to access all the frequencies above.

For 5G that means 700MHz, 3.4GHz, and 3.6-4GHz. The bulk of that is high frequency, which is typical for 5G, as it’s available in greater capacity, making it ideal for handling lots of simultaneous connections and general high demand.

However, low frequency spectrum – like 700MHz – can travel further and pass through objects more easily, so it’s handy to have some to help bolster the network.

In total Three/Smarty Mobile has 160Mhz of 5G spectrum (including its 20MHz of 700MHz spectrum). For comparison, EE has 120Mhz, O2 has 100Mhz, and Vodafone has 90Mhz. So Smarty is in a strong position here.

However, all of the networks could potentially acquire more 5G spectrum at future 5G spectrum auctions.
