5G is very much here to stay in the UK, and the best 5G SIM deals include the usual perks associated with the technology: faster internet speeds, lower latency and improved reliability.

With the growth of 5G networks in the UK, it is becoming increasingly easier to find affordable 5G SIM only deals. In this article, I'll take a look at the best 5G SIM only deals currently available in the UK and the 5G coverage up and down the country.

#1 Three - Decent prices

Three is one of the largest mobile network providers in the UK now, even though it may seem like only yesterday that they were a newbie. Anyway, Three offer some of the best 5G SIM only deals around. They offer unlimited data plans with no speed restrictions, making it a great choice for those who use a lot of data. They also have good 5G coverage in major cities and towns, making it a great option for those who live in or travel to urban areas. Where things get a bit iffy though, are in the more rural spots.

By the way, Lycamobile's SIM Only plans use the Three 5G network, too. So if you're looking for decent roaming offers as well as reasonable 5G coverage - for example if you call overseas frequently - then Lycamobile are a good shout.

Lycamobile's offers a varied range of 5G SIM only deals, starting from £15 per month. Customers can choose from plans with unlimited data, giving them the freedom to use as much data as they need without worrying about additional charges.

In addition to their 5G coverage, Lycamobile also offers great value international roaming services, making it easy for customers to stay connected when traveling abroad. Their roaming services are available in over 40 countries, including popular destinations such as the USA, Australia, and Spain.

TIP: Three also offer mobile broadband. This is different as it requires a dongle; you can compare all Three broadband plans at broadband.deals.

#2 EE - Cheapest 5G offers

EE is one of the pioneers of 5G in the UK and has one of the largest 5G networks in the country. They offer a range of 5G SIM only plans, with prices starting from £20 per month for unlimited data. They also offer 5G coverage in over 70 cities and towns in the UK, making it a great choice for those who need 5G connectivity on the go.

#3 O2 - 5G available now

O2 is, of course, another major player in the UK mobile network market and has a growing 5G network. O2 offer 5G SIM only deals starting from £19 per month, with unlimited data and free access to O2's Wi-Fi hotspots. O2's 5G coverage is currently available in over 50 cities and towns in the UK.

Which networks don't offer 5G SIM deals?

All of the big (and small!) UK networks now offer 5G - except for Plusnet.

However, if you're a Plusnet customer and you do still want 5G, don't fret. You can always swap over to SIM Only, on either BT Mobile or EE (as they're all the same company).

In fact, EE do some of the best value 5G deals around, and are one of our top picks. With over 99% of the UK covered by either 4GEE or 5G, it's worth doing a quick price comparison on the latest EE SIM Only Deals yourself.

Are there any other networks with cheap 5G deals?

Generally, smaller networks will have cheaper prices. But this isn't always the case.

For example, Vodafone's range of 5G SIM only deals are worthy of considering, too. They offer unlimited data plans starting from £22 per month, which may sound expensive but you get great network coverage and lots of add-ons. Read our review of Vodafone's network & coverage here to find out more. Note that Vodafone's 5G network is available in over 60 cities and towns in the UK, and has slightly better coverage than O2.

Tesco Mobile is a MVNO or mobile virtual network operator that uses O2's network, and they offer some of the best value 5G SIM only deals in the UK. They offer unlimited data plans starting from £20 per month, with prices going up for those who want additional benefits such as free roaming. Tesco Mobile's 5G network is available in the same areas as O2's 5G network, so use the area checker above to find out if you can get these great SIM plans from Tesco.

As you can see, there are many great 5G SIM only deals available in the UK, with prices starting from as low as £15 per month. With 5G networks growing in the country, it is becoming increasingly easier to find affordable 5G SIM only deals that offer good coverage. Whether you live in a major city or travel frequently, there is a 5G SIM only deal that is perfect for you.
