5G on SMARTY

In the UK, SMARTY has just added 5G coverage to all of their plans at no extra cost. This means you’re now able to access SMARTY’s 5G network if you’re using a compatible 5G-ready phone. There are three major benefits to this:

  • You’ll get much faster download speeds. On their 5G network, SMARTY offers an average download speed of more than 200Mbps. This is around 5-10 times faster than 4G. It means you’re able to stream, browse and download much faster on your phone. In some cases, download speeds can go up to 597Mbps.
  • You’ll get more network capacity. SMARTY’s 5G network has a lot more capacity for carrying mobile data. This means you’ll get a better experience in areas where lots of other people are also using the network at the same time (e.g. when using your phone in a football stadium, train station or shopping centre).
  • You’ll get lower amounts of latency. Compared to 4G, 5G networks have a lower amount of latency. This means you’ll get a more responsive experience – something that’s particularly important for things like online gaming on your phone.

SMARTY’s 5G network is powered by Three, who currently offer 5G coverage in more than 300 UK towns and cities. According to SMARTY, their 5G service is currently available on the following devices:

Alcatel: TCL 10 5G.

In recent years, SMARTY has been performing a major upgrade of their 4G network, alongside the launch of their new 5G service. On 4G, this has led to speed improvements of up to 130% in areas that have been upgraded with the latest technology. The 4G network upgrades consist of three major changes:

  1. The introduction of 4G+ technology. This combines multiple 4G frequencies to boost the speeds you can get on SMARTY’s network. This technique is also known as LTE-Advanced Carrier Aggregation.
  2. The upgrade of older 3G spectrum to 4G. This improves the utilisation of 2100MHz spectrum so you’re able to get faster 4G speeds rather than 3G speeds.
  3. The introduction of L-Band spectrum. Also known as Super 4G+, this involves the addition of L-band spectrum (band 32). It further improves the download speeds you can get on 4G.

SMARTY 5G Plans

You can get a 5G-ready plan from just £5/month on SMARTY.

At present, the most popular plans on SMARTY include 30GB data for £10 and unlimited data for £16. For lighter users requiring less data, there’s also a 12GB data for £7 which is also very popular.

The following table shows a list of SMARTY’s 5G-ready plans:

Download Speeds

In the UK, SMARTY uses Three’s network to power their underlying service. This is offered without any speed restrictions or caps. As a result, you should get the same download speed whether you’re using your phone on SMARTY or on Three.

According to Ookla (H2 2021 data), Three has the UK’s fastest 5G network with a median download speed of 259Mbps and a median upload speed of 14Mbps.

According to SMARTY, the estimated maximum speeds available on their network are as follows:

Technology Download Speed Upload Speed
5G Up to 597Mbps Up to 50Mbps
4G Up to 70Mbps Up to 22Mbps
3G Up to 18Mbpds Up to 2.6Mbps

In practice, the speeds you get will depend on your location and device. Factors such as the signal strength in your area and the amount of available capacity will also have an impact.

APN Internet Settings

To access the internet on your phone, it’s important to have the right APN internet settings set up for SMARTY’s network.

The following APN or Access Point Name settings will allow you to use data on SMARTY, both in the UK and abroad:

  • Hi Ken, Great news that my Smarty sim will now run 5g. However, Smarty have published a list of phones by brand and model as the only ones that will work on the smarty 5g network. Motorola is not on the list. Why would they do this?

    • Hi Dave,
      Great question! I believe the mobile networks often need to get their network/carrier setting updated by the manufacturer which might be one explanation for them not listing any 5G phones from Motorola. Saying that, if you have a 5G phone from Motorola, it’s always worth a try as it might be that they just haven’t listed it on their site.

    I just thought I would add my review. I was on a £1 for any package promotion, apart from unlimited, so went for 50GB (found promotion in a webpage advert). I stuck the SIM in a WIFI hotspot and put it in the window facing transmitter. I got quite good speeds in Speedtest.net but web browsing and you tube where a bit slow at peek time probably due to only being on 3G in Lanlithgow.

    As a result I would not recommend Smarty in my area but obviously, every area has different coverage, so give it a go and see what happens. I’m now with Lebara, which is more expensive but is 4G and a lot faster, and feels snappy when opening webpages, and video. Lebara is more expensive compared to Smarty so worth giving smart ago first incase it meets your needs.

  • Smarty do actually have a £5/month plan, they don’t advertise it much but it does appear in their Price Guide PDF. Only comes with 500mb data a month, but for low data users it may be the cheapest way to get unlimited calls and texts: https://smarty.co.uk/plans/500mb-data

    Also for anyone thinking about their unlimited data plan, have a quick Google around because they usually have an offer going for £15/month for your first year. However the T&C’s on that one say you have to arrive via an affiliate, so not sure they’ll let you actually sign up if you just roll up on their website!
