Deal: Get 100GB for £10/mth

For a limited time, Smarty is dishing up 100GB of data, as well as unlimited texts and minutes, for £10/mth on a one-month, rolling plan. That's a whopping 60GB up from the usual 40GB and you can cancel the plan whenever you like.

Owned and operated by Hutchison 3G, the company behind the Three mobile network, Smarty has made quite a splash in the past few years. It came from nowhere to win our Best Mobile Network Award in 2022, then took the award for best 5G services and a Highly Commended overall last year. It isnt going away empty-handed this year, either, with the mobile network scoring a joint win with Voxi in the value category along with a Highly Commended for reliability.

Maybe its the low prices charged for its big data deals or its overall strong service and reliability, but Smarty is definitely doing something right with its customers. Nearly 60% (59%) told our survey they would be very likely to recommend it to a friend or family member, with a further 34% fairly likely. Around 5% said theyd be unlikely to recommend it; the second-lowest number for any featured network. Put that together with consistently strong performance elsewhere, and Smarty richly deserves another Highly Commended overall.

As a no-frills network, Smarty sticks to a straightforward lineup of SIM-only plans on 30-day rolling contracts. It offers a choice of voice plans for those who want calls and texts for their smartphones, or data plans for those who just want data for a 5G tablet or laptop. Voice plans start at just £6 for unlimited minutes, unlimited texts and 5GB of monthly data, then rise all the way to £20 for an unlimited data package. In between, youll find some great-value options, including a £12 deal with 120GB of data and a £15 plan with 150GB. Oddly, data-only plans can be more expensive. For instance, youll pay £17 for just 100GB.If you need more for a UK business trip or a week on holiday, you can buy unlimited data passes to cover you for a specific time period. One day will cost you £3, but you can have seven days for a tenner or 30 days for £17.

The Smarty customers we surveyed were enthusiastic about the value for money theyre getting with their plans. In fact, 100% told us they were satisfied. Whats more, 77% described themselves as very satisfied. As a result, the network was tied with Voxi for this years Value award, leaving most other networks in the dust.

Smarty lags a bit behind the market leaders when it comes to customer service. Of its users we surveyed, 36% told us they were very satisfied on this front, while a further 31% said they were fairly satisfied. To put that into perspective, Tesco Mobile scored 47% very satisfied and 40% satisfied, while Giffgaff scored 44% and 35% respectively. Smartys ‘very satisfied’ figures are down from last years survey, which were down from the year before; we hope they arent evidence of a long-term trend as the network grows.

Smarty runs on top of Threes host network, which the latest performance testing from RootMetrics ranks second in the UK for speed. Its UK median download speed of 44.5MBits/sec is far behind the 79.8Mbits/sec of the leader, EE. Smartys 5G test results are fantastic, with 5G median download speeds of over 100MB/sec in every area where RootMetrics tests, and speeds reaching 200Mbits/sec in nine of the 16 test cities and over 300Mbits/sec in two of those nine. 4G coverage is excellent, and 5G coverage is strong and growing fast. Thats great news for Smarty users.

Such consistently good speeds are also reflected in the networks performance and reliability scores: 41% of Smarty users told us that they always had a fast enough connection for general web browsing, while 52% said it was often fast enough. A total of 75% could always or often get the speed they needed to stream audio, and 65% said the same about video. Of all the networks covered in our survey, only Voxi achieved higher results. Hence another Highly Commended for Smarty, this time for reliability.

Smarty goes further than Voxi when it comes to roaming, offering free EU roaming across all its plans, subject to a 12GB limit. If you need to go above that, an EU data pass allows you to use the rest of your allowance, costing £3 for one day or £7 for three.

Outside the EU, charges are high enough to rack up some alarming bills, but not too expensive compared to other networks. In the US or Australia, youre looking at 50p per minute to make calls or 10p to receive them, 20p for texts and 10p per megabyte. In more expensive territories such as Kenya, for example, these rise to £2.50 per minute, 40p per text or £1 per megabyte.

Smarty is very much a no-frills network, so dont expect data rollover features, spending caps or any other freebies with the exception of Wi-Fi calling. This is where your phone uses your home or office network to connect if a mobile signal isnt available. Spending caps arent necessary anyway, as you cant use more than your paid-for allowance without buying extra credit. Its also worth mentioning that Smarty doesnt currently support eSIM technology, which will be a problem if you plan to use an iPhone 14 or 15, models that no longer have a physical SIM slot.

While the below-average customer service scores have stolen some of Smartys lustre, high scores elsewhere still make it one of the top no-frills networks and one of the best mobile networks overall. You dont get much in the way of features, but bargain data bundles, no commitments and free EU roaming go a long way. If youre looking for maximum data at the lowest possible price, Smarty is a great network to consider.
