Smarty mobile review 2020 - is Smarty any good?


A low-cost network powered by mobile giant Three, Smarty keeps things simple with its small selection of cheap SIM-only deals. Its flexible one-month contracts and discounts for unused data should appeal to anyone on a tight budget.

What’s good about Smarty?

  • Straightforward and affordable deals

Smarty plans

As a SIM-only mobile network, Smarty’s plans are all one-month contracts which focus on data and rewarding customers for any unused data each month.

You won’t be able to get a handset with Smarty and there aren’t many plans available, but the plans it does offer are very competitive and they all come with unlimited minutes and unlimited texts.

Data allowances range from 1GB to 8GB, so if you’re a heavy mobile data user you should look elsewhere.

Verdict: Good

Smarty is a good proposition if you’re on a tight budget or you don’t need a phone with your mobile contract. While there aren’t many plans to choose from, we like the rewards for unused data.

Smarty coverage

As it's owned by Three, Smarty uses the same network to deliver mobile services, which means its 4G coverage reaches 99% of the UK population.

Before you order it’s important to check you can get a signal in your home area using Smarty’s coverage checker - as well as areas you are likely to frequent, such as your place of work and route to work.

Verdict: Good

Three’s (and therefore Smarty’s) network coverage isn’t quite up with the likes of EE (who generally come out on top against all mobile networks), but it’s still very good.

Smarty pricing

One of Smarty’s strongest selling points is price - its SIM-only plans are very good value. All plans are 30-day contracts and include unlimited calls and unlimited texts.

If price is your biggest driver, Smarty rather cleverly will give you a discount on your bill if you have any leftover data at the end of each month.


Verdict: Good

If you’re on a tight budget and already own a phone, Smarty is a cheap and reliable network.

Smarty customer service

Unlike some SIM-only mobile networks, Smarty does have a dedicated customer support team which operates a help web chat at fixed times seven days a week. However, it’s difficult to pin down how effective this support is, as Smarty has not been included in any major customer surveys.

Smarty extras and benefits

  • Customers are rewarded for any unused data at the end of each month
  • Tether and hot-spot your data without speed restrictions
  • Use your Smarty plan as normal when travelling in the EU


Verdict: Average

The unused data discount is a nice touch, but Smarty doesn’t really offer much else in the way of extras.

Overall verdict

As it specialises in SIM-only deals, Smarty won’t be the right network for everyone. If you want a phone included with your plan, you should try a different supplier.

If you’re simply after a SIM deal, Smarty is well worth considering. Each plan includes unlimited calls and unlimited minutes - and even though there isn’t a huge selection of plans, there should be a data allowance to suit everyone bar the heaviest of data users.

Getting rewarded for unused data is a great idea - and as perks go it could be enough to tip the scales when comparing Smarty against other SIM-only providers.
