What’s the best mobile network for me?

Choosing a network

Looking to switch to a new mobile network? We outline some of the extras you can get from each of the UK’s major mobile providers.

Choosing a mobile network can be a daunting experience at the best of times.

Each offers its own set of unique perks and extras to attract you - from the generous data plans of Three to pre-sale tickets to events from O2 to courtesy phones from Vodafone if yours needs repairing.

While it's easy to compare prices, working out what extras each offers can be a dizzying experience. With that in mind, we've pulled out the selling points for each of the UK's major mobile networks to help you decide which appeals to you.

Smarty

Smarty logo

What can you get from Smarty?

You can get 30-day SIM-only deals. There are no handsets available from Smarty - it deals just in flexible SIM plans.

Right now, there are three to choose from, aptly named Small, Medium, and Large, so picking the best one for you is easy.

The main advantage of choosing Smarty is that if you don't use up all your data allowance in the month, the network will buy back what you didn't use - at a rate of £1.25 per GB. That's great if your mobile use is a bit erratic month-to-month.

What's Smarty coverage like?

Smarty uses Three's network to reach you. That means 99% of the population can get signal to call or send a text, around 97% can connect to 3G, and about 90% can use fast 4G.

Why choose Smarty?

  • 'Sell' any data you don't use
  • Simple, straightforward plans
  • Good coverage
  • Good value add-ons if you run out of allowance
  • 30-day SIMs that can be changed or cancelled at any time

Vodafone logo

What can you get from Vodafone?

What can't you get? Vodafone has one of the widest choices of phones of any major UK mobile network, including iPhones, high-end HTC and Samsung phones and mid-range classics like the Motorola Moto G.

It's far from the cheapest option, but if you're looking for lots of choice, you won't find much better. Vodafone also has a handful of reasonably-priced SIM-only deals.

What's Vodafone coverage like?

Vodafone's 3G coverage reaches 90% of the UK population. As you'd expect, Vodafone's 4G coverage is less extensive, especially compared to EE, but Vodafone is expanding it city by city, so if it's not available where you live, it may be in the coming months.

Its deals are built around basic value, flexibility, and simplicity, with a few little extras like capped plans and data rollover to let you save even more money.

What's iD Mobile coverage like?

Since iD Mobile uses Three's, coverage ain't half bad - 97% of the UK population can connect to its 3G alone. 4G coverage is far more limited; it's primarily found around large cities like London, but expanding rapidly.
