What network does Smarty use?

Smarty is a virtual provider, which means it uses another provider's infrastructure – in this case, the Three network. It offers 3G, 4G and 5G coverage.

How good is Smarty's mobile coverage?

Smarty offers 3G, 4G and 5G coverage with Three's network, claiming coverage of more than 97% of the population. 

To check coverage where you live, use a mobile network coverage checker. Simply enter your postcode into the map and it will tell you how good Three's signal is in your area, as well as comparing it with the other providers.

Other Smarty deals and incentives

A social tariff is available for eligible customers, offering unlimited data for £12 a month. 

It also has three 'data discount' deals, where instead of rolling over unused data, it refunds the cost of the unused data at a price of 1p per MB. 

Smarty doesn't have out-of-bundle costs, as minutes and texts are unlimited, and you buy data as an add-on.

Does Smarty increase its prices each year?

As Smarty offers rolling 30 day Sim-only contracts, customers are not hit by costly mid-contract price increases. Before the end of the month, you will be able to check what the price to renew is. 

If it does increase or is too expensive, you can simply switch to a different network with no penalty.
