SMARTY supports 3G and 4G technology.

SMARTY is powered by Three's strong and reliable 3G network. It covers 97% of the population, with fast speeds for browsing, gaming, downloading and emailing.

You’ll also be able to enjoy 4G with SMARTY, where available.

Please note that, unfortunately, we don't support 2G mobile phones on our network.

If you have a 2G device and your SIM does initially connect to the SMARTY network, this will only be temporary. Our systems will detect this pretty quickly and your device will soon stop working.

To check your coverage at any point, please use our coverage checker.
