Low cost mobile network Smarty has unveiled an incredible sim-only deal for £18.
The unlimited data plan is running until 13th July, and best of all, there’s no contract, which means customers have total flexibility and control.
The bumper package is one of the cheapest on the market and also features unlimited calls and texts with no speed restrictions - perfect for those who want to stay connected with family and friends, or use their phone to stream and watch TV and films.
But, that's not the only great value option if you're considering switching to Smarty, which runs off Three Mobile's 3G and 4G network. Other big data plans include:

Rival network ID Mobile is also offering a similar unlimited deal for £20 on a 30-day rolling contract.
The network is also offering 50% off their unlimited data SIM making it just £9 per month for the first 3 months.
