If you want to get your hands on new SIM deals this weekend only, there are three deals that stand out above the rest. These come from Three, Vodafone and Smarty, all market leaders at the moment. Most notable is Three and its unlimited data SIM plan. It'll only cost you €16 per month, but will reward you with completely unlimited data, minutes and texts - all with 5G at no extra cost! While Three offers the best overall value, a Vodafone plan with the same monthly cost may appeal to others. It costs €16 and gets you 60GB of data. Where this promotion has an edge over Tres is with the €30 cashback you'll get here, making your monthly bills just €14.33. Finally, if you're looking for something a little more flexible, Smarty is a great option right now. Choose your 1 month 30 GB mobile data plan and you will pay only €10 per month. It's a fantastic price and even if you don't get 5G, it lets you go whenever you want.
