We spend a lot of time here at T3 trying to find the best SIM Only deals for different needs and occasionally we come across one that works for everyone. This time it's from Three, which is offering unlimited everything – data, calls, texts – for just £18/month right now.

The benefits of having unlimited everything should be obvious: worrying about running out of data, minutes, or text will be a thing of the past. Plus, thanks to the SIM Only nature of the offer, you can put this SIM in any phone, tablet, laptop, WiFi hotspot, e-reader, and whatever else. 

Three explicitly says that using this SIM as a personal hotspot is allowed, meaning not only do you get unlimited data, but so does everything else in your family, on the train, and wherever else you happen to be. Okay, we're joking about on the train, but you could if you wanted.

The SIMs are also 5G ready, so when you upgrade your handset to the latest edition, you can make use of ultra-fast mobile connections across the UK. Roaming is also sorted across the EU, meaning you can use your data like you normally would.

The deal on offer from Three bests similar deals from other carriers, although they have their perks. EE, for example, is offering 80GB of data plus a load of different subscription trials for £20/month while Vodafone has a cashback plan that offers 60GB of data for under £10/month. But overall, Three has the best deal on offer.
