Three

Three

100GB Advanced Plan

  • MinutesUnlimited
  • TextsUnlimited
  • Data100GB
  • Contract length12 months
  • Monthly cost£26

Three is known for its cheap deals, and the 100GB plan seems almost too good to be true. Although Three offers an unlimited data plan as well, we figured that 100GB is pretty near the mark - and it's a few quid cheaper as well. Three's 4G network is smaller compared to the others, so it's worthchecking overage before you sign up. If you're in a 4G area, you can take full advantage of the 4G speeds; if you're not, you'll be automatically connected to 3G.

You can tether up to 30GB with this plan and roaming rates are reduced in many international destinations. The unlimited texts will keep you in contact with friends and family, and the unlimited minutes mean you can chat and relax.

Smarty

Smarty

8GB for £15

  • Minutes200 minutes
  • TextsUnlimited
  • Data4GB
  • Contract length12 months
  • Monthly cost£10

Smarty is the new 4G network from Three. It keeps things simple by offering just three plans. It also offers a refund if you don't use all your data, so if you are on the 4GB plan and you only use 2GB, you will receive a discount of £2.50 off the next month. (That's £1.25 per GB).

All Smarty plans come with unlilited texts and calls - you have a choice of 2GB, 4GB or 8GB plans - all of which come on a rolling 30-day contract. We've chosen to feature the 4GB deal here as the middle option. If it's too much, you get a refund, and if it's not enough you pay just £1.25 per extra GB of data.
