How the Xmas 3 months free offer works in a nutshell

Three Xmas offer

Pay no monthly charge for your first 3 months

This is Three's most generous offer in 2016 and it's a simple as it sounds. You'll pay nothing for particular SIM only plans or phone contracts for 3 months.

On a 12-month SIM only deal, this is the equivalent to 25% off your monthly charge and on a 24-month phone contract, it's like getting 12.5% off.

Of course if your phone comes with an upfront cost or if you run up any extra charges for usage outside your regular plan, you will still have to pay these during the 3 free months.

It's worth noting you will still pay for your first 3 months but the cost will be credited back to you in your 4 month with Three.
