All our mobile tariffs come with unlimited calls* to standard, UK landlines and mobile phones that are in the UK, together with unlimited text messages* to standard UK mobile numbers that are in the UK and an agreed, fixed allocation of 4G data for use in the UK and our Euro Zone, per calendar month.

'Standard' is calls to 01, 02 03 numbers and the freephone numbers, 0800 and 0808. 'Standard' does not include calls to non-Geographic numbers (other 08 numbers, the likes of some banks or information services) and premium rate lines. MMS are not included as they are not standard text messages (SMS).
