Yep, it really does. Unlimited data means there’s no speed restrictions and no data caps when you use your SIM in a mobile phone in the UK. Just keep in mind that our fair use policy does apply – and when roaming in Europe, your data is capped at 14GB each month.
A SIM only deal gives you data, minutes and texts for a monthly cost. The difference, however, is that you don't get a new phone – you get the SIM, and just the SIM.
Of course. You can use our SIMs with any unlocked handset or, as we work with EE, any phone on the EE network too.
