Nope. There’s no upfront cost for the SIM, and standard delivery is completely free of charge.
The cost of your airtime tariff will increase in line with the Retail Price Index (RPI) rate of inflation at the time with your July bill each year. This is the same for most networks in the UK and we’ll always give you 30 days’ notice of the exact increase so you don’t get any shocks in your bill.
Other than that, any extra charges on your bill would be for extra use outside your tariff. For example, if you use more UK minutes or data than your tariff gives you, if you use your phone abroad, call service numbers, premium SMS services, make calls to numbers abroad, directory enquiries, personal numbering or sending picture messages via MMS. So just keep an eye on that.
