The small print
When periodically travelling in our Home From Home Destinations across Europe and beyond (HFH), calls and texts to standard UK landlines, UK mobile numbers, HFH landlines, HFH mobiles as well as data usage, will be charged as in the UK. Usage beyond a Fair Usage Policy may attract other charges. Full details, current list of HFH Destinations, charges, and terms are available at tescomobile.com/terms
