Telestial are pleased to announce that it is now possible to add a 1 US number to your International SIM card! All International SIMs come with a 44 British Isles phone number, but now there is the extra option to add a 1 US number to your SIM for just $2 per month. This gives friends and family in the US the ability to call your international SIM card at the cost of a local call. To add a US number to your SIM card, simply select the option after you have purchased and activated your SIM.
