HeidiTel provides low-cost international roaming in more than 190 countries. With HeidiTel, you get a new number and SIM card to put in your existing GSM (SIM card) handset to use while travelling.
HOW DOES IT WORK?
HeidiTel is a prepaid SIM card that uses callback technology to save you up to 90% when calling and using mobile data. All you have to do is dial a number from your phone as usual. HeidiTel does the rest of the work by picking up your call, connecting it to the number you dialed and calling you back (thereby connecting the two ends of the line). Incoming calls are free in 140 countries, HeidiTel users can call each other for only 0,19 eur/min and calls within the EU are also only 0,19 eur/min.
