You can set a custom caller ID, and you see the per-minute rate before you dial, so there are no surprises on your bill. Calls go to both mobile phones and landlines. It works in desktop and mobile browsers, so you can call from a laptop at home or from your phone while you're out, using the same account and the same credit.

Who is it for? 002Call is handy for calling family and friends abroad, reaching banks, airlines and service lines in another country, or calling home while travelling without paying roaming fees. Many service numbers can't be reached from a foreign SIM, or cost a lot to call on roaming. With 002Call you just open the website, enter the number and press call.

Pricing: pay-as-you-go credits from $0.02 per minute, first call free, no subscription and no monthly fee. A simple, low-cost alternative to Skype, Google Voice, Rebtel, Viber Out and magicJack.
