Description:

Jinggling makes simple, cheap and clear international calls right from your Android phone.

SIMPLE. Dial international numbers directly from Android dialer with “011” or “+” prefix. Or dial directly from contact book, history or favorite lists. No access number, no PIN, no password.
CHEAP. Most countries cost less than 3c/minute. No connection fee. No hidden charge.
CLEAR. We use the most premium routes. Hear it, believe it!
CALLER ID. Our premium routes carry your caller ID, a business class feature.
NO DATA. Jinggling does not use data to make calls. Instead it dials a domestic number to route international calls. More reliable connections and more consistent quality.

– Jinggling service is only available to US customers right now.
