Roamer enables you to use your number abroad without incurring roaming charges and make international calls from home or abroad at incredibly low rates.
Launching Roamer for the first time you register your regular mobile number. It will be used as your Caller ID on all of your calls.
Choose calls over either Internet (Wi-Fi/3G/4G) for extra savings or normal mobile networks for reliability. For latter you need an inserted, preferably local SIM card. You are dialing traditional phone numbers not usernames; the other party does not necessarily need to install Roamer, especially if she is your Granny or boss.
Information for nerds: Roamer will work regardless of what SIM you use in the SIM slot, be it voice or data SIM, whether currently in roaming or not, or with no SIM card at all.
*Incoming calls in Roamer while abroad are available for users with their main numbers in a limited number of countries. We are working on expanding the list and will announce when new countries are available.
