You will also get some credit to try out.

*** Start saving in 3 simple steps ***

1. Before departure, launch Roamer and tap ‘Park My Number’.
By parking your number you link your regular phone number to a temporary dedicated number Roamer. It will be later forwarded to your foreign SIM card abroad.

2. Upon arrival in your destination, purchase a foreign SIM card and authorise it through Roamer.
You will need a SIM card with a minimal data plan to authorise your number.

3. Receive and make calls.
Once the SIM is authorised, calls to your regular number start reaching your new foreign SIM instantly. For international calls including your home country, use Roamer. To make local calls, use your phone's default dialer. Your SIM card balance will not be charged for using Roamer.

*** How Roamer works ***
Roamer uses a combination of technology and magic to let you avoid roaming while keeping your regular number. Roamer links your number to a foreign SIM card with no roaming charges. We use GSM to connect calls (not WiFi or 3G), thus offering excellent call quality regardless of the internet connection speed in the area.

*** How do I receive calls with my number?***
Once you authorise your foreign SIM card, calls to your regular number start coming in as usual. It's that simple. You don’t need WiFi or 3G for incoming calls.

*** How do I make calls with my regular number? ***
Roamer works via callback. To make a call, launch Roamer, select a contact from the list (or type the number on the Keypad) and press Call. Answer the incoming callback and wait for connection. The other party will see your usual caller ID.

*** How to make a local call while abroad? ***
To make local calls while abroad simply use your phone's default dialer. Local calls are provided by your foreign SIM operator and do not have direct connection with Roamer.

*** How do I get charged? ***
You will only be charged from your Roamer account when receiving calls incoming to your regular number and forwarded to your new foreign SIM or calling abroad with Roamer. Calls are charged on a per second basis with no connection or hidden fees of any kind. Rates vary depending on country. When calling locally and using the data connection you will only be charged from your foreign SIM card balance.

*** Which countries are supported by Roamer? ***
You can travel to 212 countries of the world while you originating the trip from one of the 54 countries where you can park your number. A detailed list of all supported countries is available on roamerapp.com or in the application.

*** Do you use WiFi/3G to connect calls? ***
No, we do not! We always use GSM to connect calls to ensure the best call quality possible. Incoming calls will reach your phone as usual, no 3G needed. To make an outgoing call you need a one-time Internet connection to send a callback request (WiFi, GPRS or higher quality connection). No voice traffic is broadcasted over the data connection, so it will take almost nothing of your data plan.

*** What about data roaming? ***
Once you arrive at your destination country, you install a new SIM card to use with Roamer. With a new SIM you normally get a data plan from a local operator, which is the cheapest option available. On top of that by running Roamer you keep your regular phone number for incoming and outgoing calls while saving up to 99% on regular roaming rates.
