Once you have read and agreed with our terms of service, registering with SMS outlined below:

First, an SMS must be sent to +420739367848
bearing a message in the form of Reg N

where N is the telephone number you wish to receive the one free airtime minute to.
Please note that the number must be in international format with a white space preceding the number.
For example, the SMS text to order one free minute to Moscow will be Reg 7495xxxxxxx

The SMS cost is the usual tariff of your mobile operator.

Having registered you will receive a free incoming call, accept it and wait for the connection to the number specified in the initial message you sent. After you are finished talking an SMS will be dispatched to you, containing your identification details for the FreeOpenCall network: your five digit unique number and authorisation password allowing access to the phone and statistics servers.

Please also note that if you have already registered this mobile number with our network, new registration will be denied.

All calls to your mobile from our network will be treated as incoming, meaning that your mobile operator will not be charging you for these.
