BETA test.
The VoipBuster mobile client software is in BETA test. We've noticed that the software doesn't work for every mobile phone.
If the software doesn't work please try one of the other options on this page.

How does it work?

on your MOBILE phone go to http://gsm.voipbuster.com (on some mobiles you need to choose 'download application' on some phones you can just go to the webpage)
download and install the application, start the application
in "settings" fill in your VoipBuster username / password and your OWN mobile phone number (it's the A-side of the call)
go to the dialing part, select a phonenumber from your phonebook and press call.
Your phone will ring first. After you pick it up, we will dial the other number. Wait for reply and start talking.

The VoipBuster rates for calling to your mobile number and the number you wish to call apply (plus a callsetup fee of 5ct). Costs for the calls will be settled via your VoipBuster account, so make sure you have enough credit.

Example: You are in the USA and wish to call a landline in the UK. You pay a callsetup of 5ct plus a rate of 18Ct/Min + 1Ct/Min = 19Ct/Min
