Need Help

[sirc saira]

Greetings
I have install kannel using sudo apt-get install kannel,able to 
stop/start/restart the services, and give a kannel user password. But I don't 
know to test it. 
  With the default configuration, when I type bearerbox or smsbox, panic error 
occurs?
     What brand of cellphone I must going to use? 
A little help is highly appreciated. Thnanks.
