 ====== Connect with a 3G modem with command line ====== ====== Connect with a 3G modem with command line ======
  
-I have a modem Huawei E1752Cu HSPA. What I want to do is the following: 1) send and receive an SMS using the modem and 2) establish a broadband connection using the modem. +This topic have been moved to [[raspberrypi:modem3g|here]]. 
  
-Because I don't have a concrete idea of what to do next, I am exploring both sides: 1) using sms to communicate with the raspberry and 2) using mobile broadband to communicate with the raspberry. The fares of having a mobile connected all the time (plain fare are about 15 euros/month) and in the case of the sms you only pay the sms you send, so in some cases is advisable using only sms.  +Please update your favourites.

-===== Setup modem ===== +

-Install modem-manager: +
- +
-<code> +
-# sudo apt-get install modemmanager +

-it will detect the modem, do necessary loading of modules and things like that. It is advisable to use it as a service, so when plugin the modem it will be authomatically configured.  +

-I reommend to run it the ''--debug'' option enabled in order to see what is happening behind the scenes:  +
