Want use raspberry in a place where isn't any WiFi, but got GSM coverage.
Need connect to the device - e.g. looking for a sort of GSM modem solution what will works as classic old-style modem-based inbound connections, e.g.
- in my PC i will use GSM modem to call
- and the raspberry will listen for the ring and starts "ppp" or "slip".
So, the question is
- it is possible?
- what type of HW i should to use - e.g. exists some GSM modem what allows inbound conncetions?
- the SW solution is probably something like here:
In short: how to connect to the raspberry where isn't any Internet? (some good guide with some exact solutions would be the best :)
