I am currently working on a educational project and I need to send SMS to a mobile from my application. For the prototype, I don't actually need to use a mobile distributor.
I know it is possible to send messages to a mobile via a serial cable connected to the PC. Oher options would be to use a GSM modem or an operator gateway.
Does anyone have any recommendation on which would be the best option and also most economic?
I have been talking to different networks and mobile distributers to arrange some type of agreement but this is still ongoing...
