SMS gateway for incoming sms


It is necessary to implement interaction with GPS devices through the exchange of SMS messages. The mechanism for sending SMS is generally clear, but what about receiving SMS. are there any examples of similar solutions. I heard about the implementation via a GSM modem, but I’m unlikely to push it into the server room. maybe there are more elegant solutions.


I think that a two-party sms gateway is suitable here. The logic is as follows. You are sending a command to the GPS device. (for example, through the API from your system to the gateway server. Then the gateway sends an SMS to the device) If the device wants to answer, then it sends an SMS response to the same phone; The SMS response goes to the gateway server, notifies your server via the webhook (or you periodically poll for new SMS). and you are already responding to this SMS according to your business objectives.
