Question

I’m taking shots in the dark here. I’d like to create a web service where eventually I send an SMS by using my own hardware. I’m not sure what I need in order to send an SMS myself. I don’t want to use any of the existing SMS send services out there, I need to be able to send these SMS myself.

It looks like there’s one opensource project in particular that deals with this, “Kannel”:

what I don’t understand is, do I need to get a GSM modem to be able to send SMS? Do SMS gateways (like Kannel) eventually need to get to a GSM modem to send messages, or is there some other hardware you need to be able to actually send the messages?

Thanks

Answer 1

Just find an online SMS Gateway. These Gateway providers are your best bet since they have handled all the heavy lifting for you. Just utilize their API and you should be able to do whatever you want. Some of these gateways are free and some are not. I’ve included a short list below.

I’m sure there are a ton more, but this will get you started.
