Hi HN,<p>We work on a website and we need to send daily sms to our website's contacts.<p>My question is:<p>Is this what we call as a SMS Gateway Service?<p>If Yes, can you give me examples and the best known Sms Gateway Services.<p>If No, what is the name of my solution and from where i can start?<p>Thank you.
If you need to send SMS I highly suggest integrating Twilio to your site. Another one I have used is Nexmo. Either one can be integrated really pretty easily and only takes a short while. Plivo is another one I have heard about, but I know nothing about them.<p>You do not yourself need to be a SMS Gateway, in fact it is a royal pain, just use a quality service and integrate it. It does have a small nominal cost per SMS message, which you can see on each website.<p>Twilio provides libraries to integrate for common languages like node, Ruby, Java etc.
Depending on the load requirement, I have used NowSMS (nowsms.com) for some of my projects. NowSMS is pretty straight forward to use. For others, I wrote my own gateway using Smslib - that can be a pain though, depending on the phone you want to you.
