Free SMS API integration with my Web App [closed]

Question

I need to build a web application that sends a free SMS to its users. Now the problem is That I have no clue as to where do I get a free API to get this to work and how? Can someone help?

Answer 1

I believe most of the 'free' APIs make their money with ads embedded in your messages or sent along as a separate message. Additionally, the messages will likely come from a shared short code. If you're okay with those limitations, as @anirvan commented, google is your friend - here's just one example. Unlikely that you'll get wide international support (if that's something you need).

You could also try the email to SMS route, as many carriers will accept email to a unique address and forward that to the user. Again, google can help in finding those mappings. Note that the messages may not be in a desirable format, and if you do this with any volume, you may incur the wrath of the carriers.

There's also low cost APIs - certainly not free - but perhaps worth considering depending on your use case. Here are a few:

• Nexmo
• Twilio
• Tropo

If cost is your main concern, I think you'll find Nexmo has the most competitive prices.
