SMS Gateway for Windows + C# [closed]

by

Your options:

Email-to-SMS Gateway

Pros

  • Free

Cons

  • Delivery not as reliable as native
  • Non-standard message formatting between carriers
  • Subject to stricter ‘spam’ guards that can catch non-spam messages
  • You have to know what carrier your user is using, and they have to notify you if it changes

SMS Gateway

Pros

  • More reliable
  • Consistent formatting
  • Easily handle replies
  • Virtually indistinguishable to a carrier from text messages sent from a human
  • Most offer a simple API

Cons

  • Costs money. This won’t change until the carriers stop charging for them on both ends, which I wouldn’t hold your breath for since it’s such a huge profit center for them.

Do-it-yourself

Pros

  • You get to learn how GSM modems and AT commands work making you a 1337 hax0r.

Cons

  • Complicated
  • Still have to pay carriers per message
  • Doesn’t scale.

I happen to work for a gateway (Twilio) so I deal with this question a lot. We frequently have customers that started down the email route and gave up due to the hassles associated with that method. You can get away with email-to-SMS for small volume, non-important messages. If you’re serious about it, sign up for a gateway. There are a lot of them out there.
