Send SMS text messages for free, without requiring any registration, nor entering any CAPTCHA code. There are some but minimal limits on the number of messages you can send. See textbelt.com for details on any limits. SMS support limited to carriers listed at textbelt.com.
Unfortunately, this service doesn't offer option to supply a reply number or address for recipient to reply to. But you can put that inside the SMS message if needed. For more details, visit http://www.textbelt.com
I built this app since the service provider offers just a developer API for sending free SMS text messages, now I'm providing an end user client for the rest of us!
For app support & source code, go to https://github.com/daluu/textbelt-clients/wiki/Getting-support-for-Textbelt-clients-from-this-site
Bear in mind some of your support issues may be specific to the textbelt.com API service provider rather than this app, so then I may not be able to help you in that case.
