I am a beginner in JavaScript. I would like to develop a JavaScript to send SMS to mobiles from my laptop or my mobile (java enabled though computer option would be better).
You could try these guys: http://www.zeepmobile.com/blog/?p=17
OR
Cellular carriers assign email addresses to their phone numbers and support SMS by email.
So if you can email, you can text.
format : (subscriber 10 digit number)@sms_providerdomain.xxx
Alltel @message.alltel.com AT&T @txt.att.net Nextel @messaging.nextel.com Sprint @messaging.sprintpcs.com SunCom @tms.suncom.com T-mobile @tmomail.net VoiceStream @voicestream.net Verizon @vtext.com (text only) @vzwpix.com (pictures and videos)
See the Phonegap SMS Plugin to send SMS messages and also see this.
