You need GSM Modem and you can send SMS through that GSM modem.

Buy GSM modem, then communicate to that GSM modem using SerialPort (as far as I know). Send AT command to send SMS. http://www.codeproject.com/Articles/38705/Send-and-Read-SMS-through-a-GSM-Modem-using-AT-Com – Jun 28 '16 at 13:51
Is there any other way?and if no, which external site is more effective to use ? – sara adly Jun 28 '16 at 13:55
The choices are external sites or your own hardware. Just choose the easiest one... have fun... – Jun 28 '16 at 13:57
Ok, thanks for your precious time, but I ask is there any another external site is better than Twilio ? – sara adly Jun 28 '16 at 14:01
Sorry, never use service like that before... I use my own hardware gsm modem – Jun 28 '16 at 14:03
Well you excluded explicit **any** external sites/services in your question - so there is the only option to run your own gateway to the cellular network – Sir Rufo Jun 28 '16 at 14:18
@SirRufo So, If I use external Site is there any another external site is better than Twilio ? – sara adly Jun 28 '16 at 14:26
@Sara What do you mean by 'better than Twilio'? Are you talking about price? – Alex Baban Jun 28 '16 at 14:31
@AlexBaban More Flexible than it, because Twilio needs to verify all telephone numbers to send sms to it – sara adly Jun 28 '16 at 14:32
