- Using GSM Modem
- Better when one wants to implement offline applications and very few number of SMS go every minute [usually few 10s]
- Using web service
- Better when it is online application and very few number of SMS go every minute [usually few 10s]
- Using endpoints given by service provider
- Better when number of SMS exceeds few 100s per minute. Service provider demands at least commitment of atleast 100,000 SMS per month.
Sending SMS via Webservice and endpoints are simplest. However sending SMS via GSM modem has few steps to take care of.
