I am using the Way2sms site for last 2yrs, I didnt found not even a single issue with Way2sms. They provide the service with Free of Cost, there is no limitation on the same. Moreover, the messages are delivered with in seconds, I can say that its even faster than our normal Mobile service provider.
Hence I request all of you, rather than sending message with Mobile Service provide with Sms charge, kindly use Way2Sms with no sms charge.
