When we send sms to others we have to pay for it. We have to recharge sms pack otherwise it cut our main balance. But when I visited this website I saved my money from then. It is easy to use. You would just go to the website https://site2sms.com and create a account there. Afterthat you can send voice sms, text sms etc without any cost just for free.you have not to recharge any extra sms pack for sending sms. Just you have to use your data to send sms. It very useful to them who send sms to many people a day. Thank you
