How do i send a text message to a Mobile phone using gmail?
Go to your Gmail Labs settings and enable the "Text Messaging (SMS) in Chat" feature. The facility is currently available only for US phone numbers.


Send text messages from your Gmail chat window.


Enter the 10-digit area code and phone number in the chat window, and it will give the option to send an SMS. Click on it, enter your contact, type your message and hit Enter.


For a brand-new contact enter his number to begin the SMS process. Users can SMS their existing Gmail chat contacts by opening a chat window and selecting the option to send an SMS.


Once you enter their phone numbers, it will save the digits in your contact entries. This means that when those contacts go offline, the chat window will give you the option to switch to SMS.


When you send an SMS from Google chat, you get assigned a unique phone number for every pair of Gmail user and phone contact. That means that every time you SMS a contact, that contact will see the same number. That means the contact can add that to their contact lists on their phone.
