There are so many different types of phones on the market that it can be nearly impossible to provide a tutorial on how to send a text message from each and every one. This guide is intended to provide you with some basic and common information, but it is not intended to fit perfectly for every type of phone. Your best bet for learning how to use specific features of your phone is to consult the owners manual. If you do not have the owners manual for your phone, many phone manufacturers have their manuals available online. For example you can find manuals for BlackBerry users here. Check out the website for the manufacturer of your phone to see what they may have to offer. Also, you can probably receive service and tutorials from the store where you purchased the phone.
Much of the information contained in this tutorial is from an article found WikiHow.com.
