Try using your cell phone carriers smtp instead if they have one.
Example if your carrier is T-Mobile you would use: myemail.t-mobile.com
and if it was AT&T you would use pdasmtp.attwireless.net
Note: If your carrier doesn't have a SMTP server do a web search for a free SMTP server., I know there are some out there.
