How do I send a text while traveling in Japan.

[agnut]

I am traveling in Japan w/ my US purchased Thunderbolt. I
can send and receive calls fine.  I can receive
text but cannot send a text. I have removed and replaced my battery. Any ideas
how to make my text go through?

Are you sending with the correct Country Code preceeding the number for the person you are wanting to send to????
