It may upset you, but you may be running into a Homeland Security issue and no one may tell you about it.
What you can try is to open the phone book and call each provider, but it seems like a security problem?
Need help about International Text Messaging. I live in NJ and I need to know which cell phone service provider I should choose which will allow me to send and receive text messages to Bangladesh. Presently I have Sprint PCS and they told me they do not have International Text Messaging capability. Your help in this matter will be highly appreciated.
