The address book (in my web-based program) has built-in functionality for sending out text messages to cellphones via a carrier's email app. IOW: I can send a text message via computer to a Verizon user's phone via their phone # - eg: firstname.lastname@example.org. With my server being in the U.S., this works great for all U.S. based carriers.
Unfortunately, carriers overseas do not let the text message go through from my U.S. based server. It appears that I would need to clone my program on a server in another country for the text messages to go through. Is there a work around that would allow them to go through to other countries from my U.S. based server.
To be clear, the text message originates from a computer, not from a cell phone.
Most carriers have an email to text gateway, the trouble us that they will only deliver messages to their own customers. If you know the carrier of the recipient the you use each carrier's email to SMS gateway.
Otherwise you have to find an aggregator, there are lots in the uk.
