if, like their one support tech, Fernando, you have no idea what an SMS gateway is, it’s a domain by which you can send texts via e-mail (and vice versa), and yes, Fernando, that is a thing; every wireless provider has it — [10digitphonenumber]@tmomail.com, [email protected], [email protected], etc. it’s how it works
*not* android specific, i know — sorry — but there are no results and CL’s own toll-free "support line," LOL! WTF?!
