I'm using PHP to send out text messages using the format email@example.com and I'm using the mail() function. This has been working fine for most cellular carriers. But I've run into a snag on one carrier in Cleveland called Cleveland Unlimited (owned by Revol.com).
Their gateway is mms.revol.com so I send like this: firstname.lastname@example.org but the recipients don't receive the msgs.
Then I read about Gmail having the ability to email out an SMS Txt Msg. Enabling SMS Chat in the Gmail Labs section, I input one of the Cleveland Unlimited cell phone numbers and it gets thru!
So I'm a bit puzzled now. Is Gmail using another service to pass off the cell phone number and connect when using PHP's mail() function it won't connect?
I'm wondering if there is another way to send mail using PHP and not the default mail() function? Or am I just barking up the wrong tree? (wrong solution)?
Thanks for any thoughts on this problem.
