Text Message Problem with SMT5600

[Guest mmmaiki]

I have the SMT5600, unlocked, using on T-Mobile USA.

I have it set-up in T-Mobile, that a text message alert comes whenever I receive an E-mail, in the e-mail boxes I have set up on My-T-Mobile.

Previously this worked on the SMT5600, I received the text message with the title and first text, whenever an e-mail came into those boxes.

Recently, that stopped working. No text messages come in, although I do receive e-mails, including when I do a send-receive from the phone to get e-mails.

It could be a T-Mobile problem. I checked on the My-T-MObile site though, and it is still setup to send those alerts.

I suspect it might be a problem with the phone. If so, any way to check and fix that?
