Serious question -- I signed DW and myself for split time text messages at the ATT.COM link today. Her provider is AT&T, mine is MetroPCS. She's received the text message confirmation to reply back to confirm, but I haven't. Should I be worried?

What other options do I have?
I've set up to have Twitter posts sent to my acct of my results, but DW doesn't tweet
I don't want a repeat of a race (may have been last W&D) where only half of the text messages arrived, and then not until the next day
