Messaging with Chomp SMS wifi in Airplane mode?

[mmiller2002]

I'm out of the US this week and want to be able to use sms message using the free wifi at the hotel. So, I set to Airplane mode to avoid any possible roaming charges and enabled wifi. But, my Chomp SMS does not seem to be working. Are there other settings? Thanks!

I believe you will need a cell signal to send SMS, but there are a couple apps out there where you can use wifi. Check halfway through this article to see the ones you can use:
