Does anyone know of issues with Alltel that it wouldn't even pass
through Alert messages at all?

GMS seems to work just fine for anyone on Verizon - but Alltel messages
never get to the phones at all - not even alert confirmation messages.
(but those do woek fine on Verizon).

I've tried with 3 different Alltel phones and they never get any kind
of text message for GMS at all.

Any ideas?
