Not reciving TXT messages from outside the O2 network

[Porcia]

I'm not receiving, or they are taking up to 30 min.TXT messages that come from outside the O2 network, like conformation TXTs even after having them resend when sometimes I'll get all or nothing. At first, I thought it was a phone problem, but I've tried in 2 different phones now, and it's the same on both.
