I feel bad saying this but among all the data problems, I also have text problems.
Today I kept getting something like "text message memory full" even though I had NO messages. Something was trying to get through but could not.
I tried restarting etc, nothing helped.
About 4 hours later my phone blew up with messages pouring in.
This is not the first time I had this problem, nor is it the first time I have received messages hours or days later.
This also happened years ago when I had a regular Virgin mobile phone, so its not something new.
