Has anyone used their Verizon phone on Celebrity? Do you hook up to the WiFi and just use it like you would onshore? Can I check my text messages thru wifi without getting extra fees? Tried calling Verizon, but got two different stories. Their website said can do pay as you go to make calls and texts. Customer service rep said have to go thru WiFi. Normally would not be a big deal, but my 97 year old Mom is still alive and in case an emergency happens and they need to reach me. Thank you in advance
