I set up a second GV account using a Google number so I could use texting. I'm not a big fan/user, so even a $5 plan makes no sense to me, but I have one or two people who send the occasional text.
However, being under the impression that I could utilize the data part of my plan instead of incurring costs, I sent and received a few through the GV account. Afterwards, I checked my Verizon account and saw 27 texts (at 20 cents each!). WTF???
I called and explained the situation and was told that ALL GV texts as well as IM messages were chargeable at the text messaging rate.
Is this true for you or is there a way I need to set up GV so no costs are incurred?
