Who I have the same questioned this topic

I just changed from a $50/mo unlimited pre-pay (which expired a couple of days ago) to $35 500MIN/UNL TXT/500MB pre-pay. Then I applied a $35 pre-pay card on it. However, I never got the text from Verizon saying the funds were applied. My Verizon from computer shows the $35 transaction. The balance says $0.00. I can make and receive calls and receive text messages but I cannot send text messages. Is it not unlimited text as advertised? Did something go wrong with the transaction? Is it possible the $35 card went toward the $50 plan and is now lost?
