I am new to iPhone, and this forum, so help on this issue would be appreciated. I prefer to buy my phone's unlocked. No bloatware, and if my carrier ticks me off, I don't have to buy a new phone. But, a voicemail notification shows up in text messages in some sort of code. Is there an app that I can download to help with this issue? If it makes a difference, I am on Verizon.
