Im having this same issue. When I got my phone, it was fine. It would show up as the number calling even if I didn't have them saved in my contacts. Now, after the free trial of Verizon caller id that I never really even wanted, my phone only says unknown caller if I do not have them saved. This is the most ridiculous thing ever. Do I have to pay just to see a number? Because if that's the case I'll switch to a different company. How can I have it one day and then it be taken away after a free trial? That makes no sense... If anyone finds a solution to this please let me know.
