My phone broke but i want to know who messaged me is there anyway i can view these messages online since i cant view them on my phone? If so how?
Unforetunately no.
You can view the number that the message came from and the date/time it was sent online through MyVerizon on your Usage details, or your Detailed Bill. It may take a while for that information to come though, and if you have no phone active on your line and delivery fails, i don't think it will show at all.
