My phone just started this issue where it will not show the caller id with anyone that is calling my phone. Doesnt matter if they are in my contacts or not just says no caller id. I have looked into my phones call settings for a caller ID thing and nothing. I have been on the phone with straight talk for a couple hours and all they have said is they need to call sprint. And they havnt called me back. I have factory reset it and formated it using the hard reset method. I am at wits end.
