Network service stopped working on LG K51
I been having the LG K51 now for a few weeks and it was working perfect until yesterday. My service has went out, I cannot make or receive calls and texts, and have no data connection. It says I can only make emergency calls. My service came back one one time then went out again. I called tech support and they are sending another SIM card. I don't understand how it was working with no problem and no it's not.
