Unlocked LG G3 D850 losses 4G LTE Connectivity

I bought a LG G3 D850 and use cricket wireless as my wireless provider. It keeps losing the 4G LTE connectivity and goes down to Edge ( 2G I think ) and doesn't refresh or go back to 4G. It takes about an hour of two to lose the 4G signal. If I turn the airplane mode on / of or go to mobile networks and toggle the data on / of, the 4G LTE signal returns for a short time.

The cricket APN has set itself under access point names. I don't know what to do.
Also cricket doesn't send an sms message or push any kind of update.

Can someone give me any suggestions?

Thank you for your time.

Welcome to the G3 forum, and please forgive the tardy reply.

As a first step, have you asked your carrier to check that the SIM is good?
