Straight Talk service with an LG G3 AT&T phone

If the phone was originally an AT&T phone, then no you can't do that.

AT&T is a GSM network. So only GSM phones will work on that network. That means your phone is GSM. While Straight Talk has some phones that work on GSM and others that are CDMA (depends on the area you are in and if they are using AT&Ts or Sprints network) they are not convertible or interchangeable.

You would need to get a phone that comes from a CDMA network to get it to work for you.

MERGED QUESTION
Question from souring : "changing smartphones 4G network"

Is it possible to change my smartphones (LG-G3) network?from GSM to CDMA or vis-versa?

It has to have the radio transmitter and receivers for both networks to do that.
SOME phones can, plenty of phones can't.

True there are a few out there that do, but most don't. Especially in the US.
