[GS5 Lollipop]

Hey guys,
Currently, I have the GS5 running G900AZ(Cricket variant). Unfortunately, cricket has no released lollipop and likely will not. Can I install lollipop from a different provider? Basically putting in a SIM card from another carrier, entering my unlock code for my device, and updating and then going back to the cricket SIM? Please help haha. Thanks in advance!

No.

If you get fed up waiting for a carrier the alternative is to root and install a custom ROM. But not everyone is comfortable with that.
