how to flash straight talk service to sprint phone

[CACQLD13]

I'm trying to figure out if there's any way I can flash/transfer my straight talk service plan that I have active now with my current phone ZTE Quartz model z797 to my new phone a Galaxy Core Prime which is from sprint but it isn't connected. I want to keep my service plan active from straight talk but just replace the ZTE with the Galaxy.

contact straight talk to activate a different phone.
