Considering Galaxy S10

[DMLP411]

Pls bear with me for the noob question. I am a Tracfone customer and would like to purchase an S10. We are on Tracfone's Verizon network.

I have seen unlocked phones for both GSM & CDMA(which ours is). I'm trying to understand about SIM cards. One of the unlocked phones advertised states only for the Verizon network "must activate phone with an existing SIM card". Does this mean I remove the SIM card from my Galaxy J7 Sky Pro when I activate the new phone?

What would happen if I bought a new Tracfone SIM card? That wouldn't activate the phone?

Thanks very much.

If it's Verizon, think you'd better check with their BYOD site.

That should tell you what you can use, and about activations.

Somebody else who's actually in the US, may be able to give more details.
