Solved! Choosing Tracfone sim kit

[GJT57]

I bought an unlocked Samsung Galaxy a50, and my idea was to move my existing tracfone plan from my old flip phone to the new phone by way of tracfone's sim kits. In the specs of the phone it says that it supports both GSM and CDMA networks, so my question is: does it matter whether I choose the verizon, t-mobile, or at&t sim kit?
Thanks in advance!

Contact Tracfone and see which one they say should be for the phone. If it supports both then chances are Verizon would work best, their towers tend to have the best service and coverage.
