Moved overseas, upgraded Prepaid account to Unlimited International, "Phones not registered on a network, only emergency calls"

I just moved to New Zealand, I didnt think i would need my Prepaid Phone so i didnt bother to upgrade to an International plan before leaving the States. That is not the case, just about every account i need access to is requested a PIN be sent to my cell# (702 area number) to verify it is me. It has become more important then my Social Sec # at this point.... smh

I purchased the $35 Prepaid International Unlimited addon pack. However my phone still is not sending or receiving any calls/ texts.

When i do try to make a call it comes up at the bottom that " your phone's not registered on a network, so you can only make emergency calls".

It says i have 1 bar at the top, so i would imagine a call should be able to go even with low signal.

Airplane mode is not on.

I have gone into the general settings and had the Network Settings Reset.

I have taken the SIM out and turned phone off/on.

This is a Galaxy S22 running Android btw

Please Help!
