Need An In-Car WiFi Setup

I need an in-car wifi setup, just curious if the Ltapmini is where I need to be looking with 2 sim cards/providers, is that really needed.
Main reason for this is my satnav provider has turned off my sim card, but It’s time to put a system in that I can move to new vehicles when selling.
Also will I need an APA-1. Or is this going over the top on either ?

APA-1 Recommended.

It you need an ltap mini an ltap or anything else (hap ax lite lte6?) depends on your requirements

Just a wifi feed for my satnav and some light browsing here and there, but reliable for the satnav traffic etc. All understood on the APA-1 thanks.
Is an external antenna required or will the internal ones on the Ltap-mini work well enough.

Hmmmm
