Best Unlimited wireless hotspot plan in Western Europe

Can anyone recommend an unlimited wireless hotspot plan for Western Europe ( France, Italy germany, Spain etc)?

I currently have unlimited plans in the USA with both Verizon and AT&T

I need to connect my MAX Transit duo Pro router via SIM cards while we’re there.

Thanks so much

In Austria I can recommend DREI (3) Hutchison to you! No commitment needed for prepaid or postpaid! Details on
