Recommended microSim Card?

Hello, can you please recommend the best microSim card to use with the, Raspberry Pi Cellular IoT HAT – LTE-M & NB-IoT & eGPRS?
(worldwide version)

I traveled worldwide and found that there is no best sim card worldwide.
Any sim card that works almost worldwide are extremely expensive.
Best to buy traveler sim card locally where you are, and ask for APN before you pay for it.

Great, thanks Xelusi
