Question about Qynamic Q-SIM Zone Global

I don't understand your question exactly. The product is a SIM card that is compatible with both Android and iOS devices. A mobile hotspot also works.

Doesn't matter. I can highly recommend it if you want to surf abroad at low rates!
The (small) catch to the relatively low prices is that the initial credit expires after 3 months, while new top-ups expire after one month. So you should always buy the credit shortly before your trip and use it up as much as possible.

Thank you. It was a superfluous question. Sorry
