Enter the number of devices that need to be online independently away from the hotel. A young child without a handset does not count; someone carrying a phone and a tablet who will use both during the day counts twice. What you are buying is connectivity for devices, not for people.

It depends on the handset and its operating system, which set different maximums, so there is no one number that applies to every phone. In practice the limit you hit first is not the device count but the host phone's battery and the hotspot's range. A single test at home before you travel tells you more than any specification.

Yes. Put several items in one cart and pay once; each plan carries its own separate profile and installs on a different handset. The thing to be careful about is that one profile belongs to one device, so write down which profile went on whose phone before departure day makes it confusing.

Put that phone on someone else's hotspot, or use a local physical SIM at the destination. Check before buying rather than after, because eSIM support depends on both the model and the market it was sold in — the same model bought in two countries is not always the same hardware.

No. It is arithmetic on the assumptions you typed, not a quotation. Real prices come from the plans themselves and vary by country, allowance and duration. Use this page to settle the structure — how many plans, for whom — then read actual prices on the plan pages.
