よくある質問
Why does this page's total differ from the rental invoice?+
Because the page only computes what you typed. If the invoice adds a damage waiver, delivery, an airport handling fee, or bills from the day the box was dispatched, the real figure will be higher. The fix is to correct the daily rate and the day count to match how that shop actually bills, then read the result again.
How many devices before pocket wifi is worth taking seriously?+
There is no fixed number, because the crossover depends on that shop's daily rate and on plan prices for that country, both of which vary widely. The direction is what generalises: the more devices online simultaneously and the tighter the group travels, the more the result leans to the rental. Enter your trip's real figures and find your own crossover.
Can hotspot sharing always replace a rental?+
Not always. Sharing has to be permitted by that particular plan, which its detail page states, and even when it is, you are limited by the host phone's battery and by everyone staying in range. If your group splits up often, sharing from one phone hits the same wall as carrying one rented box.
What if someone's phone does not support eSIM?+
Two workable routes: have a supported handset buy a hotspot-friendly plan and let the others connect through it, or use pocket wifi for that group specifically. Before deciding, check each phone with our device page or look for an EID line on the handset itself, since the same model sold in different regions can differ.
Which plan price should I enter if I have not chosen one?+
Size the data first, then take the price of a plan of that size for the country you are visiting. Entering the price of a plan that is too small tilts the comparison unfairly toward eSIM, because in practice you would end up buying more mid-trip.
よくある質問
At what group size does pocket wifi start to win?+
It depends on the prices you enter, but the break-even moves toward pocket wifi when the group stays together all day and several devices need to be online at once.
Can I just share a hotspot from an eSIM instead?+
Yes, when the plan states hotspot is allowed — every plan page here says so explicitly. The limits are the host phone's battery and everyone staying close by.
What if some phones in the group have no eSIM support?+
Have someone whose phone does support it buy a hotspot-friendly plan and let the rest connect through it, or use pocket wifi for that group.
