Our verdict on each
O!
O! is a Kyrgyzstan mobile operator whose support navigation includes an eSIM activation route and the My O! app. The plan catalogue lists one-week and four-week smartphone options; the navigation label alone does not establish who is eligible or whether activation is free.
povo2.0
povo2.0 is a prepaid eSIM for travellers who want unlimited data on a local home network in Japan rather than a roaming add-on, under a fair use policy. It suits both short stays and long stays, with top-ups from ¥600 and a budget model.

Questions about each
povo2.0
What does a povo2.0 top-up cost?+
Top-ups start at ¥600, and the plan list is a prepaid menu rather than a subscription: unlimited options for a few hours, a day or a weekend sit next to data-capped packs, with larger bundles for long stays. Overseas packs are priced per destination.
Is the data really unlimited?+
Unlimited data is offered, and unlimited data, 5g and hotspot lists it with instant activation and hotspot sharing. Fair use still applies: speeds can be cut when the network is congested, video or cloud gaming are the usual trigger, and sustained heavy use can bring a speed limit at busy times.
Which countries does povo2.0 cover?+
The service is built around its home market: country coverage is 1, and KDDI au is the network behind it, with the region listed as local. Overseas top-ups cover a set of destinations including the USA, Korea, Taiwan and parts of Europe and Asia, bought separately rather than as a single roaming plan.
How long does the data last?+
Validity follows the top-up you choose. The plan list runs from unlimited data for a few hours or a day, through a weekend bundle and month-long data allowances, to a year-long bundle priced monthly, so both short trips and long stays fit, which is why its audience covers short trip and long trip.
