Our verdict on each
Sakura Mobile
Sakura Mobile suits travelers whose whole trip sits in Japan, offering eSIM plans from ¥1,375 with unlimited data and a pocket WiFi option. It is a mvno on docomo, au and Softbank, but coverage is a single market and a fair use policy shapes what unlimited data means in practice.
Unidata

Pros and cons
Sakura Mobile
Pros
- Service runs on docomo, au and Softbank, the main domestic operators, so day-to-day connection comes from established networks
- The pocket WiFi is easy to get hold of: airport pickup, hotel or residence delivery and post office pickup nationwide, with a free return envelope
- eSIM plans from ¥1,375 pair unlimited data with hotspot sharing, and the pocket WiFi shares a connection across 15 devices
Cons
- Coverage is a single market: 1 country, so a multi-country itinerary needs another plan
- The fair use policy slows speed after a daily data threshold on capped plans and caps hotspot sharing by plan length, so unlimited data carries conditions
Unidata
Pros
- Daily rental at $5.99 keeps budgeting clear for groups sharing connectivity costs across companions
- Allowance of 3GB per day supports maps, messaging and streaming without hunting for cafe WiFi during outings
- Support for 10 connected devices lets family members stay online together from a shared hotspot
Cons
- Rental at $5.99 may feel steep across extended stays compared with Klook Japan SIM/eSIM at $1.05 for light phone use
- Allowance capped at 3GB per day means heavy streaming across 10 connections can use shared headroom quickly
- Fulfilment via Ships to address needs planning for delivery and return, unlike Cherry Roam pickup options for quick handovers
Who each suits
Sakura Mobile
Who it suits
- Travelers on a Japan-only itinerary who want unlimited data without tracking a daily allowance
- Groups and families who need one pocket WiFi shared by many devices, delivered to a hotel or residence
- Short city breaks and longer stays alike, since short trip and long trip plans cover both and top-ups can extend a stay
Who should look elsewhere
- Multi-country trips: Zwitchy covers 200 countries, far beyond a single market
- Buyers shopping the cheapest entry point: eSIMGo.is starts at $0.99
- Anyone heading to a different destination: SimToIsrael is priced from $25
Unidata
Who it suits
- Groups who prefer shared pocket WiFi over separate Cherry Roam units for phones and laptops together
- Families needing 10 connections with 3GB per day rather than Econet Telecom Lesotho options built for other regional travel
- Planners who value advance shipment via Ships to address over Klook Japan SIM/eSIM handling for quick solo activation
Who should look elsewhere
- Solo light users who would find Klook Japan SIM/eSIM at $1.05 simpler than carrying and charging a shared hotspot
- Travelers wanting instant counter pickup rather than Unidata fulfilment via Ships to address, where Cherry Roam handling may feel more direct

Questions about each
Sakura Mobile
What does Sakura Mobile cost for a Japan trip?+
eSIM plans start at ¥1,375, and the pocket WiFi runs at ¥299 a day with Unlimited data for the whole rental. The eSIM plans list unlimited data, 5g and hotspot, so a traveler can pick an instant activation eSIM instead of collecting a device.
Is the unlimited data really unlimited?+
Hotspot sharing is listed in the unlimited data, 5g and hotspot list, yet the fair use policy slows speed once a daily data threshold is passed on capped plans, and unlimited eSIM and SIM plans cap hotspot sharing by plan length. Heavy tethering is the part most likely to slow down or stop.
Unidata
How much does Unidata pocket WiFi cost?+
Daily rental is priced at $5.99. The charge covers shared hotspot use for the rental period, which helps groups split connectivity costs instead of buying separate plans for phones, tablets and laptops during sightseeing.
What data allowance is included?+
The Japan plan includes 3GB per day. That allowance covers maps, messaging, browsing and video calls during active travel days, though simultaneous streaming across many screens will draw down the shared pool faster than casual browsing alone.
