Kyoto & Osaka 5 Days Couple: SIM/WiFi Guide

If you’re sticking together the whole trip, one shared pocket WiFi is the cheaper option for two people. If you’re likely to split up — one of you browsing Nishiki Market while the other checks out a temple — two individual eSIMs are worth the extra cost so neither of you loses connectivity.

Sharing vs. going independent

A shared pocket WiFi covers both of your phones from a single rental, so you’re paying once instead of twice. The catch is exactly that: it’s one connection, so whoever isn’t holding the router loses signal too. For a couple who plans each day together, that’s rarely an issue.

Two individual eSIMs cost more in total but mean neither of you depends on the other for internet access — useful if your days involve splitting up for a few hours here and there.

How much data does a couple actually use?

App / activity	Approx. data use
Google Maps navigation	~50-100MB per day of active use
Google Translate (camera mode)	~20-50MB per day
Social media browsing (per person)	~500MB-1GB per hour
Photo/video sharing between phones	~50-200MB per day

Shared on one pocket WiFi, a couple typically uses 2-4GB/day combined — well within any of the unlimited plans above. On individual eSIMs, budget roughly 1-2GB/day per person for typical use.

Recommended options

For a 5-day trip, the 4-day pocket WiFi rental undershoots slightly and the 7-day tier overshoots by two days — either works, and the per-day cost is close enough that it’s not worth agonizing over. On the eSIM side, Mobal prices its 5G Unlimited tourist eSIM by the exact day, so a 5-day plan covers exactly 5 days per person with no rounding up.

Kyoto and Osaka-specific tips

Kyoto’s hillier sightseeing spots — the Fushimi Inari trail, Arashiyama’s bamboo grove — can see brief dips in signal strength; it’s a geography quirk that affects every provider equally, so there’s no need to switch plans over it. If you’re tempted to lean on Kyoto’s free public WiFi instead, skip it for anything time-sensitive: it typically requires a fresh signup each session and isn’t reliable enough for navigation you actually depend on. Once you’re in Osaka, that concern disappears entirely — Dotonbori and Shinsaibashi’s dense urban coverage has no comparable weak spots.

Frequently Asked Questions

Is it cheaper to share one pocket WiFi as a couple?+

Yes, in total cost — one rental covers both phones instead of paying for two separate SIMs or eSIMs. The trade-off is that you both need to stay within range of whoever is carrying the router.

What if we want to split up during the day in Kyoto?+

If you expect to split up regularly, individual eSIMs are worth the extra cost so neither of you loses connectivity while apart.

Does a 5-day trip need a full week's rental?+

Not necessarily — a 4-day rental undershoots slightly and a 7-day rental gives you a buffer. Either works fine for a 5-day itinerary; the per-day cost difference is small.
