Holafly Overview
Holafly is a Spanish eSIM provider known for one thing: unlimited data. No data caps, no throttling worries. But is it worth the premium over metered plans?
Japan Plans & Pricing
Holafly only offers unlimited plans, priced by duration:
| Duration | Price | Per Day |
|---|---|---|
| 5 days | ~$19 | $3.80/day |
| 7 days | ~$27 | $3.86/day |
| 10 days | ~$34 | $3.40/day |
| 15 days | ~$44 | $2.93/day |
| 20 days | ~$54 | $2.70/day |
| 30 days | ~$64 | $2.13/day |
| 60 days | ~$84 | $1.40/day |
| 90 days | ~$99 | $1.10/day |
Longer stays = much better value. The 90-day plan is $1.10/day โ excellent for digital nomads.
Network & Coverage
Holafly uses the SoftBank network in Japan.
- Good coverage in all major cities (Tokyo, Osaka, Kyoto, etc.)
- Adequate for most tourist routes
- Weaker than Docomo in rural areas and mountain regions
- Potential congestion in extremely crowded spots (Shibuya, Fushimi Inari)
The "Unlimited" Question
Holafly advertises unlimited data, but there are nuances:
- Fair use policy: After 90GB in some regions, speed may be reduced
- Japan specifically: Most users report no throttling for typical usage
- No hotspot/tethering: This is the biggest limitation โ you can't share data with other devices
- Data-only: No voice calls or SMS
Pros
- True unlimited data (no cap anxiety)
- Simple pricing โ one plan per duration
- Good app experience
- 24/7 customer support in multiple languages
- 365-day affiliate cookie (longest in industry)
