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 — 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 — you can't share data with other devices
  • Data-only: No voice calls or SMS

Pros

  • True unlimited data (no cap anxiety)
  • Simple pricing — one plan per duration
  • Good app experience
  • 24/7 customer support in multiple languages
  • 365-day affiliate cookie (longest in industry)

Cons

  • No hotspot/tethering — Deal-breaker for families or laptop users
  • SoftBank only — Weaker rural coverage than Docomo
  • Premium pricing — 7 days costs $27 vs $8-16 for 3-5GB metered plans
  • No voice/SMS — Data only
  • No top-up — Can't add more days, need to buy a new plan

Who Should Choose Holafly?

  • Heavy data users who stream video, make video calls, and post constantly
  • Long-stay travelers (30+ days) where per-day cost drops significantly
  • Anxiety-free travelers who don't want to think about data usage
  • Solo travelers (no hotspot means it's not ideal for sharing)

Who Should NOT Choose Holafly?

  • Families — No hotspot means each person needs their own plan
  • Rural travelers — SoftBank coverage is weaker outside cities
  • Budget travelers — 3GB for $8 covers most week-long trips
  • Laptop workers — No tethering for laptop connectivity

Holafly vs Airalo for Japan
