Holafly — unlimited data specialist

Holafly focuses on unlimited data plans — no caps, no throttling (within fair-use limits). Ideal for heavy-data travelers who stream video or use their phone as a hotspot.

  • Pricing: from $19 for unlimited data, plans from 1 to 90 days
  • Activation: QR code delivery via email (no app required on iPhone)
  • Coverage: 190+ destinations with unlimited data on most
  • Support: 24/7 multilingual chat; refund available if plans don’t work
  • Our take: Best for travelers who don’t want to think about data limits. More expensive than Airalo for light users, but the best deal if you use 5+ GB/day.

How we pick providers

We only list providers we have personally verified. Every pricing table on a country page states the date the prices were checked. We don’t accept payment for placement — our picks come from the data, not from who pays us. Some links are affiliate links (we earn a small commission at no cost to you), and we disclose this on every page.
