Holafly’s “Unlimited” Data Has a Limit Nobody Mentions

Holafly charges $19.50 for five days of unlimited data, and that price is the same whether you’re going to Japan, the US, or Thailand. No destination-based pricing. No data caps on the screen. No worrying about running out of gigabytes while navigating a Tokyo subway station. That simplicity is why Holafly has nearly 99,000 Trustpilot reviews averaging 4.6 out of 5.

But “unlimited” has fine print. Fair-use throttling, a daily hotspot cap, and network partner variability mean the experience you get depends on how much data you actually use and where you use it. Here’s what the marketing doesn’t mention.

What Holafly costs (and why it’s the same everywhere)

Holafly uses flat pricing across all 200+ destinations as of June 2026. Five days of unlimited data costs $19.50. Ten days costs $36.90. Thirty days costs $74.90. A single day costs $3.90. These numbers don’t change based on whether you’re visiting an expensive data market like Japan or a cheap one like Thailand.

For frequent travelers, Holafly Plans offers two subscription tiers: the Unlimited Plan at $64.90/month and the Light Plan (25GB) at $49.90/month. Annual billing saves 22%. Both plans include “Always On,” a feature that gives you 1GB of backup data per month in 150+ countries even when your main plan isn’t active. That means you’re never completely offline between trips. Both subscription plans can be cancelled anytime with no penalties or fees.

Compared to Airalo’s capped plans, Holafly costs roughly 2-3x more for light data users. A 7-day trip with 5GB of usage costs $11-15 on Airalo versus $27.30 on Holafly. But for heavy users consuming 3GB+ per day, the math inverts. Two 10-day Airalo plans with enough data for heavy usage can cost more than one month of Holafly’s unlimited subscription.

The fair-use cap: where “unlimited” gets limited

Every Holafly unlimited plan is subject to fair-use throttling enforced by local carrier partners. When daily data consumption hits approximately 3-5GB (the threshold varies by destination), speeds drop to around 1 Mbps or less. For most tourists using maps, messaging, and social media, this threshold is never reached, but streaming, video calls, and laptop tethering will trigger the slowdown.

Holafly doesn’t publish these thresholds. You won’t find a page that says “Japan fair-use limit: 4GB/day.” The limits are set by each local carrier, and Holafly has no control over when or how aggressively they’re enforced. Travelers in the Philippines, Japan, and parts of Southeast Asia report hitting the wall most frequently, likely because carriers in those markets enforce fair-use policies more strictly.

For most tourists using maps, ride apps, messaging, social media, and occasional photo uploads, 3-5GB/day is more than enough. The throttle only matters if you’re streaming video, running video calls for remote work, or tethering a laptop. If that’s your use case, neither Holafly’s unlimited nor Airalo’s capped plans will fully satisfy you.

Hotspot: the daily ceiling depends on your plan type

Holafly markets hotspot/tethering as included, and it is, but the limits differ by plan type. Per-destination plans (the ones you buy for a specific country or region) cap hotspot sharing at roughly 1GB per day. That limit resets daily, but 1GB fills up fast when you’re tethering a laptop for email, Slack, and web browsing, let alone video calls.

The monthly Unlimited subscription ($64.90/month) includes unrestricted hotspot sharing across all destinations, a significant upgrade for remote workers and digital nomads. The Light subscription (25GB/month) shares its 25GB allocation across both phone and hotspot use.

For travelers who need to work from their phone’s connection on per-destination plans, the daily hotspot cap is the most significant limitation. Airalo’s capped plans allow hotspot without a separate sharing cap (you just consume data from your total allocation faster), making them a better fit for remote workers who can estimate their data needs. Local SIMs in most countries also allow unrestricted hotspot.

The workaround for per-destination plan users: use hotel or café WiFi for laptop work and save the eSIM hotspot for emergencies. But if reliable hotspot is your primary requirement, either upgrade to the monthly Unlimited subscription or look at alternatives.

29 buyer complaints from the scan data

The DecodeIQ voice profile surfaced 29 weaknesses across Reddit, TripAdvisor forums, editorial reviews, Amazon, YouTube, and Facebook groups. The most consistent patterns:

Fair-use throttling is the number one complaint. Travelers who chose Holafly specifically to avoid data anxiety are frustrated when speeds drop after heavy usage. The disconnect between the “unlimited” marketing and the throttled experience creates the strongest negative sentiment in the scan data.

Hotspot restrictions surprise buyers. The daily sharing cap on per-destination plans is not prominently disclosed before purchase. Travelers who planned to tether a laptop discover the limitation after arriving.

The app misreports status. The “My eSIMs” page sometimes shows incorrect activation status or remaining days. The app occasionally switches to Spanish without warning, which complicates troubleshooting for English-speaking users.

No carrier disclosure before purchase. Unlike Airalo, which lists the local carrier partner on each country page, Holafly doesn’t disclose which network you’ll connect to before purchasing. You find out after installation. This matters most in countries where carrier quality varies significantly, such as Indonesia, India, and parts of Eastern Europe, where being assigned to a secondary carrier can mean dramatically worse rural coverage.

China is a known problem. Holafly uses a virtual carrier, and Chinese apps and payment systems block virtual numbers. Travelers report being unable to use Alipay, WeChat Pay, or access certain services because the Holafly number is rejected. If China is on your itinerary, Holafly is not recommended. A local SIM or a China-specific eSIM is the safer choice. Separately, a 2025 study by Northeastern University researchers found that some Holafly eSIM traffic was routed through China Mobile’s network without user disclosure, even outside China. For travelers handling sensitive data or business communications, using a VPN alongside any travel eSIM is a practical precaution.

Refund disputes drag on. While Holafly advertises a money-back guarantee, forum reports describe promised refunds that took weeks to process or were never completed. The support team is responsive for initial contact, but escalation paths for refund disputes are less reliable.

Rural coverage varies. Like all eSIM providers, Holafly depends on local carrier partners. In rural New Zealand, one traveler had no signal while their companion on a different carrier’s local SIM had full coverage. The experience you get is only as good as the carrier Holafly contracts with in your destination.

Home SIM disruption after travel. A small number of travelers report that adding a Holafly eSIM caused their home SIM’s data connection to stop working after returning home, requiring a call to their home carrier to reactivate. Before departing, note your home carrier’s customer support number in case you need it.

What Holafly does well

Holafly holds a 4.6/5 Trustpilot rating with nearly 99,000 reviews, the highest in the travel eSIM category. The company offers 24/7 live chat with human agents, flat per-day pricing regardless of destination, and an “Always On” feature that provides 1GB of free backup data monthly in 150+ countries between trips. Since November 2025, unlimited plans include a US, UK, or Canadian phone number for receiving SMS verification codes.

The core value proposition is real: you buy once, forget about data, and use your phone normally for the duration of your trip. No mental arithmetic on gigabytes. No stress about running out while navigating an unfamiliar city. No mid-trip top-up purchases.

That said, when issues escalate beyond basic troubleshooting, some travelers report support cycling through the same steps without resolution, particularly for connectivity failures that depend on the local carrier partner. The initial response is fast. The depth of resolution varies.

The “Always On” feature is a unique safety net. Your Holafly eSIM stays ready between trips. Land somewhere unexpectedly or extend a layover, and you have enough data for basics without buying a new plan.

How to buy and what to watch out for

The purchase process: visit holafly.com or download the Holafly app, choose your destination, select how many days you need, pay, and receive a QR code by email. Scan the QR code on your phone to install the eSIM profile, then label the new line something like “Travel Data.” Before departure, enable data roaming on the Holafly eSIM line and disable data roaming on your home SIM.

That data roaming toggle is the single most important setup step. Enabling data roaming on the Holafly line sounds counterintuitive (roaming usually means expensive), but the Holafly eSIM requires it to connect to partner networks abroad. This is the #1 fix for “Holafly not working” issues, and it comes up in virtually every troubleshooting thread.

Three more things to watch out for. First, never delete the eSIM profile. Holafly’s QR codes are single-use, and there’s no easy recovery path for deleted profiles. Second, always install at home over WiFi before your trip, not at the airport. Third, save screenshots of your QR code and APN settings before departure. If you need to troubleshoot without WiFi at your destination, you’ll need them offline.

Who Holafly is right for

Holafly is best for travelers who use 2GB+ of data per day, hate monitoring usage, value strong customer support, and don’t need heavy hotspot access on per-destination plans. It’s the simplest eSIM experience on the market: one flat price, one plan, no decisions beyond trip length.

Holafly is not ideal for budget travelers on light data usage (Airalo is 40-60% cheaper), anyone who needs reliable hotspot for laptop work on per-destination plans (upgrade to the monthly Unlimited subscription or use Airalo’s unrestricted hotspot), travelers to China (virtual carrier issues), or security-conscious travelers who want a built-in VPN (consider Saily, which includes VPN and ad blocking from the NordVPN team).

Frequently asked questions

Is Holafly legit and safe to use?

Yes. Holafly was founded in 2018 and is headquartered in Dublin, Ireland. It has served over 15 million travelers and holds a 4.6/5 rating on Trustpilot with nearly 99,000 reviews, the highest in the travel eSIM category. The negative reviews that do exist focus on fair-use throttling, hotspot caps, and connectivity in specific destinations, not on legitimacy or security concerns.

Is Holafly really unlimited?

Holafly provides unlimited data on every plan, but speeds are subject to fair-use policies set by local carrier partners. In most destinations, you can expect full-speed data up to roughly 3-5GB per day. After that threshold, speeds may be reduced to around 1 Mbps. For typical tourist usage (maps, messaging, social media, ride apps), most travelers never hit this limit. Heavy users who stream video or tether laptops will notice.

Does Holafly work in China?

Holafly technically offers China coverage, but travelers report significant issues. Holafly uses a virtual carrier, and Chinese apps and payment systems (Alipay, WeChat Pay) block virtual numbers. Multiple travelers were unable to pay for anything or access essential apps on arrival. For China trips, a China-specific eSIM from a provider like China Unicom or a local SIM purchased at the airport is the safer option.

Can I share Holafly’s hotspot with a laptop?

It depends on your plan type. Per-destination plans cap hotspot sharing at approximately 1GB per day. The monthly Unlimited subscription ($64.90/month) includes unrestricted hotspot. For sustained laptop work, the subscription plan or Airalo’s capped plans (no separate hotspot limit) are better options than per-destination Holafly plans.

What should I do if my Holafly eSIM stops working?

Toggle airplane mode on and off. Verify data roaming is enabled on the Holafly eSIM line specifically (Settings > Cellular > Holafly line > Data Roaming ON). Check that the Holafly line is selected as your primary data line, not your home SIM. Restart your phone. If speeds are slow, check for carrier updates (Settings > General > About on iPhone, which can trigger a carrier settings refresh). Contact Holafly’s 24/7 chat as a last step. Keep your QR code and APN details screenshotted in case you need them offline.

How does Holafly compare to Airalo?

Holafly is simpler (unlimited data, flat pricing) with better support (4.6 vs 3.9 Trustpilot). Airalo is cheaper (40-60% less per GB for capped plans) with more destinations (200+ vs 200+) and no hotspot restriction on capped plans. Choose Holafly for heavy data use and simplicity. Choose Airalo for budget and light use. See the full comparison.

What’s the “Always On” feature?

Always On provides 1GB of backup data per month in 150+ countries at no extra cost, even when you don’t have an active Holafly plan. It automatically renews every 30 days. This means your Holafly eSIM is never completely offline, useful for unexpected layovers or spontaneous border crossings where you need basic connectivity.

Does Holafly include a phone number?

Unlimited plans purchased after November 2025 include a phone number for the US, UK, and Canada. The number supports inbound SMS and VOIP-based calling. Traditional incoming cellular calls are not supported. For other countries, Holafly plans remain data-only. Keep your home SIM active for calls and texts in those destinations.
