Holafly and Airalo are the two most popular travel eSIMs for China. Both bypass the Great Firewall automatically through international roaming. Both work without installing a VPN app.
But they're very different in how they price, how fast they go, and how they handle "unlimited" data.
This guide compares them head-to-head with real 2026 prices, speed test data, and honest answers about throttling — so you can pick the right one for your trip.
30-Second Answer
| You Are… | Pick | Why |
|---|---|---|
| Tourist, 1–2 weeks | Holafly | Unlimited data, zero worry about running out |
| Light data user, 1 week | Airalo | Cheaper if you use under 5 GB |
| Remote worker / heavy user | Holafly | "Unlimited" (throttled after 1–2 GB/day) but won't cut you off |
| Budget traveler | Airalo | Lowest starting price ($4.50 for 1 GB) |
| Multiple countries in Asia | Airalo APAC plan | Covers multiple countries on one plan |
| Want absolutely zero setup | Holafly | One plan per country, instant activation |
The Big Difference: How They Handle Data
This is the single most important distinction:
| Holafly | Airalo | |
|---|---|---|
| Data model | Unlimited on every plan | Fixed data (1–20 GB) or unlimited add-on |
| What "unlimited" means | You never run out, but speeds throttle after ~1–2 GB/day during peak hours | Fixed plans: full speed until data runs out. Unlimited plans: similar throttle behavior |
| Throttle speed | Drops to ~256 Kbps–1 Mbps (enough for messaging, painful for video) | N/A on fixed plans (just stops) |
| Can you run out? | No — ever | Yes — on fixed plans, data stops and you must buy more |
What this means in practice: Holafly's "unlimited" lets you use Google Maps, WhatsApp, and browse the web all day without thinking about it. But streaming YouTube at 1080p will get throttled by afternoon. Airalo gives you full-speed data up to your cap — if you buy 10 GB, all 10 GB are at full speed.
Price Comparison: China Plans (2026)

| 30 days | 10 GB | $26.00 | $2.60/GB |
| 30 days | 20 GB | $42.00 | $2.10/GB |
Airalo Asia / APAC Plans (Multi-Country)
| Plan | Countries | Data | Price |
|---|---|---|---|
| 7 days | China + Japan + Korea + SE Asia | 3 GB | $13.00 |
| 15 days | Same | 5 gb | $22.00 |
| 30 days | Same | 10 GB | $37.00 |
If you're visiting multiple Asian countries, Airalo's APAC plan covers them all on one eSIM. Holafly requires a separate plan for each country.
Speed Comparison
Both eSIMs connect through Chinese cellular networks (China Mobile, China Unicom) and route data through international gateways to bypass the GFW. Speeds are similar because they use the same underlying infrastructure.
| Metric | Holafly | Airalo |
|---|---|---|
| Typical speed (urban) | 20–80 Mbps | 20–100 Mbps |
| Typical speed (rural) | 5–20 Mbps | 5–20 Mbps |
| 5G access | ✅ Yes (via China Mobile roaming) | ✅ Yes (via China Unicom roaming) |
| Latency | 50–100 ms (routed through HK/SG) | 50–100 ms |
| Streaming | ✅ 720p–1080p (before throttle) | ✅ 720p–1080p (within data cap) |
| Video calls (Zoom/FaceTime) | ✅ Works well | ✅ Works well |
Real-world note: Speeds vary significantly by city, time of day, and signal strength. Beijing and Shanghai get the best speeds. Mountain areas (Huangshan, Zhangjiajie) get slower but usable speeds. Trains (including high-speed rail) have decent coverage in eastern China but can drop in tunnels and western regions.
Great Firewall Bypass: How Each Does It
Both eSIMs bypass the Great Firewall through the same mechanism: international roaming. Your data is routed through international carrier gateways (Hong Kong, Singapore, or Japan) before reaching the open internet. The GFW generally doesn't censor roaming traffic to avoid disrupting international business.
| Service | Works on Holafly? | Works on Airalo? |
|---|---|---|
| Google Search | ✅ Yes | ✅ Yes |
| Gmail | ✅ Yes | ✅ Yes |
| YouTube | ✅ Yes | ✅ Yes |
| ✅ Yes | ✅ Yes | |
| WhatsApp (text + calls) | ✅ Yes | ✅ Yes |
| ✅ Yes | ✅ Yes | |
| Twitter / X | ✅ Yes | ✅ Yes |
| Netflix | ✅ Yes | ✅ Yes |
| ChatGPT | ✅ Yes | ✅ Yes |
| Google Maps | ✅ Yes | ✅ Yes |
| Google Drive | ✅ Yes | ✅ Yes |
Critical limitation for both: GFW bypass only works on mobile data. If you connect to hotel WiFi or cafe WiFi, you're back behind the firewall. Use mobile data only, or install a VPN for WiFi networks.

|---|---|---|
| Plan | 10 days unlimited | 10 days not available → use 15 days / 10 GB |
| Price | $36 | $21 |

| Winner | Holafly (at least you won't be cut off) |
Alipay/WeChat Conflict Warning
Both eSIMs have the same problem: When your mobile data routes through international gateways, Alipay and WeChat payments may fail because they need to connect to Chinese servers.
| Problem | Fix |
|---|---|
| Alipay payment fails on eSIM | Temporarily switch to local WiFi (or a China SIM if you have one) → complete payment → switch back |
| WeChat Pay fails | Same as above — switch to WiFi for payment |
| DiDi payment fails | Same fix |
Workaround: If your phone supports dual SIM, put a China Unicom SIM in the physical slot for Alipay/WeChat, and use the eSIM for everything else. This is the ideal setup.
FAQ
Does Holafly actually bypass the Great Firewall?
Yes. Holafly's China eSIM routes data through international roaming gateways (Hong Kong/Singapore). Google, WhatsApp, Instagram, YouTube all work without a VPN app. This only works on mobile data — not on WiFi.
Does Airalo bypass the Great Firewall?
Yes, same mechanism as Holafly. International roaming bypasses GFW censorship. Google, WhatsApp, all blocked services work on mobile data.
Is Holafly's "unlimited" really unlimited?
Technically yes — you never get cut off. But speeds throttle to ~256 Kbps–1 Mbps after approximately 1–2 GB of usage per day during peak hours. Enough for messaging and basic browsing, too slow for HD video.
Is Airalo cheaper than Holafly for China?
For light users (under 5 GB total), yes — significantly. Airalo starts at $4.50 vs Holafly's $19 minimum. For heavy users, Holafly's unlimited plan is better value because you never need to buy top-ups.
Can I use either eSIM for hotspot/tethering?
Holafly supports tethering on most plans. Airalo supports it on some plans but not all — check the plan details before purchasing.
What if my phone doesn't support eSIM?
Neither Holafly nor Airalo works on phones without eSIM support. Buy a physical Hong Kong SIM card (3HK, China Unicom HK) instead — same roaming bypass, but in physical SIM form.
Can I install these eSIMs after I arrive in China?
It's risky. The activation pages and app stores may be blocked. Install and activate before you fly to China.
Do these eSIMs give me a Chinese phone number?
No. Both are data-only — no phone number, no SMS, no voice calls. You keep your existing phone number for calls and SMS.
