Airalo vs Holafly vs Nomad for China (2026): Which eSIM Actually Wins
All three get you past the Great Firewall with no VPN — so the real question is unlimited-but-throttled vs cheap-and-capped, and which one limits your hotspot without saying so. A head-to-head for China travelers.
Every “best China eSIM” list ranks the same brands and skips the comparison travelers actually search for: Airalo vs Holafly vs Nomad, head to head, for China specifically. Here’s the thing — they all clear the hard part (beating the Great Firewall) the same way. So the decision really turns on three boring details the marketing buries: how data is capped, what happens after the cap, and whether you can tether.
First, the part they all get right: no VPN needed
A China travel eSIM connects to a Chinese cell tower but tunnels your data out to a gateway in Hong Kong or Singapore before it reaches the open internet. Because the traffic legally exits China first, the firewall never filters it, and blocked apps work with nothing to configure. Airalo states this plainly for its own China eSIM:
“No. When using Airalo’s China eSIM, Regional Asia eSIM, and Global eSIM, a VPN is NOT required. Your traffic is routed through secure gateways outside mainland China.” — Airalo Help Center, “Is a VPN required?”
Holafly, Nomad, Saily and Klook’s China Unicom vouchers all work the same way in practice. So “does it bypass the firewall?” is a tie. The tiebreakers are below. (For the full mechanism — and why a local Chinese SIM does not do this — see our China eSIM guide and VPN guide.)
How we compare them
Three questions decide it for a China trip: (1) capped data or truly unlimited, (2) what the throttle does after you hit a daily cap, and (3) whether tethering/hotspot is allowed or quietly limited. Price matters, but it only means something once you know which of these you’re buying.
The head-to-head table
Prices and specs below are as of June 2026 — eSIM pricing changes often, so check each provider’s live China page before you buy.
| Data model | After the cap | Hotspot | Roams on | Indicative price | |
|---|---|---|---|---|---|
| Airalo | Capped, plus an Unlimited tier | ~3 GB/day, then fair-use throttle | Generally allowed | International roaming on a Chinese carrier (Unicom) | from ~$4; 1 GB / 7 days ~$5; Unlimited 3 days ~$11.50 |
| Holafly | Unlimited | Soft fair-use throttle (≤1 day) | Capped ~1 GB/day | China Mobile (international) | 3 days ~$11.70 · 7 days ~$27 · 30 days ~$74 |
| Nomad | Capped, plus an Unlimited tier | 512 kbps, resets every 24h | Full tethering | China Unicom / China Telecom | 1 GB / 7 days ~$4 · 3 GB / 30 days ~$9 · Unlimited 10 days ~$33 |
| Saily | Capped, plus an Unlimited tier | Not clearly published | Not clearly published | A major Chinese carrier (NordVPN-backed) | from ~$4.49 (1 GB / 7 days) |
| Klook | Resells China Unicom (metered + 5G unlimited) | Varies by plan | Varies by plan | China Unicom | Varies by promotion |
Airalo — the safe default
The biggest catalog (200+ destinations), the clearest first-party “no VPN” statement, and a familiar app. If you’re continuing past China to other countries on the same trip, Airalo’s regional/global plans are the reason to pick it. Entry price is around $4, with 1 GB for 7 days about $5 and an unlimited 3-day plan around $11.50 (as of June 2026). Carrier attribution varies by source, so treat it as international roaming on a Chinese carrier.
Holafly — true unlimited, with one asterisk
Holafly’s pitch is real unlimited data, and for a heavy on-phone user (maps, streaming, constant uploads) that removes all data anxiety. The asterisk most reviews omit: its hotspot is capped at roughly 1 GB/day, and the fair-use throttle can apply for up to a day to manage traffic. So it’s the best pick if everything happens on your phone — and a poor one if you planned to tether a laptop all day. One caveat on the “no VPN” claim: unlike Airalo, Holafly’s own China page doesn’t spell out the routing mechanism, so while independent testing supports that it works without a VPN, we don’t credit Holafly with a “built-in VPN” in its own words.
Nomad — the value pick that lets you tether
Nomad consistently comes out cheapest per GB (3 GB / 30 days for $9; 20 GB for ~$25 on sale), and unlike most rivals it actually prints the numbers: after your daily high-speed allowance it drops to 512 kbps and resets every 24 hours, and full hotspot/tethering is supported. If you want a working laptop hotspot but don’t want to pay Holafly’s unlimited premium, this is the pick. It routes via Hong Kong on China Unicom / China Telecom.
Saily — an eSIM with a real VPN baked in
Saily is NordVPN’s eSIM brand, so beyond roaming abroad it ships a “Virtual Location” feature and a DNS ad/tracker blocker inside the app. That’s genuinely useful if you’ll also use hotel Wi-Fi (which is firewalled and where an eSIM can’t help you). Pricing starts at around $4.49 for 1 GB / 7 days, and it offers an unlimited tier. Saily doesn’t clearly publish its China throttle and hotspot limits, so confirm those in-app if they matter to you.
Klook — the voucher option, not a separate network
Klook isn’t a carrier; it resells China Unicom international-data eSIMs (and a HK/Macau/mainland tri-region plan) as vouchers with QR delivery that activate in about five minutes. The appeal is a familiar marketplace checkout and local-carrier branding; the substance is the same Unicom routing. One real warning from Klook’s own listings: most phones bought in mainland China or Hong Kong can’t take an eSIM at all — relevant if you’re buying a handset there. Klook’s exact China Unicom prices vary by promotion and region.
So which should you actually buy?
- Short city trip, light user, lowest price: Nomad or Airalo capped plan.
- Heavy phone user who hates watching a data meter: Holafly unlimited — as long as you’re not tethering a laptop.
- Need a reliable laptop hotspot: Nomad (full tethering) over Holafly (1 GB/day cap).
- Continuing to other countries same trip: Airalo (biggest multi-country catalog).
- Also worried about hotel Wi-Fi / want a VPN too: Saily.
- Want a familiar checkout and don’t want to think: Klook voucher.
The mistake that makes people hate their China eSIM
The recurring reason travelers end up disappointed isn’t the brand — it’s the expectation. A China travel eSIM fixes which exit your traffic uses; it is not a full overseas residential connection and won’t let you freely switch IP “regions.” Travelers who only needed normal apps — WhatsApp, Gmail, Google Maps, YouTube, ChatGPT — are happy; the ones who expected it to behave like a home broadband VPN are the ones writing angry reviews. Buy it to make your everyday apps work, not to do everything a desktop VPN does.
The device trap (iPhone and Apple Watch)
Two hardware gotchas: travel eSIMs install on your iPhone or Android phone, not a standalone Apple Watch, and handsets bought inside mainland China or Hong Kong frequently don’t support eSIM at all. If you’re on a recent eSIM-only iPhone, installing before you fly is your only clean option — see the iPhone trap in our eSIM guide.
