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?"](https://www.airalo.com/help/using-managing-esims/ZSEEHBT5HW6F/stay-connected-in-china-your-guide-to-unfiltered-internet-access-is-a-vpn-required/ZDZBNIKI4TFP) 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](/en/esim/) and [VPN guide](/en/vpn/).) ## 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](/en/esim/). ## Sources - [Airalo Help Center — Is a VPN required in China?](https://www.airalo.com/help/using-managing-esims/ZSEEHBT5HW6F/stay-connected-in-china-your-guide-to-unfiltered-internet-access-is-a-vpn-required/ZDZBNIKI4TFP) - [Airalo — China eSIM](https://www.airalo.com/china-esim) - [Holafly — China eSIM](https://esim.holafly.com/esim-china/) - [Nomad — China eSIM](https://www.nomadesim.com/china-eSIM) - [Saily — China eSIM](https://saily.com/esim-china/) - [Klook — China eSIM voucher](https://www.klook.com/en-US/activity/128576-china-esim-high-speed-internet-qr-code-voucher/)
