Best eSIM for China Travel: Saily vs Nomad vs Airalo vs Holafly Compared (2026)

The ninety seconds that decide your trip

You land at Shanghai Pudong at 11pm. You need a map, a ride-hailing app, and a message to your hotel. Your phone shows no bars — roaming is off, and there’s no SIM tray to worry about anymore, because the plan you bought on your couch three weeks ago connects on its own. Or it doesn’t, because you bought nothing.

That gap at the arrivals curb is the whole game. China eSIMs are cheap (plans start at $4) and they install in minutes, but the purchase has to happen before you fly. Provider sites and apps are hard or impossible to reach from inside China, and Nomad states plainly that its China eSIM can’t be newly purchased from within the country. This guide compares five providers on their currently listed plan prices, then walks through installation, activation, and the one thing data-only eSIMs can’t do: receive an SMS.

What an eSIM actually does when you land

An eSIM is a software SIM. You buy a plan online, install a profile through a QR code or the provider’s app, and the phone treats it like any other cellular line — no plastic, no airport SIM kiosk.

In China, the mechanics matter more than the brand. A travel eSIM connects to a local network — Nomad travelers report landing on China Unicom, and reviews put Airalo on the same network — while the data itself routes through an international gateway such as Hong Kong. That routing is why multiple 2026 reviewers describe blocked apps (Google, WhatsApp, Instagram) working without a separate VPN app installed. Treat that as the common case, not a guarantee: CyberNews notes Airalo’s plan includes no built-in VPN, only standard cellular encryption, and experiences vary by app and by week. If access to specific services is non-negotiable, pack a backup VPN anyway.

Every plan below is data-only. No voice minutes, no SMS, no Chinese number. More on why that’s usually fine — and when it isn’t — further down.

Side-by-side: current plan prices

All figures come from provider pages and the comparison sources listed at the end of this article, verified July 2026. “Price per GB” is our calculation from the listed plan price, rounded; providers change plans often, so treat it as approximate.

Airalo — the safe default for short trips

Airalo’s China page starts at $4.00 for 1GB over 7 days. The mid-range tiers run $7 for 3GB, $10 for 5GB, $22 for 10GB, and $30 for 20GB, all with 30-day validity, per Cloudwards’ 2026 comparison — which also lists unlimited options at $11.50/3 days and $19/5 days. CyberNews pegs the cheapest plan at $4.50/1GB/7 days and flags the absence of any built-in VPN.

Two practical points. Airalo’s own guides confirm hotspot sharing works with its eSIMs, though MyChina Guide calls it device- and network-dependent — test your laptop tethering at home first. And Airalo is one of the few here with proper top-ups: rechargeable eSIMs can be refilled in the app without a new install, per Airalo’s support docs. If your trip might stretch, that’s a real convenience.

Nomad — the per-gigabyte price leader

Nomad’s China eSIM starts at US$4. The tiers that matter: MyChina Guide lists 5GB/30 days at $8, 10GB/30 days at $12, and 20GB/30 days at $22, and its authors calculate Nomad saves about $6 per 10GB versus Airalo for a China-only trip. eSIM4’s June 2026 roundup lands on similar numbers ($7/3GB, $12/10GB, $20/20GB).

Nomad’s hotspot policy is the clearest of the group: its blog states China plans include hotspot tethering with no data cap. Network reports point to China Unicom with 4G and some 5G. Two caveats: you must buy before arrival (new purchases from inside China aren’t supported), and if your trip extends past 30 days you’re buying a fresh plan rather than topping up. For multi-country itineraries, Nomad’s Asia-Pacific regional plans start around $0.39/GB.

Holafly — unlimited data, with two fine-print lines

Holafly sells only unlimited plans for China. Current pricing on its China page: $11.90/3 days, $20.50/5 days, $27.50/7 days, $36.50/10 days, $50.50/15 days, and $73.90/30 days. Per-day cost drops the longer you stay — from nearly $4/day to about $2.46/day.

Fine-print line one: hotspot sharing is capped. Holafly’s current pages say up to 1GB of hotspot data per day, and traveler groups have reported the China cap was lower (500MB/day) in the past. If you need to tether a laptop for video calls, 1GB/day evaporates fast. Fine-print line two: Holafly’s FAQ confirms traditional top-ups are no longer available — run out of days and you buy a whole new eSIM. The page also states the China SIM is data-only, with no local number for calls or texts. For heavy phone-based data use with zero counting, it’s still the simplest choice.

Saily — security features bundled in

Saily is made by the team behind NordVPN (Nord Security), per NordVPN’s own review of the product. China plans start at $4.49 for 1GB/7 days; eSIMdb’s listing has 3GB/30 days at $10.99, 5GB/30 days at $15.99, 10GB/30 days at $26.99, and about $44 for 20GB/30 days.

The differentiator is its virtual-location feature, a VPN-style routing option that users describe as producing fewer captchas and cleaner access to international services. Saily’s support site documents hotspot setup for its eSIMs. You pay a per-GB premium — roughly $2.70/GB at the 10GB tier versus Nomad’s $1.20 — for the bundled security tooling.

Jetpac — cheapest big data, plus a delay perk

Jetpac’s China plans start from $6, with data packs valid for 30 days once connected (unused packs stay valid for three months after purchase). Its own 2026 comparison lists 1GB/7 days at $4, 10GB/15 days at $14, and 20GB/30 days at $19 — the lowest per-GB price in this table at roughly $0.95/GB — and notes there is no unlimited tier for China. Jetpac supports 5G where available.

The odd-on perk is SmartDelay: register your flight in the app, and if it’s delayed, you and up to five companions get free airport lounge access, as described in Upgraded Points’ Jetpac review. Most travelers will never trigger it, but the data pricing stands on its own.

Data-only: when you still need a phone number

Here’s the catch nobody puts in the product title. A travel eSIM gives you data — nothing that can receive an SMS or a call.

For most short trips, that’s fine. WeChat and Alipay both accept foreign phone numbers at signup, and ChinaESIM’s guide concludes most travelers don’t need a Chinese number if they set their accounts up before leaving home. The setup sequence that traveler reports converge on:

1. Register and verify WeChat and Alipay (with TourCard or international card binding) at home, while SMS codes arrive normally on your home number.
2. Keep your home SIM active in the phone alongside the eSIM — a dual-SIM setup, with the eSIM as the data line and the home SIM for incoming SMS. Roaming SMS receipt is usually free; you’re not paying for roaming data.
3. Use the eSIM for everything data-hungry: maps, translation, payments, messaging.

The failure mode is the surprise re-verification. Mid-trip, Alipay or your bank may demand a fresh SMS code for a large payment or a security check. A data-only eSIM can’t receive it. With the home SIM still in the phone, the code lands anyway. Without it, you’re stuck in a hotel lobby borrowing Wi-Fi and hoping the app offers email verification.

Stays longer than a few weeks, or apps that keep rejecting your foreign number, change the math. eSIMs that include a +86 number exist (ChinaESIM sells one), and a physical prepaid SIM from a China Unicom or China Mobile store — passport required — remains the local-standard option.

Install and activate before you fly

How much data do you actually need?

Hotels, metros, cafes, and even many restaurants in China have usable Wi-Fi, so phone data carries less weight than on a European trip. A working guide: 5–7GB covers a week of maps, messaging, and occasional social media; 10–15GB covers daily Instagram plus some video; 20GB+ is for hotspotting a laptop, video calls home, and uploading photos nightly. Navigation and translation apps are light; video is what burns the allowance. When in doubt between tiers, the price gap between 10GB and 20GB at Nomad ($12 vs $22) or Jetpac (about $14 vs $19) is small enough to just buy the buffer.

FAQ

The right eSIM turns China’s connectivity situation from a pre-trip worry into a settings toggle you flip once at arrivals. Buy before you fly, keep the home SIM in for SMS codes, and the rest takes care of itself.
