China eSIM Comparison 2026: We Checked the Prices, the Fine Print, and the Speed

Every "best eSIM for China" list reads the same way: a dozen providers, a handful of star ratings, and a lot of marketing phrases like "blazing fast" and "VPN-free access" with no actual numbers behind them. We decided to do something different — pull the real entry prices, read the actual plan terms, and compare them against a real speed test we ran ourselves.

The short version: Sigma Mobile's China eSIM starts at €1.44, well under every other major provider's cheapest plan, and in a live test in Shenzhen it hit 415 Mbps download with no VPN — a number no competitor publishes, because as far as we can find, none of them have run one.

What "Unlimited" Really Means on Most China eSIMs

This is the part most comparison articles skip. Nearly every competing "unlimited" China plan isn't actually unlimited at full speed — it's a daily high-speed allowance that quietly drops to a crawl once you use it:

• Airalo — unlimited plans give roughly 3GB/day at full speed, then throttle to around 1 Mbps for the rest of the day
• Saily (by NordVPN) — 5GB/day at full speed, then down to roughly 1 Mbps
• Nomad — 2–3GB/day at full speed, then down to around 1 Mbps, sometimes 512 kbps
• Jetpac — around 3GB/day at full speed, then roughly 1 Mbps
• Ubigi — a larger 20–60GB high-speed allowance depending on plan length, then down to about 2 Mbps
• Holafly — fair-use throttling applies, but the high-speed threshold isn't published at all, and hotspot use is separately capped at 500MB–1GB/day regardless of your plan

1 Mbps is enough to load a text-heavy page, slowly. It is not enough for a smooth video call, a large upload, or live streaming — exactly the moments a business traveler or a creator in China actually needs the connection to hold up. Sigma Mobile's standard China eSIM plans don't work this way: you get full network speed on the CMCC backbone for your entire data allowance, not a fast trickle followed by a throttle.

Entry Pricing: Sigma Mobile vs the Field

Prices below are each provider's cheapest published plan, converted to EUR for comparison, checked against their sites and recent independent roundups in October 2026.

Sigma Mobile's starting price undercuts the next-cheapest major competitor by well over 50%. To be fair to the competition: providers like Nomad do get more competitive on large bulk tiers, with per-GB pricing dropping to roughly $1/GB on their 50GB plan — so if you need a huge one-time data dump and price-per-GB at scale is your only concern, it's worth a look. But for the entry-level and short-trip plans most travelers actually buy, nobody we found comes close to Sigma Mobile's price.

Speed: One Real Test Beats a Hundred Marketing Claims

Here's what stood out most while researching this: not a single competitor in our research — not Airalo, Holafly, Saily, Nomad, Ubigi, or Jetpac — publishes an actual measured speed result for their China plans. Every "fast," "reliable," or "smooth 5G" claim in their marketing is just that: a claim, with nothing to back it up.

So we published ours. A Sigma Mobile customer ran a live Speedtest while standing in Shenzhen, Mainland China, on our China Mainland eSIM, with no VPN running: 415 Mbps download. That's not an average or a guaranteed figure — mobile speeds vary with location, time, and congestion everywhere in the world — but it's a real, unedited result, in a speed class none of the competitors above claim, let alone demonstrate.

The reason: Sigma Mobile's China eSIMs route data over international roaming through our direct partnership with China Mobile, rather than tunneling domestic traffic past the Great Firewall the way a bundled VPN has to. Less overhead, less to throttle, less to detect.

VPN-Free Access: Not Unique, But Worth Checking Closely

To be fair, Sigma Mobile isn't the only provider claiming VPN-free access in China — Airalo, Holafly, Saily, and Jetpac all make a similar claim through their own international routing or bundled VPN. The difference is in the detail and the backing:

• Several competitor sources we checked contradict themselves on whether their own China plans need a separate VPN (Airalo's and Ubigi's own marketing pages disagree with independent reviewers on this point)
• None of them publish a real speed test to go with the claim
• None of them run a dedicated local office in China — they're global marketplaces offering China as one of 190+ destinations, not a specialty
• None of the plans we researched offer a version specifically tuned for ChatGPT, Claude, and TikTok the way Sigma Mobile's AI & Streaming-Optimized eSIM does

Sigma Mobile runs its own office in Shenzhen, inside the Greater Bay Area, working directly with China Mobile International. That's the difference between a generic "Asia bundle" with China included and a provider whose entire reason to exist is making China connectivity actually work.

Three Sigma Mobile China eSIMs, Each Undercutting the Competition

• China Mainland eSIM — our core plan, from €1.44, on CMCC with the open routing behind our 415 Mbps test result. Get the China Mainland eSIM →
• AI & Streaming-Optimized eSIM — same fast backbone, from €1.45, with tuned routing for ChatGPT, Claude, and TikTok. Get the AI & Streaming Optimized eSIM →
• Greater Bay Area eSIM — from €1.56, covering Mainland China, Hong Kong, and Macau on one eSIM, where most competitors would require two separate plans. Get the Greater Bay Area eSIM →

(An honest note, same as always: network routing, app availability, and local policy can change, and no connectivity method — ours or anyone else's — can guarantee access to every service at every moment. We recommend testing the apps you rely on most as soon as you land.)

Frequently Asked Questions

Is Sigma Mobile really the cheapest China eSIM? Based on published entry pricing as of October 2026, yes — Sigma Mobile's €1.44 starting price is lower than every major competitor's cheapest plan, several of which start at $4 (around €3.70) or more. Large-bulk per-GB pricing from providers like Nomad can get competitive at scale, so if you need a single very large data allowance, it's worth comparing directly.

Is 415 Mbps guaranteed on every plan, everywhere, every time? No — that figure is a real, unedited result from one live test in Shenzhen, not an average or a guarantee. Mobile network speed varies with location, time of day, and congestion, as it does for every provider everywhere. What it shows is the ceiling our open-routing approach can reach, in a speed class no competitor we researched claims to match.

Why don't other eSIM providers publish real speed tests for China? We can't speak for them, but it's worth noticing: not one of the major providers we checked — Airalo, Holafly, Saily, Nomad, Ubigi, or Jetpac — has a published, verifiable speed result for their China plans. Their marketing language ("fast," "reliable," "smooth") isn't backed by a number you can check.

What does "unlimited" actually mean on a China eSIM? On most competing plans, it means a daily high-speed allowance (often 2–5GB) followed by a throttle down to roughly 1–2 Mbps for the rest of the day — too slow for video calls or streaming. Sigma Mobile's standard plans give you full network speed across your entire data allowance instead of a fast trickle.

Do I still need a VPN with Sigma Mobile? No. Our China eSIMs are built to provide open access without one, the same way several competitors claim to — the difference is we've published a real test to back it up, and we run a dedicated local office and network partnership in China rather than treating it as one destination among many.
