Getting connected in China: eSIM, or the SIM you already have
Last reviewed 22 October 2026
Almost every "China eSIM" comparison we found prices exactly one thing: a travel eSIM. There is a third option that no comparison we found prices — simply using the SIM already in your phone, on your own operator's published China roaming rate. Both can be right. This page puts the operator's actual numbers next to the eSIM shelf price, so you can compare them yourself.
Search snapshot: Google, United States, English, 22 October 2026 For context, the pages Google showed for "china esim" that day were, in order: nomadesim.com, Reddit, trip.com, airalo.com, esim.holafly.com, mobimatter.com, traveltomtom.net, billionconnect.net and saily.com. Every commercial result is a vendor selling its own product. The one independent site on the list, traveltomtom.net, sat at position seven — which is the strongest evidence available that a neutral comparison can compete here at all.
Option one: roam on the SIM you already have
This is the option that never appears in a comparison table, so here is what it actually costs, straight from China Mobile's published international roaming page, read on 22 October 2026.
Turning it on
Source: China Mobile, "International / China, Hong Kong, Macao and Taiwan roaming function" (国际/中国港澳台漫游功能), read in full 22 October 2026 — 10086.cn
Send the text GMKT to 10086, or use the roaming page on 10086.cn. The published advice for people who discover after landing that roaming was never switched on is to borrow a friend's phone and call the roaming hotline on +8613800100186. Once opened, it does not normally need closing again.
Source: China Mobile provincial company notices — Anhui, effective 29 March 2026: 10086.cn; Hainan, effective 1 April 2026: 10086.cn; Hebei, effective 20 April 2026: 10086.cn
As of 2026 this became a non-issue for many travellers: China Mobile's provincial companies have been enabling the roaming function free of charge as a service upgrade, with announcements in late March and April 2026 — for example a notice effective 29 March 2026 from the Anhui company, one effective 31 March 2026 from another, one effective 1 April 2026 from Hainan, and one announced 17 April 2026 effective 20 April 2026 from Hebei. Opening it is free. Using it is not.
What it costs
Source: China Mobile, published international roaming rates — 10086.cn
| Type | Published rate | How many places |
|---|---|---|
| Data, uncapped tier | 3 yuan per 3 MB, 30 yuan per day cap | 216 countries and territories |
| Data, middle tier | 6 yuan per 3 MB, 60 yuan per day cap | 32 countries and territories |
| Data, top tier | 9 yuan per 3 MB, 90 yuan per day cap | 5 countries and territories |
| Data, volume-limited tier | 30 / 60 / 90 yuan, 50 MB per day cap | 9 countries and territories |
| Voice | 0.99 / 1.99 / 2.99 yuan per minute | 247 / 12 / 7 countries and territories |
| Text | 0.39 to 2.89 yuan to send; receiving is free | 266 countries and territories |
Which tier you land in depends on the country you are roaming from, and the operator publishes the country table alongside the tiers. We have not reproduced it here: the formatting on the published page interleaves the voice, text and data columns in a way that is easy to misread, and a misread rate table is worse than no rate table. Read the country table on 10086.cn directly.
Read the two clauses under the data table before you decide. For the 216 countries and territories in the uncapped tier, data is throttled rather than cut off — you keep using it, at reduced speed, with no need to order anything. For the capped tier, you keep getting 20 MB free after the daily cap, and then data suspends at 50 MB for the day and resumes automatically at midnight Beijing time. Your clock is not your clock.
The throttled speed, exactly
The published limit after you pass the daily threshold is a maximum download rate of 384 kbps, restored at midnight the next day, Beijing time. 384 kbps is enough for maps and messages and not much else. On the capped tier the day ends at 50 MB — that is roughly one video call, or a couple of hours of maps, or a large number of photographs uploaded.
Day passes, which is what makes roaming competitive
Source: China Mobile, published day and monthly packs — 10086.cn
The headline per-3MB rate is not the price you pay if you order a pack. China Mobile's published options are:
- "Belt and Road" multi-country data pack — 130+ destinations, from 11.9 yuan a day, billed per day, speed throttled after a daily threshold.
- China / Hong Kong / Macau / Taiwan three-region pack — 1 to 30 days selectable, from 11.9 yuan a day.
- Greater Bay Area Hong Kong and Macau pack — 3 GB of high-speed roaming data, 11.99 yuan a day.
- International roaming monthly pack — from 10 yuan a month.
Two conditions on those packs are worth knowing, because they are the kind of thing that quietly void a purchase. A pack is valid for 90 days from the day you order it, and it lapses automatically if you never generate data traffic in the region it covers. It only takes effect on the first day you actually use data in that region, and the operator's own text says the effective time is whatever the confirmation SMS tells you on arrival — not the date you bought it.
So: order the pack before you fly, activate it on arrival, and expect a confirmation SMS that tells you the real start time. Buy it in the airport and the 90-day window starts running while you are standing at the baggage belt.
Option two: a travel eSIM
What Google showed on 22 October 2026, in order, with the entry price each vendor put in its own page title:
| Position | Site | Entry price in the page title | What the title says it is |
|---|---|---|---|
| 1 | nomadesim.com | from US$5 | Best Travel eSIM |
| 2 | — | Discussion thread | |
| 3 | trip.com | — | High-Speed 5G VPN eSIM guide |
| 4 | airalo.com | from $4.00 USD | World's first eSIM store |
| 5 | esim.holafly.com | — | eSIM with Unlimited Data Plans |
| 6 | mobimatter.com | from $3.99 | Choose Your Network |
| 7 | traveltomtom.net | — | Best eSIMs for China in 2026, after visiting China twice |
| 8 | billionconnect.net | — | Mainland China 5G eSIM, High-Speed Travel Data Plan |
| 9 | saily.com | from US$4.49 | China eSIM data plans |
Snapshot of Google's United States results for "china esim", 22 October 2026 These are the vendors' own advertised entry prices, read out of their own page titles on the day. They are marketing figures. Every one of them is a "from" price, which is the price of the smallest package the vendor sells — not the package most people need, and not the price for the data a two-week trip in China will actually consume. We publish them as a dated snapshot, not as a price list, and we did not verify any of them by checkout.
Two things in that list are worth reading carefully. First, the three pages that advertise 5G also advertise VPN in their own titles. Whatever the reason a vendor puts a feature in its page title, it is what the market has decided matters for a China connectivity product, and it is something a comparison page should be telling you about. Second, the one independent article on the list is a travel blog that says it visited China twice — which is a reasonable place for the real answer to live, and a reasonable place for us to point you.
How to compare the three options
| Home SIM on roaming | Travel eSIM | Chinese local SIM | |
|---|---|---|---|
| Your number | Stays your number | New number, or your number on a data-only profile | New Chinese number |
| Setup before arrival | Send GMKT to 10086, or order a day pack | Buy and install before you fly | None |
| Cost shape | Per-day packs from 11.9 yuan, or per-3MB with a daily cap | One package price, varies by data volume and days | Local prepaid rates |
| What happens when you go over | Speed drops to 384 kbps, or data suspends at 50 MB until midnight Beijing time | Depends on the package | Depends on the package |
| Usable for calls and SMS | Yes, at published per-minute rates | Usually data only | Yes |
| Biggest risk | You forget to switch roaming on, or you hit the cap on day two | You buy the wrong volume, or a package that does not cover China | Getting one at all — see below |
Do not compare the two prices directly without converting currencies. We do not publish an exchange rate, because it moves and a stale rate is worse than none. Both sides of the comparison are on the table: a day pack starts at 11.9 yuan, advertised eSIM entry points start at $3.99. The question that decides it is days and megabytes, not currency.
Option three: a Chinese local SIM
A prepaid Chinese number is the option that unlocks the most — domestic delivery, local apps, phone numbers that Chinese services expect — and the option that has the most friction for a short-term visitor, because getting one is a registration process with the operator, not a purchase.
Here we are on thinner ground than the rest of this page, and we would rather say so than fill the gap: we did not manage to read the operators' current published rules on issuing a mainland mobile number to a holder of a foreign passport — not the in-store identity check, not whether a local bank card or a local address is required, not whether it can be done online, and not whether an overseas-issued eSIM can be activated on a mainland network under those rules. Foreign guides state these requirements confidently and differently from one another, which is a sign that they are being written from memory rather than from a source.
Source: China Mobile, international roaming page — 10086.cn
What we can point you to is the published channel itself: China Mobile's service number is 10086 and its international roaming hotline is +8613800100186. Ask them directly, in writing, and keep the answer. A rule you have in an email from the operator is worth more than a rule you read on a blog.

All were read on 22 October 2026. Captured copies of these sources are in the archive, with the byte count and a SHA-256 of each response. Three of the provincial notices render their text with script, so the archive marks those captures as partial; the "What we did not verify" section below says what that means.
What we did not verify
- Which tier applies to which country. China Mobile publishes a country-by-country table, but it is laid out in a way that is easy to misread, and we would rather point you at it than restate it wrongly. Check the table on 10086.cn for your own country.
- Rules for issuing a mainland mobile number to a foreign passport holder, and whether an overseas-issued eSIM can be activated on a mainland network. We could not read the operators' current published rules and have not guessed them.
- Any eSIM price on this page. We did not check out on any vendor site. The "from" prices are the vendors' own advertised entry figures as they appeared in their page titles on 22 October 2026, and they are not the price of a realistic package.
- Which networks the travel eSIMs actually use in China, and whether a given package supports 5G, calls or SMS. We did not read the individual plans.
- Whether the free roaming activation has rolled out to every provincial company. We read notices from Hainan, Anhui and Hebei. We did not check all of them.
- Exchange rates, deliberately, and so no cross-currency total.
- The three provincial China Mobile notices are only partially captured. Those pages render their text with script, so what the server returned to our archiver was a near-empty shell. We read the notice text through a search index on 22 October 2026, and the archive folder records the capture as partial. The main roaming rate page, which is the one this page's numbers come from, was captured in full.
