First safe move
Start here: Make mobile data work before the first airport-to-hotel transfer.
Phone and apps
In short
Treat eSIM, VPN, roaming, Wi-Fi, and home-SIM SMS as separate dependencies. A travel eSIM can solve mobile data, but travelers should still prepare blocked-app access, bank SMS, hotel contact, and offline transfer details before landing.

Editorial check
Phone, eSIM, maps, and app answers were reviewed with the current connectivity comparison and setup guidance.
Current eSIM provider routing, device compatibility, carrier lock status, roaming cost, VPN availability, home-number SMS behavior, and app access requirements. Provider plans, device compatibility, app availability, roaming behavior, and network routing can change before departure.
Recovery template
Start with the immediate move, keep a human or offline fallback, and only rely on live rules after checking the official operator, provider, or source.

Start here: Make mobile data work before the first airport-to-hotel transfer.
Fallback path
Use saved offline hotel details, home-SIM SMS or roaming, hotel Wi-Fi, provider support, and screenshots until mobile data is stable again.
Do not assume
Do not treat this answer as final live proof. Do not use as proof of current network access, app availability, provider routing, or device compatibility without checking the live provider and device state.
Source boundary
Current eSIM provider routing, device compatibility, carrier lock status, roaming cost, VPN availability, home-number SMS behavior, and app access requirements.
Action path
A practical answer should leave the traveler with a few moves they can actually make before the trip or at the point of friction.
Make mobile data work before the first airport-to-hotel transfer.
Save hotel, route, and support details offline.
Treat map, message, and translation apps as dependencies, not decorations.
Official source
These facts are read straight from the operator's own page, so you can check each one at the source rather than take it on our word.
This travel eSIM is a data line only: no phone number, no calls, no text messages — in the provider's own words
Holafly states outright that its China eSIM comes with cellular data only, that it is not an eSIM with a phone number, and that it includes no local number for calls or text messages. That is the published reason a bank's SMS code cannot arrive on the travel eSIM: there is no number for it to be sent to. The statement binds this provider's product; whether another provider's China plan carries a number is that provider's own term to check, not something this page generalises.
Where in the source: Product-scope clauses: “The China digital eSIM only comes with cellular data.” / “it is not a China eSIM with a phone number” / “It does not include a local phone number for phone calls or text messages”
Your home SIM can stay in the phone alongside the eSIM, which is where the SMS half has to live
The same page states that on a dual-SIM phone or an Apple device the physical SIM and the eSIM can be used in the same device. So keeping the home number present for verification codes is a published capability of the product, not a workaround. What the page does not say is whether an SMS will actually arrive on that home line abroad, or whether home-carrier roaming has to be switched on for it to — that is a question for your home carrier, and this layer does not answer it.
Where in the source: Dual-SIM clause: “If you are using a dual SIM phone or an Apple device, you can use your physical SIM card and your eSIM in the same device.”

The wallet's own condition on your phone number is that it can receive SMS verification codes — nothing else
Asked whether a Chinese mainland (+86) number is needed, the help page answers no: an international number is fine as long as it can receive SMS verification codes. Put next to the eSIM's data-only term above, this is the whole of the dependency this answer describes — data arrives on the eSIM, the code arrives on the home number, and neither substitutes for the other.
Where in the source: Q&A clause: “Do l need a Chinese Mainland (+86) phone number?” — “No. You can use your international phone number as long as it can receive SMS verification codes.”
Payment operator's own help page, not a regulator's page: Tencent / WeChat Help Center — the operator's own consumer help page for its international-card terms — Guide to Add and Use International Cards with Weixin Pay (source evergreen operator help page carrying no publication date; body identical to the 2026-07-24 read; read September 19, 2026)
A second provider makes no China-specific statement either way about a number or SMS
Airalo's China page says nothing about a phone number, SMS, roaming or dual SIM for this plan; the only “data only” wording on it is the caption of a filter control, not a statement about the China product. The two pages therefore differ in what they publish, and that difference is itself the point: whether your eSIM carries a number is a term to read on your own provider's page, and where the page is silent it is not answered.
Where in the source: Filter caption only: “Displays all data only eSIMs for the location when selected.” — no China-plan statement on number, SMS, roaming or dual SIM.

The blocked-app half of this answer has no official source, and that is why it stays a dependency rather than a fact
The regulation that administers international networking lists no service, site or app and says nothing about reachability, and no other official page publishes such a list. So “prepare blocked-app access” on this page is a planning instruction with no sourced answer behind it — which is exactly why it is listed as a separate dependency from data, SMS and roaming, each of which does have a publisher of record above.
Where in the source: The regulation contains no service list; 第七条 addresses protection of users' communication freedom and privacy, not reachability of named platforms.

What this source does not settle: This layer sources three of the five dependencies this answer names — data, the home-number SMS route, and the fact that the wallet's only phone-number condition is receiving a code — and states explicitly that the VPN and blocked-app dependency has no publisher of record: the regulation opened here lists no service and no official page does, and both operator pages are silent on it. It publishes no workaround and nothing here should be read as guidance about circumventing anything. Holafly's data-only term is Holafly's, attributed by name and not generalised to China eSIMs as a class; Airalo's page is recorded as silent, never as confirming or denying a number. Whether an SMS reaches a home line abroad, and whether home-carrier roaming must be on for it to, is a home-carrier question the operator page does not answer and this layer does not either. A local SIM on a passport as a fallback is already cited from 工信部令第25号 on this site's Google Maps answer and is not re-counted here. Hotel contact, offline transfer details and roaming cost — the rest of the page's checklist — stay operational and uncited. Product terms change without notice; each page governs on its own read date, and the regulation's date is the 2026-08-22 pass in which it was opened.
