Make data, apps and verification work together
A working data connection, access to an app and access to your verification number are three separate checks.
CTC source review: 2026-11-11. Adapted for this comparison; this is not a new check of provider terms or live inventory.
| Need | What to prepare | What the eSIM does not establish |
|---|---|---|
| Navigation | Save your hotel’s Chinese address and a route backup. | That every map app works identically on every network. |
| Payments | Set up the chosen payment app and a backup before travel. | That your card or account will pass the app’s checks. |
| SMS codes | Retain access to the number registered with your bank or app. | That a data-only travel plan supplies your home number. |
| Essential apps | Ask the provider about the apps you require. | Guaranteed app access or independently measured speeds. |
