gosimless does not provide China eSIM plans that include a phone number or SMS capability. All available China eSIMs from gosimless are data‑only plans. Travelers who require a phone number or inbound and outbound SMS will need to seek another provider or alternative solution.
With the data connection, popular VoIP apps such as WhatsApp, Telegram, and iMessage can usually be used for calls and messaging. However, some destinations may block or restrict access to specific apps or VoIP services, so travelers should verify that the apps they rely on are available in China before purchasing a plan.
