Skyalo does not offer a China eSIM plan that includes a phone number or SMS capability. The provider only sells data‑only plans for travelers traveling to China, so there is no option for inbound or outbound calls or text messages through the carrier network.
Travelers can still use common VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages; however, some destinations may block or restrict specific apps or services. It is advisable to confirm that the messaging or calling apps you rely on are accessible in China before purchasing a Skyalo data plan.
