Giga.Tel does not provide a China eSIM that includes a phone number or SMS capability. All of the plans sold by the provider are data‑only, so travelers cannot receive or send traditional SMS messages or place calls using a local phone number.
For voice and messaging needs, users can rely on popular Internet‑based services such as WhatsApp, Telegram, and iMessage, which typically work over the data connection. However, China sometimes blocks or restricts certain VoIP applications, so it is advisable to verify that the services you plan to use are accessible in China before purchasing a Giga.Tel eSIM.
