Quick answer: Twilio SMS is Unavailable for mainland China production stacks. Since Twilio's PRC messaging restrictions notice (last updated March 30, 2021), China SMS is not a workable path — use China-licensed providers such as Alibaba Cloud SMS, JPush SMS. Availability in China: Unavailable.
Availability in China: Unavailable
Chinaready marks Twilio SMS as Unavailable for mainland China. Twilio's official PRC messaging restrictions (last updated March 30, 2021) define the China messaging constraints that make reliable production delivery impractical. Treat that date as the cutoff for planning: do not depend on Twilio for China SMS; use a China-market SMS option instead.

The shortlist below focuses on China-licensed SMS providers that can cover verification and notification workflows inside mainland China — including Alibaba Cloud SMS and JPush SMS (极光短信 / JSMS).
Mapped China-ready candidates
Alibaba Cloud SMS provides SMS messaging services for verification and notification workflows, including phone-number OTP login.
China context: China-market SMS for verification and notifications when Twilio SMS is unavailable. Commonly used to power phone-number OTP login alongside WeChat Login when international apps add mainland login options — Apple Login itself remains usable, but Chinese users often prefer phone or WeChat login.
JPush SMS (极光短信 / JSMS) provides China SMS verification, notification, and marketing delivery with carrier-integrated channels and REST APIs.
China context: Jiguang SMS product for mainland China when Twilio SMS is unavailable. Covers text/voice verification codes, template notifications, and marketing SMS over China carrier channels, with REST API and console access. Strong fit for teams already using JPush who need SMS fallback or standalone SMS OTP/notification workflows.
No for mainland China production stacks. Chinaready labels Twilio SMS as Unavailable. Since Twilio's PRC messaging restrictions notice (last updated March 30, 2021), China SMS is not a workable production path — plan a China-licensed SMS provider instead.
Chinaready Landscape currently maps Twilio SMS to Alibaba Cloud SMS, JPush SMS. Prefer China-licensed SMS providers such as Alibaba Cloud SMS and JPush SMS for verification codes and notifications. Replacement fit varies by product, so treat this as a research shortlist rather than a one-to-one endorsement.
