Textr Go App is not currently available in Mainland China. However, you can still use the Textr Go web version to send texts and receive verification codes. 

If you want to download the app and use the full features of the Textr Go, you need to change your App Store region to an area outside Mainland China, such as the United States, Canada, or Hong Kong. This will enable you to download and install the app. For help with changing your App Store region or downloading the app, please contact our customer support at support@textrapp.com.
