Due to differences in telecom operators and software usage policies across countries, the following APNs (3gnet、mobile、ctm-mobile、CTExcel、smartone、mobile.three.com.hk) do not support TikTok and may not support certain applications, such as AI apps like ChatGPT or Gemini.

We suggest you turn off the device when not in use, and turn off auto-update and auto-backup functions (such as push mail) on your phones and tablets, and offline or log out of the website after browsing. Suppose the cellular company detects that an excessive amount of data was consumed in a short period. In that case, they have the right to lower or disconnect your connection speed without notifying iVideo in advance. To have unlimited data, you need to keep the advanced mode on. There will be no refunds or compensation if this occurs. How do I turn off auto-update & auto-back on my mobile devices?
