{{isEng?'FAQ':'常見問題'}}
使用 VoLTE有甚麼好處?
VoLTE 可提供高速接駁、高清話音通話,讓你在通話期間同時使用流動數據,並提升你的通訊安全。

另外,在已停用 2G / 3G 網絡的地區(如台灣、澳洲、美國等),如未啟用 VoLTE,話音通話可能無法使用。

因此,無論在本地或海外使用,VoLTE 對於確保話音通話不中斷都同樣至關重要。
為甚麼透過 VoLTE 通話會更安全?
當你使用 VoLTE 撥打話音通話時,通訊內容會透過 4G LTE 或 5G 流動網絡傳送。相較於較舊的流動網絡,這些新一代網絡具備更高級別的安全防護機制,採用更先進的加密技術及更完善的網絡身分識別保護,有助加強通話的安全性。
我已跟隨此網頁內的指示,但未能在手機「設定」中找到 VoLTE,為甚麼?
如你無法在手機「設定」頁面中找到VoLTE,有機會是基於以下原因:
  • 手機型號不支援 VoLTE
  • 作業系統版本過舊
  • 新版本系統已預設啟用 VoLTE(無需手動開啟)

我們建議你更新手機系統或重新啟動手機,並參考手機/裝置清單,查看手機型號是否支援 VoLTE。
使用 VoLTE 需要額外收費或扣數據嗎?
不需要。VoLTE 話音服務不涉及任何額外收費或數據扣除。
雙卡或 eSIM 手機可以用 VoLTE 嗎?
請放心,手機上的VoLTE功能,不會因雙卡或 eSIM 規格而有影響。建議你跟隨此網頁內的指示,在手機「設定」中啟用 VoLTE。
What are the benefits of using VoLTE?
VoLTE provides lightning-fast call connection, HD voice quality, allows you to use mobile data while on a call, and enhances your communication security.

In regions where 2G / 3G networks have been shut down (e.g. Taiwan, Australia and United States), voice calls may not work without VoLTE.

Therefore, enable VoLTE is essential to ensure uninterrupted voice calls, both locally and overseas.
Why is making calls via VoLTE safer?
When you make calls using VoLTE, your communication is transmitted over 4G LTE or 5G mobile networks. Compared with older mobile network technologies, these newer generations offer a higher level of security protection with advanced encryption and enhanced identity protection technologies, helping to keep the calls more secure.
I have followed the instructions on this webpage, but still cannot find the VoLTE option in my phone’s Settings. Why?
If you cannot find the VoLTE option in your phone’s Settings, possible reasons include:
  • Your phone model does not support VoLTE
  • Your operating system version is outdated
  • VoLTE is already enabled by default in newer systems (No manual activation is required)

We recommend updating your phone’s operating system or restarting your device. You may also refer to Handset/Device List to confirm whether your phone model supports VoLTE.
Is there any extra charge or data usage for VoLTE?
No. VoLTE voice calls do not incur additional charges and do not consume mobile data.
Can VoLTE be used on dual-SIM or eSIM phones?
Rest assured that your phone’s VoLTE function will not be affected by dual‑SIM or eSIM configurations. We recommend enabling VoLTE in your handset’s Settings according to the instructions on this webpage.
