2. 順道VPN試用激活
Activate Trial

于通行證書版面 創建一張屬於你自己的《免費通行證書》,其詳情將會被自動複製到設備的剪贴板。在你與 Alice 的聊天對話框中黏貼、發送該詳情給她,然後等待她簽署它。Alice 完成簽署它後,你會在對話框中收到一個互動信息按鈕,你按下該按鈕即可完成導入該已簽署的《免費通行證書》到設備內。

Go to the Certificate page to create a FREE CERT of your own, which details will be automatically copied to your device’s clipboard. Paste and send the details via the dialogue box between you and Alice and wait for her to sign it. Once Alice signs it, you will receive an interactive message button in the dialogue box. You press the button to import the signed FREE CERT to your device.

3. 開始使用順道VPN
Start Surfing on LubeVPN

在「設定」,撥亮 順道VPN的切換鍵請求服務授權。如果授權成功,切換鍵轉成綠色

In General Settings , turn on the LubeVPN toggle switch to request authorization to VPN service. Toggle switch turns to green if the authorization succeeds.

防止被殺後台: 由於移動終端的操作系統存在節能和運行內存回收機制,若後台同時運行進程較多,系統會自動將優先級較低的應用進行關閉(俗稱:「被殺後台」),騰出電源和內存以保證較後啟動的應用可以保持正常運行。為了讓你的西蒂姆(Citum)客戶端內的即時聊天工具及時收到信息與 順道VPN《通行證書》的推薦人簽名,有兩個辦法供你選擇防止客戶端被殺後台:1、撥亮位于 順道VPN切換鍵使之呈橙色 或綠色 ;或 2、請在網上搜索一下你所用的手機型號該如何防止其應用 app 被殺後台,按其指示步驟操作將 Citium 客戶端應用 app 在後台運行。



Keep App Running in the Background: Operating systems of mobile devices have battery-saving and memory-recovery mechanisms. If a lot of background processes are running at the same time, the system will automatically shut down the lower priority applications to ensure ample battery life and memory capacity to enable the rest of the applications to run normally. In order for the instant messaging chat in the Citium Client to receive messages and the signing of LubeVPN CERT (digital certificates) in a timely manner, you are highly suggested to choose to operate one of the options below: 1. Turn on the toggle switch of LubeVPN in so that it shows color orange or green ; or 2. Search your device model online to find out the steps to make its app running in the background. Follow the steps to make the Citium Client app run in the background.
