Fresh connection, zero noise.
Plug a small QDC507 LTE dongle into a Pixel Tablet, and Lemon Call turns the tablet into a phone. You can make and answer calls, send and receive texts (Chinese and emoji included), keep a call history and share the SIM’s mobile data. There’s no root, no extra computer and no cloud service in between.
The dongle is a tiny Linux computer with its own modem. Lemon Call talks to it directly over USB. It sets up a brand-new dongle with one tap and carries the call audio itself. It can also switch on VoLTE, which a roaming SIM needs to make and receive calls.
A Windows version comes as a single LemonCall.exe, with no Java needed.
Lemon Call 檸檬通話：把 USB LTE 網卡變成電話
Fresh connection, zero noise.
把一枚小小的 QDC507 LTE 網卡插進 Pixel 平板，Lemon Call 就能讓平板變成電話：撥打和接聽電話、收發簡訊（支援中文和表情符號）、保留通話紀錄，還能分享 SIM 卡的行動數據。不需要 root，不需要另一台電腦，也不經過任何雲端服務。
這枚網卡其實是一台內建數據機的微型 Linux 電腦。Lemon Call 透過 USB 直接與它溝通：全新的網卡按一下即可完成設定，通話聲音也由 App 自行傳送。漫遊 SIM 卡必須開啟 VoLTE 才能撥打和接聽電話，App 也能一鍵開啟。
Windows 版是一個獨立的 LemonCall.exe，不需要安裝 Java。
