15世紀末(卡克斯頓),"能夠移動的,能夠被移動的,不固定或靜止的",源自14世紀的古法語 mobile,源自拉丁語 mobilis "可移動的,易於移動的; 鬆散的,不堅固的",比喻地指"易彎曲的,靈活的,易受影響的,敏捷的,迅速的; 易變的,不穩定的,善變的",縮寫形式爲 *movibilis,源自 movere "移動"(源自 PIE 詞根 *meue- "推開")。1927年開始出現了社會學意義上的"能夠進入不同社會層級的"含義。1936年開始記錄了 Mobile home "永久停放並用作住所的大拖車"。1983年開始出現了 Mobile phone。

伊利諾伊貝爾汽車電話上輸入的長途號碼在顯示屏上變紅。確認數字無誤後,我按下電話上的發送按鈕。熟悉的嘟嘟聲從聽筒中傳出。然後,在這個芝加哥郊區的半個街區還沒過去之前,我就與我的紐約辦公室取得了聯繫。["隨身攜帶的電話",《大衆科學》雜誌,1983年10月]
