我使用的是戴尔 Precision M4500。我发现电池槽下面有一个SIM卡槽，我想它是用来使用移动宽带接入的。
我通常通过 Android 手机的绑定信号连接到互联网，我认为将 PC 配置为使用手机中的 SIM 并直接访问互联网可能会更容易。
我需要确认的第一件事是，实际上有一个宽带调制解调器或某些设备可以连接到3G，而不仅仅是计算机骨骼中的插槽。
我尝试过lspci但lsusb无法识别任何可能是 3G 调制解调器的设备。
这里的输出

有人可以帮助我了解我想做的事情是否可能吗？
答案1
戴尔笔记本电脑有带 3G 芯片组和不带 3G 芯片组的版本。无论是否安装芯片，该插槽都可用。看来您没有 3G 硬件。您可以打开笔记本电脑进行检查。 wwan/3g 芯片通常位于蓝牙和 WiFi 芯片旁边，并且是可拆卸的。
