The E220 connects to the computer with a standard Mini USB cable. The device comes with two cables, one short and one long. The long one has two USB A interfaces, one used for data and power and the other optionally only for assistance power in case the computer is not able to provide the full 500 mA (milliamperes) required for the device to work from one USB interface only.
External wireless modems include connect cards, USB modems, and cellular routers. Most GSM wireless modems come with an integrated SIM cardholder (i.e. Huawei E220 , Sierra 881.) Some models are also provided with a microSD memory slot and/or jack for additional external antenna, (Huawei E1762, Sierra Compass 885.) [ 62 ] [ 63 ]
