另外:
SIM box
从英文翻译而来-SIM盒是用作VoIP网关安装一部分的设备。它包含许多SIM卡,这些SIM卡链接到网关,但与网关分开存放和存储。SIM盒可以安装不同移动运营商的SIM卡,使其可以与位于不同位置的多个GSM网关一起运行。
不知道这个东西能否使用?

Some carriers attempt to detect and deny service to SIM boxes through various means, including cancellation or restriction of service to identified SIMs. SIM box operators often swap SIMs to replace restricted ones. They may also rewrite the International Mobile Equipment Identity (IMEI) of the SIM box, often using randomized IMEIs in ranges of or those assigned to common mobile phones to evade detection.
中文大意:有的运营商会想办法检测SIM盒子并且拒绝服务,把盒子的IMEI虚拟成手机所用的IMEI范围可能可以逃避检测。 |
