Huawei modem:
A phone provider acting as an ISP gives you access to internet via a huawei modem.The technology used is similar to taking a phne call or better using a phone to browse the internet.The ISP can restrict bandwidth so how do you overcome the restrictions? I know you can unlock the modem.

code so that it uses different sim cards or a variety of ISP but how woul you hack the modem to increase bandwith or in other words how can i crack the modem deeper to letting it intercept signals and shit
