Week 4- hardware components.

The hard work components really impotant for my company. To make cellphone be available to "mobile data" we should develop the chip to we should put in the cell phone. we are using "USIM chip" right now but it works just in one country or with the one mobile company. To use "3G" system, make usim chip to available gets signal from two or more mobile company.

my company provide only "3G" or "4G" plan to the customer. However, it is hard to support all the cutomer with only our signal. we should corporate with the mobile company that has mobile data system like Verizon before we complete to make the signal center on over the countries and world. Before that, we have to use other companies signal first and provide the service with them. Even we have to corporate with other countries companies to provide world-wide service. In other words, we have to develop the special "USIM" chip first that can use with the several company's signal freely.
