As the technology is advanced and economic grows up, everyone has one smartphone or portable device like Ipad in these days.We can contact everyone in this world with application like "whats apps" or "Skype". However, using cellphone in other world with normal "cellphone signal" is called roaming system has some problems with signals and charging so much money. In my cases, i have two cellphone in Korea and united states because using roaming system is much more expensive that i've been expected.
So, i would make a company that provide just "4G" world widely so that we can use cellphone world widely without problem in connecting and financing problem. It is take advantage of Smartphone.
This is a pretty lofty idea. I know that a lot of cell phone carriers and manufacturers are attempting to do similar things as they come together and try to create more standards so that a cell phone will work internationally. A great start to getting into this space is to potentially start a website that outlines by phone what countries it will or will not work in.
