Surprisingly for a developing country, most people in Uganda have at least three cell phones, while people in the United States usually have only one. Ugandans buy these cell phones from different providers to save money on a certain provider's network. Most Ugandans can afford cell phones because the older cell phones start at $7 but smartphones are usually around $1000. In the United States cell phones are widely available, but expensive, smart phones are cheaper than ughanda, but older phones such as slide phones, or flip phones are more expensive. Even the older phones in Uganda can access social media and search engines. Ugandan service providers do not sell contracts for connection, they sell SIM cards with minutes of usage on them. Almost every store in Uganda sells SIM cards, so they are widely available.
In Japan many people have cell phones, even children; 57% of middle school students have smartphones, and 33% of elementary school students have cell phones. The Japanese invented lots of cell phone technologies that the U.S. uses such as games, virtual reality, flashlights, etc. but one thing the Japanese invented for cell phones is a privacy screen to put on a phone, which blocks the view of certain angles other than the users. In Japan providers sell contracts similar to those in the U.S. which you have a monthly bill regardless of if you use your service or not.
In the United States many phone companies sell contracts in which you pay the same provider each month a set price and receive a certain amount of data for use on the line. In Uganda cell providers use pay as you go systems, but the U.S. you pay a set price each month whether you use the data or not, like Japan. Uganda has cheaper data because you only pay for what you use unlike the U.S. But in the United States smart phones are much cheaper than Uganda, but in Uganda flip phones and sliding phones are cheaper than the U.S. In Japan cell phones are about the same price as in the U.S.
