Businessmen prefer phones that are stable and have a sleek design.
They need to have all the intuitive planning functions as well as an easy to manipulate conversation software.
If you live in an area that doesn't have 4G coverage, there's no advantage to a 4G phone.
In fact, you'll have serious battery life problems if you buy an LTE phone and don't disable 4G LTE, as the radio's search for a non-existent signal will drain your battery quickly.
4G coverage is only going to get better, and that's where the carriers are spending most of their money right now.
You can assume that all 4G phones also support your carrier's 3G and 2G networks as well. There are a few reasons you might still settle for a 3G phone.
In that case, make sure to get the fastest 3G phone possible.You can perform several functions such as sending and receiving emails, chatting, streaming online videos, taking pictures and sharing on social media, use map for navigation, the phone GPS helps tell your location and more.When choosing to buy the right smartphone, it's essential that you consider not only the price of the product but also its functions.The International Telecommunications Union, a standards body, tried to issue requirements to call a network 4G but they were ignored by carriers, and eventually the ITU backed down.
4G technologies include HSPA 21/42, the now obsolete Wi MAX, and LTE (although some consider LTE the only true 4G of that bunch, and some people say none of them are fast enough to qualify.) There's a big difference between 4G LTE and other technologies called "4G" though, and it's most visible in upload speeds.On Verizon and Sprint, you want to check that it supports "EVDO Rev A." On T-Mobile and AT&T, you want the highest class of HSPA possible: if not 42 or 21, then 14.4.
