Mobile broadband offers the user the possibility of being virtually anywhere and, provided they have a 3G capable device, or a 3G USB pen adapter for a computer, to be able to access the Internet. Given the possible speed of the 3G network, this guarantees that despite the mobility you still have a quick enough access.
3G broadband cost is widely dependant on the provider you use as each one provides several types of plans for different needs. Some providers offer a mobile broadband pay as you go method that allows people who use the Internet sporadically at best to avoid paying a monthly fee for a service they barely use. For those who do intend to make a stronger use of it, these plans are insufficient.
Cost of wireless broadband will depend essentially of three factors. First, the operator itself since some operators inflate the price more than others. Second, the amount of time you wish to stay online, since some operators base themselves on this limiter.
Third, but far more often the case, the amount of bandwidth available per month. Given that the practical speeds never really reach the 7.2Mbps promised by most operators, a insanely huge bandwidth limit is not necessary, but with sometimes limits as low as 500Mb it may just not suffice even for common internet usage along a whole month.
Verizon mobile broadband cost is relatively cheap and they do include plans for unlimited bandwidth which would virtually allow you to stay online 24/7 and download whatever you well wished. Clearly the advantage here is that you may be in contact reach, depending on your equipment, both by internet and phone.
Of course, Verizon may not provide full bandwidth speed, which may lead you to want to try and search other operators. Prices these days are fairly competitive, but it's all the small deals that you must observe like the bandwidth limit or the allowed online time. Both are crucial values while searching for mobile broadband best deals.
