Just to clarify as this seems to always confuse people... Samsung defines :
1GB= 1 billion bytes (decimal)
The system is binary, so what the computer sees :
1GB = 2^30 =1,073,xxx,xxx bytes
GB =Gigabyte
There is also "gibibyte" which some refer to as the binary.
To make things more confusing, ram is in power of 2. So 1GB ram =1,024 MB = 1,073,xxx, xxx bytes
Verizon data usage is measured by 1GB =1,073, xxx, xxx bytes
To make matters even more confusing, bandwidth speed is usually referred to in bits per second, 1 byte =8 bits. Verizon advertises up to 12mbps, or 12 megabits /sec. Which is 1.5 megabytes /sec
