Hi. There are two ways to show a frequency band:

1.) is to show the #### MHz range. That's a 3- or 4- digit number with MHz

2.) is to show a band number like B ##. That's a 1 or 2- digit number with B or band

Every MHz translates into different bands. You can see this here for 3G and 4G/LTE.

The problem with the old way of expressing it in MHz that e.g. the 700 MHz spectrum has different up- and downlink ranges in America and Europe/Asia/Pacific. That's why for 4G the second way is preferred. 700 MHz is band 28 in Asia or bands 13-17 in the US.

With NTT Docomo where the most offers are on, you will have 3G on 2100 (B1) on your device in the cities and towns, but not on 800 (B18) in the countryside. You also have about 50% of their LTE bands. So again, you will have good coverage, but may be not everywhere.
