Most mobile networks worldwide use portions of the radio frequency spectrum, allocated to the mobile service, for the transmission and reception of their signals. The particular bands may also be shared with other radiocommunication services , e.g. broadcasting service , and fixed service operation.
When distributing initial spectrum licenses in a band the FCC divides the US geographically into a number of areas. [1] A mobile operator (or other interested party) must bid on each area individually. A license owner can use any technology within the licensed area and frequency range subject only to the band rules defining various analog limits.
Apart from their main spectrum holdings across large regions in the country (listed below) the major US carriers (AT&T, Sprint, T-Mobile & Verizon) also hold various Cellular Market Area (CMA) and/or Economic Area (EA) licenses for the AWS 1700 band, as well as Major Trading Area (MTA) and/or Basic Trading Area (BTA) licenses for the PCS 1900 band.

The Asia-Pacific Telecommunity (APT) band plan is a type of segmentation of the 612–806 MHz band (usually referred to as the 600 MHz & 700 MHz bands) formalized by the APT in 2022–2023 and 2008-2010 respectively [1] and specially configured for the deployment of mobile broadband technologies (e.g. most notably Long Term Evolution, LTE).
Telecommunications policy addresses the management of government-owned resources such as the spectrum, which facilitates all wireless communications. There is a naturally limited quantity of usable spectrum that exists, therefore the market demand is immense, especially as use of mobile technology, which uses the electromagnetic spectrum, expands.

Mobile phones use geographic area codes (two digits): after that, all numbers assigned to mobile service have nine digits, starting with 6, 7, 8 or 9 (example: 55 15 99999–9999). 90 is not possible, because collect calls start with this number.
