FCC Warning
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This
device may not cause harmful interference, and (2) this device must accept any interference received, including
interference that may cause undesired operation.
Any Changes or modifications not expressly approved by the party responsible for compliance could void the
user's authority to operate the equipment.
Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to
part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference
in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more of the following measures:
-Reorient or relocate the receiving antenna.
-Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-Consult the dealer or an experienced radio/TV technician for help.
RF warning:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This
equipment should be installed and operated with minimum distance 20cm between the radiator & your body.

1. Introduction
This document describes electrical specifications, mechanical information, interfaces application and
manufacturing information about SIM5800 module. With the help of this document and other application notes or
user guide, users can understand SIM5800 well and develop various products quickly.
2. Overview
SIM5800 is a multi-mode and multi-band wireless smart module, which is based on MTK MT8321 platform. It
includes baseband, memory, RF front end and required circuitry to support rich multimedia features, global
location-based service, wireless connectivity, and air interface standards including WCDMA, GSM/GPRS/EDGE.
With higher integration to reduce PCB surface area, time-to-market, and BOM costs, SIM5800 will help drive
wireless products adoption in more industry around the world.
There are 210 pins on SIM5800 which provide most application interfaces for users’ board.
