In Austria, the A1,
T Mobile, Orange, and Three HSDPA networks operate. HSDPA stands for
"High-Speed Downlink Packet Access" and the upload speed is up to 5.8
Mbit/s. High Speed Uplink Packet Access (HSUPA) is a transmission method of the
UMTS mobile radio standard that allows higher data rates in the uplink and
reduces the round trip time (often referred to as ping). HSUPA category 6 can
achieve up to 5.76Mbit/s and category 9 (Release 9) can achieve up to 23
Mbit/s. HSUPA is part of Release 9 of UMTS. The control menu includes

A Media Access
Control (MAC) address is a globally unique identifier assigned to network
devices and is often referred to as a hardware or physical address. MAC
addresses are 6 bytes (48 bits) in length and are written in MM:MM:MM:SS:SS:SS
format. The first 3 bytes are the ID number of the manufacturer, which is
assigned by an Internet standards body, and the second 3 bytes are the serial
number assigned by the manufacturer.

The Customer
Service Code (CSC) plays an important role in the operation of your mobile.
Different countries have different standards for both voice and data
communications to a cell phone tower. Although most countries follow the
international standards for WiFi connections, there are variations from the
standard. The CSC code ensures that your mobile device complies with the
standards of your country and your cell phone operator. The CSC code also
determines the source for firmware updates via FOTA or Samsung Kies, build
time, and change list number.
Codes to launch
various factory tests include:
*#*#0283#*#*

GSM codes for
Xiaomi Redmi Android phones include changing PIN settings by setting up a
Personal Identification Number (PIN) on your SIM to stop others from using it
when it’s switched off or been taken out of your device. The acronym PUK is
derived from the term PIN Unlocking key. The PUK or PUC number is the PIN code
needed to unfreeze the sim card. To change PIN, enter **04*, then enter the old
PIN and twice the new PIN. To change PIN2, enter **042*, then enter the old
PIN2 and twice the new PIN2. To unlock SIM card (PIN), enter **5* then enter
the PUK and new PIN twice. To unlock SIM card (PIN2), enter **052* then enter
the PUK2 and new PIN2 twice.
