Gsm Ussd Android MetroPcs Codes

                      CODE 1: *#06# (REVEALS IMEI NUMBER)

When you type *#06# on any mobile phone or tablet that uses SIM cards, the IMEI number of the device is displayed. The IMEI is a unique number that carriers and manufacturers use to identify a device but it can also be used to generate unlock codes to remove the SIM lock. Unlocking lets you use a mobile with a SIM card from another service provider should the device be currently locked to a specific provider. For example, if a Samsung Galaxy is locked to AT&T, then an unlock code can be generated based on the IMEI number in order to unlock it. Once unlocked, you can use it with a SIM card from another carrier such as MetroPcs . One way to determine whether your device is locked is to insert a SIM card from another provider and see whether the SIM is accepted.

            

                 CODE 2: #31# (DISABLES OUTGOING CALLER ID)

The code #31# hides your phone number when you call someone but it only works on the call you are currently making. Some Galaxy phones require that you combine the code with the phone number that you want to dial (for example #31#phonenumber and then tab the Call button). Some other Galaxy models require that you type the code, tap the Call button, and then dial the number. Try calling your home phone number to see which way it works on your particular model.

CODE 3: *#21# (CHECKS CALL FORWARDING SETTINGS)

Enter *#21# and then tap the Call button. The menu that pops up shows you what your Call Forwarding settings currently are.

CODE 4: *#30# (CHECKS INCOMING CALLER ID SETTINGS)

When you enter this code and tap Dial, a menu shows up, telling you whether your phone is currently displaying the caller ID of incoming calls correctly. It’s also a test to see whether the incoming caller ID function works.

CODE 5: *#31# (CHECKS OUTGOING CALLER ID SETTINGS)

By entering *#31# and then tapping the Dial button, your phone will show you what your current outgoing caller ID settings are. For example, it shows you whether you are hiding your phone number the next time you call someone. It is also a test to see whether the outgoing caller ID function works.
