N93i open engineering mode

In standby mode, enter *300 1# 12345# and wait 1 sec to enter quasi-engineering mode. The specific projects are as follows:

1, NAM 1 (personal option)

Your own number, allowing you to set your mobile phone number.

ALPHA TAG (mobile phone identification), you can enter a name.

Emergency (emergency dialing), you can modify the original numbers such as 1 12, 1 10. There is always a number of 10 that can be set, and even the home number can be set when the phone is locked and cannot be dialed.

SERVICE NUMBER (service number), which can be set to five, generally refers to the customer service number of China Unicom, etc. , you can set it yourself.

CDMA settings (CDMA includes primary CDMA channel A and secondary CDMA channel A and secondary CDMA channel B (primary CDMA channel B) and network cable (national cable), etc. It is best not to change it, so as not to affect the use! ! ! ! Be sure to remember.

2.SW version (mobile phone version number), mine is VJ 175v0200. NEP 17- 12-03RH48。

3, serial number (serial number), which is actually equivalent to the serial number of GSM mobile phone, should be the same as the number behind the mobile phone.

4. It has been programmed (date of purchase and use). Remember that it cannot be changed after input. Carefully consider whether to input it.

5, field test (field test, engineering mode), you can choose to open or close, the default is closed, for your battery life, or close it, a bit like engineering mode.

6. UIM ID (ID number of UIM card) is for viewing only and cannot be changed.

7. The usage of 7.UIM ID is to check (generally 1), that is, UIM card has only one phone number.

8.UIM revision (UIM card version), for viewing only.

9. The name of the service provider (network service provider ID) is actually the new time and space of Unicom.

After viewing all the items, you can quit without turning off your computer. The mobile phone automatically searches the network again.

Please note: Be careful not to modify other options except mobile phone number, mobile phone logo and purchase date, so as not to affect your use and warranty rights.

Enter the engineering mode: in the quasi-engineering mode, select the No.5 field test, turn it on, and then turn it on. The last item on the mobile phone menu will be NET MONITOR.

The monitoring data of engineering mode is realized by code. Select menu-Network Monitor, enter the engineering mode, and change it to the corresponding code in 0000 state, so as to view data or information, for example:

3 10 1, comprehensive test

The first number (not a number, the word is missing) is the status of the software in the control layer of the mobile phone.

The second number is the channel number (carrier frequency) (only 283 in a small place).

The third number is actually two numbers (usually sc), where S stands for slotted mode (that is, the mobile phone works at intervals to save power), and if it is n, it is non-slotted mode (always working).

C is cellular 800 (domestic 800), and if it is P, it is PCS.

In the second line, the first number is PN offset (used by mobile phones to distinguish base stations), the second number is still two numbers, the first paging channel number and the second paging channel rate, where f is the full rate and h is the half rate.

In the third line, the first one is the received power (the smaller the absolute value, the better, generally greater than -80), and the second one is the transmitted power (generally -70 means no transmitted power). The unit is dbm.

The fourth line, the first service channel option (meaningless in standby, talking 3, surfing 33), the second active set number (that is, the mobile phone is talking to several cells), and the third forward frame error rate. It's all zeros.

Effective when using the traffic channel.

3202, network signal testing, specifically signal strength and base station ID.

6202 is to monitor the battery information, and the parameters lb, lp, lf and cd are in milliamps, milliamps, milliamps and milliamps-hours respectively.

The ringing volume is 5, the melody is futuristic, and the call volume is one grid apart.

Standby (no light): 2, 2, 0, 0

Unstable standby network signal (no light): 2, 2, 0, 0

When the caller is not connected (indicator light): 350,350,100,0

When the called party is not connected (vibration light rings): 450, 450, 250, 0.

When the called party is not connected (light): 300,300,100,0

When the called party is not connected (vibrating light): 300, 300, 50, 0

When the called party is not connected (the light rings): 125, 125, 100, 0.

SMS (vibrating light): 200, 200, 0, 0

Call (without lights): 250, 250, 0, 0

Game bounce: 122, 122, 120, 0.

When monitoring the current, press the "Hang Up" key to immediately monitor the current in the previous state.

Analysis: lf is related to lighting, while lb and lp are related to energy consumption except lighting!

For other information, press the up and down arrow keys to test. You can test all the information of mobile phone and UIM card through engineering mode. I am not very clear about the information about each code. You can have a test. If you find something new, please reply and learn from each other.

If you want to exit the project mode, just enter the last item in the mobile phone menu (project mode), enter 0000, and press the left button to confirm, without restarting the mobile phone. In engineering mode, it will affect the standby time.
