    HI Zohail

    I tried that and it still does not work. It seems there are lots of people with similar problem. What is the major course of this problem??? Any other possible solution?

    ok try to reset ur phone like this first ok dont worry it will be solved

    + To restore your phone to the original factory default settings, press
    the Menu button, then go to Tools, Settings, General, Factory settings.
    Here you need to enter the lock code (generally 12345). After the
    reset, the device may take a longer time to power on.

    + To hard reset/format Nokia N72 (all data will be lost), follow the below mentioned steps:

    1. Turn off the mobile phone.
    2. Press and Hold the following three buttons: the green Call Answer button, the “*” button, and the number “3? button.
    3. While holding these three buttons, press the power button to switch on the device.
    4. Release your fingers when the screen displays the Nokia Logo and the language selection menu further.

    or try this

    Master reset
    1) *#7370#, then enter 12345 (This is the default security code unless the user has changed
    it) and then Yes. The phone then wipes all apps and phonebook contacts
    on the internal memory.

    One shud work or all

    let me know if doesnt work

    if after RESET again same problem then ur Network Sim Card Slot is faulty it the IC concerned is faulty but it is not a major repair thing very cheap but pls check all first and also before any hardware repairs pls update ur phone firmware from

    download the Update Application and drivers for ur phone and install and conenct to internet and get the latest Firmware for ur phone if it dosnt help then go for hardware repairs

Factory resetting the phone will do absolutely nothing with this problem

There are 3 causes of Sim Card Registration Failed, when you first turn on the phone, the sim card attempts to connect to the network if it can not do this it gives a message like Sim Card Registration failed.

1, The sim card is turned off (is it Orange) if you have had the sim card for a while and it hasnt been used they will turn it off, you need to contact them from another phone to get it turned on or get a new sim card.

2, The phone has a hardware reception problem, when it attempts to register itself with the network it can not... There is a reception problem and it requires repairs, this isnt really an easy diy job on this handset.

3, The phone is blocked, i.e reported lost or stolen. Some networks when a phone is reported will allow it to get reception but will not let it make calls, however other networks will not give it reception at all and hence you get a Sim Card Registration failed message.

I hope this helps, these are the causes of the message.

Phone says sim card registration has failed

When the message sim card registration failed comes up it is usually as a result of one of 2 things the first being that the phone has not recognized the sim card due to an improper fixing or the sim card has become faulty. Simply try the sim on a different mobile device to determine if the sim card is still good.

SIM card registration failed

You might have filled up the memory to the brim and the phone doesn't have enough to switch on.
Try reformat to original settings. anything you stored on the phone will be lost.

How to reformat your phone, first turn it OFF. Press * 3 send at the same time and keep them pressed while you turn the phone on.
Give it time to work.

Remember, do not let go the 3 keys until you see the formatting screen.
After a few minutes when the process is over, your Nokia N70 will be back to the original delivered system.
