Nokia 7373

Some phones are past their sell by date. They then bow out and die. Yours may have belong to you for a few years, in which case it probably has (died). Or the phone may have been found, and the SIM lock is blocking the phone. Or the phone security pin number may have blocked the phone. Or there may be a component not working any more on the phone. The Nokia 7373 is a few years old now and it really is looking to retire gracefully. Go back to the original question, and the answer is the first one I gave you.

The impossible I can do straight away, miracles take a little longer.

Sim lock

Complete information :
The SIM card protects your subscription and not the phone from unauthorised users. If you change SIM cards you can still use your phone with a new SIM card. Most SIM cards are blocked at the time of purchase. If your SIM card lock is on you have to enter your PIN (Personal Identity Card) every time you turn on the phone.

If you enter the wrong password three times in a row the SIM card gets blocked. This is indicated by the message PIN Blocked To unblock this you need to enter your PUK


card (Personal Unblocking Key). Your PIN and PUK is supplied by your service provider. You can edit your PIN and select a new four to eight digit number
  • If the Message Codes do not match appears when you edit your PIN you entered the new PIN incorrectly.
  • If the message Wrong PIN followed by Old PIN appears then it means that you have entered the old PIN incorrectly.

To unblock your SIM card:
  1. When PIN Blocked appears enter your PUK > OK
  2. Enter a new four to eight PIN > OK
  3. Re-enter the new PIN to confirm > OK

To edit your PIN:
  1. > Settings > the General tab > Security > Locks > SIM Protection > Change PIN
  2. Enter your PIN > OK
  3. Enter a new four to eight digit PIN to confirm > OK

To turn the SIM card On /Off
  1. > Settings > the General tab > Security > Locks > SIM Protection > Protection and select On or Off
  2. Enter your PIN > OK
