Default Network Blocked - Invalid SIM Card problem

Please Login to Remove!

I need help!

Here are the symptoms:

1. My SIM card shows the following:

Network---------- Blocked
Network Subnet---Disabled
Service Provider---Disabled

2. When I restart my phone, I get the following message:

Your current SIM card requires an unlock code. Would you like to unlock it?
However, when I say yes (or NO for that matter) the window disappears without giving me the opportunity to enter anything.

3. The main screen always displays: Invalid SIM Card

4. I am unable to use the phone overseas. The same phone used to work overseas. This is a new problem.

5. The phone works fine in the US.

6. Verizon could not help. They offered to exchange the phone, which I am trying to avoid, since I have a lot of customized setting that I don't want to redo.

Here's what I have done with no success:

1. Got a new SIM card from Verizon.
2. Tried every combination possible of MEP2, MEPP2, with a SIM, without a SIM, with a new Verizon SIM, all without success. The window requesting the unlock code never came up.
3. Did a reset to factory setting and a total wipe out, and repeated the above.

Any ideas?

Thank you very much

sounds like you entered the unlock codes too many times and now the phone is locked to the original carrier service.

There is no coming back from entering the wrong unlock code too many times.

If it's blocked because the unlock code was entered too many times, find a shop that offers DM3 unlocking. They will need to physically access the device via the USB port. You cannot do it yourself.
