It just means that your phone is not "open line" or it cannot be used for all networks. you have to ask a service center for your phone to be "open line" or to open line it. Once it's open line, you can use durrga or watanya sim.

Need unlock code for sony ericsson z550a for a tmobile SIM


Hi, If you get error message as PIN blocked. Unlock?" You have entered the wrong PIN code too many times. You need to unlock your phone using the PUK (PIN Unlocking Key) code. Your PUK code is provided by your network operator. If you get error message as Insert correct SIM" You have inserted a SIM card that is not supported. Insert correct SIM card, or contact your Service Provider for a SIM unlock code. If you get error message as Phone locked" or "Enter PIN" Your phone is locked and you need to unlock it with your personal PIN. The default PIN is '0000', but you or your network operator may have changed it. I Hope it helped you. Thank you for using ' Fixya ' and have a nice day!!

Vodafone sim problem.


i think the sim validity period has been expired ...
i mean if you didnt recharge for 90 days the sim validity will be getting expired automatically... this is made by the network operator in standard for all sim cards ....
if it is not true then try inserting in other handset & have a try ...
if you face same problem then really the sim validity has been expired ...
take a new sim....

Insert correct sim card


Un-Clocked is temporary, allows free txt and calls for a few minutes.
Un-Locked from a network is what will allow you to use any sim card on your phone.
