Yes this is very much true.....try to have it fully service then reflash the firmware if this does not give you back a signal then replaced the mainboard.

Iv just bought a blackberry 8900 and iv put a orange sim in and it seems to have signal but wont let me call out or give me my mobile number, can u help?

In this case you need to contact you're service provider for the network unlock code, Once they unlock your Handheld you will be able to use your Handheld with any service provider.

Lg kf700 wont accept any sim cards,


it sounds weird that it worked before with same sim card. Generally USIM locked message means phone is locked to network and you need to unlock it with network unlock code to remove USIM locked and use phone on different network.

Limited Service ???

what has happened is that the original owner has reported it to O2 and they have applied an IMEI bar to the handset that will be circulated to all uk networks. So unfortunately the phone is now useless! Dont bother spending money trying to unlock as you would be wasting your money once all the networks know. It probably worked for a while because the owner didnt report it straight away. Shame, not a bad phone!

lindipsy, it seems that the phone is asking you for your SIM's pin number. it should be written on it somewhere.
Usually 0000 or 1234 work, if there is no real SIM PIN number lock.
