If you're an iPhone user and the SIM card is locked, here are the steps to help you unlock it.
-
Contact the carrier. If you have another phone, try to make a call to the carrier's customer service. If your carrier has a website, also get in touch with customer support via the live chat on their website.
-
Get PUK Code to unlock. You should ask for the PUK code after getting in touch with customer service. The code is 8 digits and you'll have 10 attempts to input it.
By the way, if your iPhone shows "SIM not valid" or "SIM not supported, then try to deal with the problems a computer program called iMyFone iBypasser.

I just unlocked my phone. and put an optus sim in it to make sure it was unlocked. will the phone be locked to optus now?
No - the phone is the item unlocked - not the SIM card. If you were to replace the Optus SIM card with (for example) a T-mobile SIM - it would register to T-mobile. You could swap the SIM card back with the Optus card, and still use it.

No as they may be locked to a particular handset but if they are not you can move the SIM card to an other handset. Nokia do not have their own SIM cards they just lock the SIM card to their network via the SIM card settings.

It sounds like your phone is locked to a specific network (not the network for your SIM card). You might need to get it unlocked before you can use the SIM you have.

Can you change or spoof the IMEI of an unlocked GSM phone in order to use it with a SIM card that's locked to a different phone?
A SIM is not "locked to a phone" -- the phone is locked to use only SIMs for a specific network. In other words, any SIM will work in any unlocked phone. A locked phone will work with any SIM from the network it is locked to. Changing the IMEI (which is rumoured to be possible, but I am not sure) wouldn't make any difference -- if the phone is unlocked, you can already use any SIM in it.
How do you open block SIM card?
