No you can't, it makes you put in a password and it may damage your phone.
I had to unlock my phone and what you do is ring up your current provider and they will give you a code to put in to your phone which will unlock it from the provider and then you can use any sim card from any provider in the phone.
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.
Yes all you have to do is buy an unlocked Nokia c3 and put a Telstra simcard in it Its that simple :) !! I have one and it is better with optus boost because it is not ment to be with telstra Hope this helps !! :) Cookie Monster COOL THANX REALLY NEEDED THAT CAUSE I HAVE TELSTRA AND THATS THE ONLY THING YOU CAN GET IN MY HOUSE LOCATION AREA
As long as your phone is not SIM- or network-locked, then yes, you can switch carriers.If notyou have to get your phone unlocked from any vendors online like unbblock.com for blackberry phones and Simpleunlocking.com for other model phones
Just let your phone read your memory card and wait.
take out the sim and type in #*7337# put the sim back in and youre done
It all depends if the phone is sim locked. There are never any restrictions on sim cards only on the phones you can use them in. If you have a phone that you want to use was originally from Telstra either prepaid or from a previous contract it wont be a problem however if your phone was previously for example on a Optus contract your mobile MAY be sim locked. It is not always the case that the phone is sim locked (sim locked means you can only put a sim card from the same company that originally supplied the phone) When purchasing a phone the best thing would be to check with your local Telstra or all phones dealer if the phone you are buying is sim locked to a particular phone company.
The sim card.
Yes you can take the sd card out of the phone
it can or can not be it depends on your phone IT depends if you saved it to the sim card or the phone because you can do both
can you put a virgin simcard into a orange phone
Put the SIM card from the new phone into the old one. Copy the contacts from the old phone's memory to the SIM card. Put the SIM car back in the new phone - then - either copy the contacts to the new phone's memory - or leave them on the SIM card. Either way - the new phone will find them.
