Description : Can i switch my sim card that is telstra which is in my iphone and put a optus sim card in my iphone?
Last Answer : Simply said: can you use another sim in your iPhone? If you've bought your iPhone with a carrier, why not stick to it? The answer to your question is: yes, you can, but it is illegal. You have to jailbreak ... . If you've bought your iPhone w/o a contract, you can put in an other SIM like that. :)
