It is the phone itself. SIM cards are peculiar to GSM phones. There are other types that do not use a SIM card. The SIM card carries information that is specific to the subscriber. All phones have operating software. Some of the software is common to all phones, regardless of who the carrier is. Some portions of the programming are reserved for the carrier. An example of this would be the banner the user sees when the phone is powering up, but there is a lot of programming that is transparent to the user, which is protected by the lock.

Try a sim card from a different carrier. If the phone works with the new sim card, then it's unlocked.

Yes you can! as long as the phone is unlocked any sim card will work in it :)

If the phone is unlocked you should be able to put any type of sim card in there as long as it is a GSM phone with a sim card slot.

If the phone is unlocked you can use a sim card from any service provider, as long as the phone is built to take sim cards.

You can put any SIM card in an unlocked cell phone.

Yes it is possible to see if your phone is unlocked. You can borrow a sim card from someone who has a cellphone with a different service company. If the card works and the phone thinks its your friends phone then your phone is unlocked.

Yes you can. If the handset s unlocked, it will accept any carrier's SIM card.

There should be no problem if you use a SIM card in an unlocked phone. If the phone is locked make sure the network is available to you.

An unlocked phone can accept the SIM card from any cell phone provider. If you have an ATT SIM card, you can use it in an unlocked phone. A locked phone is created by the provider to force the use of its service; an unlocked phone can take any SIM card.

If both the SIM you want to use and the phone you want to use it on are unlocked, then this is possible.

Any cell phone that is unlocked requires a SIM card to work. If you own a Sidekick cell phone that is unlocked you are able to use a carrier other than T-Mobile. For this reason, it will require a SIM card to work.

For a cell phone to be unlocked, it means that the phone is able to use any SIM card from any phone network type. For example, a locked Verizon Wireless phone would be unable to accept and function with an AT&T SIM card, whilst an unlocked Verizon Wireless phone would be able to accept and function with an AT&T SIM card.

Yes, An "Unlocked" Phone means you can put ANY operator ("Orange", "Vodafone" etc) SIM card in it.

yes if your phone is unlocked from china or hong kong or an american att or tmobil services...(Unlocked)

Only if the SIM card has been unlocked first.

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 if your Razr is from Cingular or unlocked. You can not use a T-Mobile Razor with Cingular prepaid sim card or Globaltravellersim prepaid international sim card unless your phone is unlocked.
