Yes, you can as long as the O2 phone is unlocked, then you can use a Vodafone SIM on it, or a SIM card from a different carrier.
Yes, An "Unlocked" Phone means you can put ANY operator ("Orange", "Vodafone" etc) SIM card in it.
If both the SIM you want to use and the phone you want to use it on are unlocked, then this is possible.
If the Motorola you have is unlocked to work on any network then yes it will, if it is not unlocked, then you will need to get in contact with the original network provider and ask them to unlock it
NO it isnt the same kind of phone to do that.
I have unlocked my motorola v173 through unlock code. I got unlock code from this site OnlineGsmUnlock.com and unlocked my motorola v173. Then i am Now able to use any sim card for motorola v173 mobile
where is the sim card location in a motorola w315 wireless phone?
Have you allready tried another network's sim card in the phone because I bought mine on Vodafone from Phones4U and it was already "Unlocked"
the sim card from your Motorola rizr can be transfered to any phone that is a phone that your network provides. (i.e. a sprint sim card cannot work in an at&t phone)
no
No reason why not - the old SIM card should still work.
Yes.
