If your mobile is unlocked means it will work with any other GSM sim card.First Check whether it is unlocked or not?
To check ,switch on your mobile phone with a sim card from a network other than the network you are currently with. If you are able to use the phone, you can be sure that your phone is not locked. If your phone displays an error message saying "Wrong sim" or "Incorrect sim" or "Emergency calls only", etc., then your phone is probably locked. If it is locked means you can unlock it with a good ,reliable and affordable unlocking service from an online vendor like UnBBlock.com .To get the service you need to submit your country name and IMEI number.
