    Will the SIM card work with my mobile phone?

The service is compatible with most late model multi-band GSM mobile phones. *
However, you must first ensure that your mobile phone is unlocked. The easiest way to do this is to insert a SIM card from a different network into your phone. For example, if you have a T-Mobile SIM card, try inserting your friend’s Regular SIM card. If your phone operates normally, it is unlocked. However, if you receive a strange message on your screen, your phone is locked and you will need to contact your mobile operator and request an “unlock code”, which they are obliged to give you, although certain conditions may apply. For more detailed directions on how to unlock your phone, .
