So even if you receive the 'Awesome' message on our device checker, you still need to check if the phone is unlocked or not.Ĭontact the existing carrier to confirm the locked status of the device or if you are buying a new phone, confirm with the seller. Our device checker can check for compatibility only - you must check that the phone is unlocked. Unlocked and Compatible are 2 completely different unrelated requirements. Whether you device is compatible or not, the phone needs to be unlocked. Phones made for overseas markets and older phones are more likely not to accommodate these band requirements. However, for best service on our GSM network, your phone should have at least 1 of the following bands/frequencies in addition to the above 3:įor example, if the phone has bands 2, 4, 12, and 71, then that is ideal.
