Next customers should check to ensure that the SIM card is properly installed. This process varies based on the model of phone. Customers should refer to the manual to learn how to locate the SIM card, which may be located on the side of the phone or under the battery. If the SIM card is properly installed, try the SIM card in another phone, if possible. If it still does not work, it may be a defective card.
