Solution
Q&A

SIM (Subscriber Identity Module) cards are currently used in all GSM-based systems. The SIM card is a removable module that contains user identity, account information, and stores phone numbers which can be used in any compatible phone where your SIM card is present. When inserted into a telephone, it allows you to place or receive calls. The SIM card may already be inserted into your phone when you receive it from the dealer. If it is not, you can easily insert it into the slot provided on the handset.
