Advantage 2= STK / USSD Mobile recharge

Function= Top Up / Mobile Recharge + Check Balances

STK consists of a set of commands programmed into the SIM which define how the SIM should interact directly with the outside world and initiates commands independently of the handset and the network. This enables the SIM to build up an interactive exchange between a network application and the end user and access, or control access to, the network. The SIM also gives commands to the handset such as displaying menus and/or asking for user input.

 

USSD is commonly used by prepaid GSM cellular phones to query the available balance. The vendor's "check balance" application hides the details of the USSD protocol from the user. On some pay as you go networks, such as Tesco Mobile, once a user performs an action that costs money, the user sees a USSD message with his or her new balance. USSD can also be used to refill the balance on the user's SIM card and to deliver one time passwords or PIN codes.

 

Advantage 3= Change IMEI

 

What is "IMEI"? 

 

"IMEI "is a abbriviation  for "International Mobile Equipment Identity ",International Mobile Equipment identification number is by the 15 of digits "electronic string of number",and this code is the world's only. Each a mobile phone in after the completion of the assembly will be given a global only a group of number, the number from production to delivery will be took record.

 

Why need to change "IMEI" ?

 

 When you use the modem pool for SMS too much ,due to the operator policies,your device will be blocked  .World of operators will be same condition ,So if u want a SMS competition business,IMEI changing function is very needed
