hi all i have a prepaid simcard in which the number of units or minutes i can calL and speak appear in the mobile screen,for example a if i put new card from company a numer 180 appears on my nokia phone screen and then each time i speak this number start to decrease untill it reach to 0 then i cannot make calls

MY QUASTION IS ABOUT RECHARGING PROCESS: I SIMPLY BUY A CARD WITH A 12DIGIT NUMBER , I CAL A COMPANY NUMBER AND ENTER 12 DIGIT NUMER AND THEN I WAIT FOR LESS THAN 1MIN AND I RECIVE AN SMS FROM COMPANY NUMBER TILLING ME THAT MY CARD IS RECHARGED WITH A 180 UNIT,AND THE NEW UNIT NUMBER DOESNT APPEAR ON THE SCREEN ONLY WHEN I RESTART MY PHONE(THATS MEAN THE NUMBER OF UNITS IS STORED IN THE SIM AND EACH TIME I TALK A COUNTER IN THE SIM WILL DECREASE MY UNIT SO THIS MEAN THAT THE SIM IS DIFFERENT FROM OTHER SIMCARD WHERE THE UNIT CREDIT STORED IN THE COMPANY COMPUTR),NOWWWW,
THE SMS I RECIVED IS A BLINK MESSEGE AND BY SOME WAY IT ADD THE NUMBER OF UNITS ON MY PHONE(ONLY WHEN I RESTART MY PHONE) ,
IF I CLONED MY SIM THEN I CAN ADJUST THE VLAUE OF ACM(ACCUMALTED CALL METER) AND ITS IS IT POSSIBLE TO MAKE FREE CALLS
IN MY OPINION I THINK THAT IN THIS TYPE OF SIMCARD BCZ THE NUMBER OF UNITS ARE STORED IN THE SIMCARD CHIP AND ITS RELATED TO ACM !!ANY SUJJESSTION OR IDEAS I WILL BE GRATFULL THANXXXXXX:eek: :confused:

Hi !
These are special prepaid-cards with PIN2/PUK2 factory-blocked.
You cannot make free calls even with a cloned card. The counter is stored in the gsm-center too. When it reach 0, the call will be cut off.
The cloned card cannot decode any upgrade-SMS from the gsm-center and you have to adjust the counter manually each time you recharge the card. Because that, it is not so easy to use such cloned cards.
Please excuse my english...

Hi !
you should check if the PIN2/PUK2 are blocked.
Simply select in the phone menus PIN2 change. If the phone says 'PIN2 rejected' then it is blocked. When PUK2 is not requested, it is also blocked.
With the lost units, I can say that such SMS can be requested from the GSM center with special USSD codes. The operator typed the right USSD code in your phone and the GSM center sent a upgrade SMS to your card that automatically upgraded the counters.
You cannot view such SMS. They are not stored on the card but processed instantly and replaced with the appropiated text, for example 'please restart the phone' or something else.
