Thus, a way to recharge SIM cards without such limitations is required.
The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of device and method for recharging SIM card. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The user sequentially inputs recharging information to the mobile phone 100 via a recharging interface provided by the display 30 (S103), wherein the recharging information containing a phone number associated with the second SIM card and charging amount for the first SIM card.
In a first embodiment of the present disclosure, the first SIM card is installed on the mobile phone 100, and the identifying information is a personal identification number (PIN) associated with the second SIM card. After the step S105, as the first and the second short messages have been sent to the operator 200, the operator 200 determines if the phone number in the recharging information matches with the PIN, and transfers the charging amount from the balance in the second SIM card to the first SIM card if the phone number matches the PIN.
In a second embodiment of the present disclosure, it is the second SIM card being installed on the mobile phone 100, and the identifying information is the phone number associated with the first SIM card. After the step S105, the operator 200 determines if the phone number in the recharging information matches with a phone number sending the first short message and the second short message. If yes, the operator 200 transfers the charging amount from the balance in the second SIM card to the first SIM card.
