HOW CAN AND HOW MUCH SIM I CAN REGISTERED FROM THE SAME NATIONAL ID CARD?
Biometric registration of SIM cards for mobile phones, has started trial runs. Go to the biometric registration as soon as possible.
Warning: Someone told me that it might be a scam, such as when I tried to confirm it with the GP, they said, they do not know about the registration SMS. So be careful !. Although the company online registration valid program.
All existing SIM card all the way to the operator to re-register as a link to the official notice of termination to avoid trying to enter. While you are there as a preferred means of SMS Customer Care Centre will be a lot more chaos, either SMS or online can do it.
