How about the safety of my identity?

According to NBTC: “Rest assured that it is absolutely safe because the 2 Shots NBTC-developed application does not store any photos on smartphone; instead, it submits data directly to both NBTC and mobile phone network operators. Those who can get access to this application must be distributors who have been certified by mobile phone network operators only. To make the access safer, distributors need to have username and password in order to access the application.”


What if I can not register the SIM card by myself?

According to NBTC: “Customers can authorize other people to do the registration for themselves at every branch of at Telecom center.  Documents and evidences needed for registration include the following:

1) Power of Attorney

2) ID card or other identified official cards of the number owner

3) ID card of attorney and

4) Mobile phone and SIM card of the number owner.”


What if I do not register?

This is not yet been confirmed, but NBTC has the right to cancel your number.
