I disagree, the ICCID info seems off for linking to a user.

Wait, is the Viber account really just that number? Sounds odd.

I think the account can be tied to the IMSI, not just the message.

I thought the user account would be tied to the phone number, not just a string of numbers, so I'm a bit confused about option C.

I practiced a question similar to this, and I feel like the IMSI and ICCID are important, but I’m not confident about which one applies here.

I think option B sounds familiar because it relates to how SIM cards and user accounts can be connected, but I can't recall the exact details.

I remember we discussed how Viber messages are stored, but I'm not sure if we can directly link a message to a specific string like that.

Haha, this question is a real head-scratcher! I'm going to go with C just to see what happens. Who knows, maybe the Viber account is actually the IMSI number itself!

I think D is the right answer. The ICCID, which is the unique identifier for the SIM card, should be the one that can be linked to the Viber account.
