Calls from Vietnam

I don't get it...

A while back I would regularly receive phone calls from Vietnam... always from the same number.

First I wasn't sure where the call was coming from since I'm not used to seeing a phone number that looks like "+123456789123." I knew that since it had 12 digits it was more than likely an international call. But that's not the only reason I didn't answer it.

First off, I'm not sure how international calls work. I don't know if they're like text messages... meaning I'm not sure if I'll be charged for the call even though I didn't make it much like those without a text messaging plan will be charged for received text messages. Second off, I rarely ever answer my phone when it's from a number I don't recognize.

The odd thing about this was that they were leaving voice mail messages. None of the messages were understandable to me. They all sounded like my number had been dialed by accident in a purse or a pocket. The voice was mumbled and there was a little bit of static.

After the first message I figured that it was a random, accidental call. However, this person kept calling back... and kept leaving messages... and the later messages weren't muffled nor did they contain any static. The lady sounded to be a little grandma lady or something... so then I figured she must not get many calls and must have accidentally hit the redial button.

But then, several weeks after that, I received another call from this person. I figured by this point that this wasn't an accident... but I was (and still am) completely baffled as to why this person continues to call me. My voicemail message is in English... this woman apparently does not speak a word of English but decides that I must be the person she's trying to contact and leaves messages anyways.

I think so far I've received at least 10 - 15 calls from this person.

Well...

It has been several months (maybe almost a year now) since I have heard from my Vietnamese Idiot. But tonight during my class my phone rang. I looked down and noticed that I was receiving an international call. But I was glad when I felt the vibration inform me that I had a voicemail message.

Since it has been so long since I have received an international call I had completely forgotten about this whole ordeal. So when I got back to my apartment I decided I'd try to figure out where this call was coming from.

I did a basic search of international calling codes and realized that this was a call from Vietnam. I'm not 100% sure that it's the same number as before, but what are the odds of two people in Vietnam randomly calling my number?

This time I went a bit further in my research and found that this call is coming from Hanoi. Not a huge help to me, but, whatever.

With all that being said, the phone number I receive is +841698534579

I'm not exactly sure how one would call this number (since I've never actually made an international call) but if what I've read online is correct the number that would need to be dialed (from the states) is: 011 84 98534579

If that is correct, I'm not sure what the "16" is for in the number I have. I know 84 is the country code... and Hanoi has 8 digit phone numbers (which I read were the last 8 digits)... but I am having a hard time figuring out what the 2 digits after the country code are for.

Anyways, if you want to, please feel free to call this person regularly and leave them long, pointless messages that you are sure they will not be able to understand. (i.e. leave the message in Pig Latin or Gibberish)
