I got my very first phone at about the age of 18… Yea I know, I had to wait that long. Kids of today won’t understand the struggle and how privileged one was to own a mobile phone back in the days.
I remember my first phone was a Motorola… I’ve forgotten the exact brand but it was black and shaped almost like an egg. The length was roughly 5 to 6 centimetres and width of about 2.5 centimetres.
I remember there was a time when I curiously thought to dial my own number on my first mobile phone but unfortunately, nothing happened… the line just dropped.
As I grew older dual SIM phones came into fashion, and in fact they are the in thing now. My first dual SIM phone was a Chinese one, I think it was called GShock or Gtech or something like that LOL! I don’t know why it never occurred to me to try using one of the SIM cards to call the other then.
Anyways, I eventually got to try calling my other number on a dual SIM phone when I got my Samsung Note 8 about 3 years or so ago. I tried to call one SIM from the other but every single time I tried, I got a reply along the lines of “sorry, the customer is not reachable”.
I am sure I am not alone in this quandary or state of morbid curiosity. I am sure many people have tried this at least once.
This then brings me to the place where I begin to explain to you why you were unable to either call yourself on your single SIM phone or call your other number on your Dual SIM phone device.
The Simple Explanation
When you attempt to call yourself, your number becomes busy trying to send out a call.
What happens next?
Your number can’t receive that call because at that moment it is busy trying to execute another call!
Here’s my layman technical explanation for this 🙂 (not layman layman, at least I did a bit of reading to get some understanding which I am now sharing)
Under normal circumstances, when you try to call another person, a signal is sent to the satellite, the satellite then receives this signal and sends it to the person who are trying to call. However, in the case where you trying to call yourself, your phone is busy sending out a signal and cannot receive another signal at the same time.
It doesn’t end here.
Programming from network operators could be also responsible. When you call a busy line (not your phone number), the system activates call waiting.
However, in the case of calling your own phone number, the system does not allow call waiting.
I hope I have been able to proffer some sound explanation, basic as it may seem 🙂
