i disagree ur first point up there that when u dail a number a signal is sent to satellite(earth station) then return to the subscriber(phone user or ground station) base on these two reasons

1.we have a device called transceiver meaning a transmitter and a receiver in telecoms engineering,this device allow information signal to be transmitted and received at thesame time as a result future tech could embed this device to serve the purpose.

2. We have a term called multiplexing in telecom which allow many information signals to transmitted over thesame channel simultaneously,future tech could also include this on smart phone device........back to the main discussion,the major reason why you can not call your own number is that,at a particular time u are dailing ur own sim card number from ur phone your SIM card is already in busy hour which may result from call congestion or any other factors like time,now what do i mean by busy hour? Busy hour is a term that denote the time or period during which a telephone subscriber is offering a call......from this explanation i have made tell me how u would be making call from ur own phone number through ur device and still be receiving ur own call,i stop here.i am an electrical engineering student telecom option(undergraduate).....there is room for correction if any.

OP.. use airtel, put ** before your number there you go.. You hitched your send receive satellite theory.. But if you need advanced hitch.. DM me. I'll give you the rebound codes. Turn your phone to a talkie talkie!

You must be trying to be mad for trying and attempting to call yourself!!!! What do you want to say to yourself when you call yourself!

onward4life:


Now hold it right there !!!!

All Yu said is true even by merely reading ur first letter word and looking at the comments!

But

Ok I noticed when I was attempting to call my line...

Yu sometimes get a missed call notification to inform Yu day so so person attempted to reach Yu.

But it never happened when I tried calling my line...

Could Yu throw more light on that please!!!

Thanks in anticipation!!!

The reason why you can't call your own phone Is because it's stupid!!!!!

Great explanation, but I just want to add my little telecom experience.

The word satellite used in the article was big, truly there are phones, like Thuraya that could make call through the Satellite but our daily day-to-day phones services (mtn,glo,etisalat) are connecting through cell towers (radios) which we popularly called mast in Nigeria. Mast is just the name of the pole that carries the cell tower. Those of us that grew in the 90s know Satellite phone is for the big boys. Thank God for radio phones that breaks the barrier.

Your phone does not create/send a new signal when you attempt a call. Your phone is always transmitting signals (power), and the cell towers are continuously transmitting signals (power) too. As you are going around, there are information that your phone keeps sending to cell towers, and there are information that your cell towers keep sending to your phone. They always have to transmit signals because calls may want to come in at any time. That's why operators can make your phone battery last more or burn faster. They can set up sleeping time for your phone not to communicate at all. It will be in milliseconds so it won't have a significant impact on incoming calls, but sometimes if incoming calls jam the time your phone is sleeping, which rarely happen, you won't see the call, but it will be ringing at the other end.

I agree with your point that not be able to call yourself is more of an operator setting than the technology. Most operators can change the settings to whatever they like. In Nigeria, it will tell you busy, in some advanced countries, you will be sent to your voicemail box when you try to call yourself. Most GSM uses FDD, and in FDD, both uploading (talking) and downloading (receiving) can go pari pasu cos you created a different path (frequency allocation) for them.

When I was younger and got my first phone from my parents, I tried sometimes to call my number from my phone but it never went through for once.

As I grew older and owned a dual SIM phone, 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 believe you have tried it once (well, that's if you're inquisitive as me). So, let's get to the point of this article- why you can't call your number from your phone.

Here's a really 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 it's busy trying to make a call happen!

Here's a bit technical explanation. When you attempt a call, a signal is sent to the satellite, the satellite receives it and sends it to the person who are trying to call. In the case where you're trying to call yourself, your phone is busy sending out a signal and cannot receive another at the same time.

But this is not where it ends.

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(invoke) call waiting.

So now you know why the call never went through.
