No magic behind it. It uses processors embedded in tiny circuits just as what you find on electronic devices . 1 Like |

Nothing much than using of jinn in the waive to deliver ur calls and receive. Just like how prophet sulaimon do send jinn to deliver and receive messages for him . Very simple and clear. |

HugeElephant: SimCard is just part of the group of integrated circuits that carries out the operations you mentioned. The MicroWave which is an electromagnetic devices transmit most of the informations across the SimCards. The funny thing is you will be marveled when you get to know that SimCard is just a tiny fraction and the least of what makes up Telecommunications. It's not a straightforward process as you taught.

Tear the gold copper of the sim you will find a tiny circuit inside.The base station mast is connected between your SIM card. That is why you cannot be able to make and receive call when the base station is not available close to your area. |

so many things to pounder about, what the brain can do is limitless i bet something to stop aging will be developed soon if the world doesnt implode. |

Here is my question. How does e-sim work ? since no hardware or physical sim is involved. If e-sim is possible , then we shouldn't need normal sim again |

Your simcard is just a card with unique coded information. It cannot send and receive data on its own. The coded message is only there to be read by a mobile equipment. Now, every network service provider has a database containing several accounts. Each of this accounts matches with the coded message on each SIM card. These message on the SIM card is unique and identifies each subscriber. It is the mobile communication devices like phones, tablets, modems etc that sends and receives data. They read the unique information on the SIM card, sends it to the service provider database. The Service provider matches the info to an account and gives you access to their services. The same way the ATM and some finger print services operate. |

The power of voltage modulations aka ones and zeros aka binaries. There's a lot of physics, mathematics and engineering under the hood of the abstraction that is a SIM card or any other chip. It's super interesting what you'll learn, if you're curious enough to dig deeper |

HugeElephant: Alright! Imagine a SIM card like a tiny, special brain for your phone. It's a small chip that has all the important information your phone needs to connect to the mobile network. Inside this chip, there are tiny electronic parts that store things like your phone number and a secret code that helps keep your phone conversations and messages safe. When you put the SIM card into your phone, it's like giving your phone its own special ID card so it can talk to the network and do things like make calls, send texts, and use the internet. Hope you understand now☺️ |
