How SIM Cards Actually Work

[@BRIGHTSIDEOFFICIAL]

Hey there, BrightSiders! Do you have a regular or a micro SIM card?

[@farisspicypeanut]

BRIGHT SIDE OMg you replied and hearted it thx soo much I love your videos also I am going there by plane

[@boburdz2020]

Nano sim. 🙂

[@diorynovis]

Regular

[@ghitaciprian]

Nano SIM

[@manikdeepak1111]

Micro coz my phone doesn't supports regular

[@ThusIsBrad]

In 9 minutes and twenty seconds a video titled "how do SIM cards actually work" fails to describe how SIM cards actually work.

[@Zikeal-d4l]

Huh?

[@Bryanbkk]

Yeah, they missed the call encryption handshake with the carrier part.

[@thedutchone2442]

Indeed , the exact purpose of it , by going in to the smaller pieces. The best faillure is actualy saying there is no satelite connected to your simcard.....just towers....now i know why i cannot make phonecalls in a forrest, or mountainrange.

[@happyfeet7280]

Yup

[@robertmeigs5176]

My first thought as well. What's in it does not tell how it works! Also, it's NOT made of "silicone"! This guy is ignorant!

[@boburdz2020]

Out of all the things to talk about, you picked simcard?? What a brilliant idea dude!!! Nobody talks about its history and origin so much. Liked!!! 🙂🙂🙂

Fascinating video. I got my first mobile in 1995. I was 28. The phone was huge and very basic. No texts. Just calls. We’ve come a long way.

[@beerholikweissman8801]

Same SIM number i'm using since 2002. Had it replaced with the same number last year 2018 when the phone was stolen. 32K sim got a fresh upgrade. This vid is informative.

There’s a mistake in this video. Not all all carriers used SIM cards back then. Verizon Wireless, Sprint, and Nextel didn’t use them before. They used a different technology.

[@mrrich7368]

Oddly an important piece of information not disclosed, when the SIM is physically ejected from your phone, it can still in fact make emergency calls. This is particularly helpful as it does not matter if you have a SIM in your phone, or what network you're nearby. As long as the data bands on your phone match the bands produced from a serving site, you can call emergency services for help.

[@V3ryan]

I once gave my old phone to a kid to use so he can play games on it. It had no SIM card, so no way of making or receiving phone calls. His dad told me later on they found out the hard way that some phones can still make 911 calls without a SIM card. Useful tip to know.

[@tutacat]

All phones can call emergency services. It's the law. You have to teach it.

[@DoNotHireForever]

I’m fascinated by the E-Sim concept. I’ll be studying this...

My first mobile phone was a Motorola m301. Built like a brick with a credit card SIM. I remember when I upgraded in 1997 I had to go to a phone shop where they cut round the contact to make it a thumbnail SIM. I've still got the Motorola somewhere in our house... It will need to go to a museum soon!

Bright side the type of KZbin channel to tell me how sim card works

[@ryangordon5986]

A phone with no SIM card should still allow you to connect to emergency services when dialing 911, 999, etc... (also why smartphones have shortcuts for emergency numbers that bypass the lock screen) I believe the SIM card exists only to unscramble or unblock access to the network; a means of control for your service provider. Emergency services should be excluded from this. I was hoping the video would have been more clear about this.

Yes your Phone can, work without a sim card and, make local and international calls to land lines and mobile phones without a sim card..... All you need is access to internet, and an account with a social network that provides telecommunication like Skype or Google Hangouts and yes you can make local and International Phone calls.

[@immikhan781]

Planet Home are you mad ?

[@Yosetime]

I was 37 years old when I got my first flip phone. Texting was weird. And too difficult to bother with. I was 43 when I got my first iphone (yeah, slow, but technology doesn't interest me one bit). IPhone was too fussy so I now use Samsung. And still don't know much about SIM Cards. Except that when my phone screen broke my friend gave me his old one to use for awhile. It is called a Sky Pro 3. It has 2 SIM card ports and an SD card port!! So I can have 2 separate phone numbers on one phone, or use one SIM for calling and texting and one for data, and you have full control in settings. Super cool!! Add that I can also add another number through Voip like Google Voice or Talkatone, my one cheap backup phone with only 16 g of memory (which doesn't matter since I can use my SD card for memory as well as sync photos or back up photos to google, I have everything I need! This old gal figured all this out on my own. Took forever but I did it.

I liked the video but pls correct following - 2:03 -- Please never show IMSI with '+' sign. It's not MSISDN. 2:12 --- Those were the old times when SIM cards supported max. 64kb writable data. Nowadays, most of the companies provide SIM cards with 128kb memory. Few rolled out 256kb as well.

[@ramankhowal]

@@lunapriya2723 SIM cloning is generally not possible with Indian mobile operators. You'd need to study Comp128 security algorithm to understand it. There are many websites which allow people to send SMS from any number. eg., 160by2 was one of them.

[@tutacat]

eSIM and iSIM uses the same connection method. It is just rewritable and stored on the motherboard or SoC. It is different techonology, but it isn't inherently better at connecting or more secure. Though, it is physically harder to damage, or sim-swap. And preventing sim-swap could use ephemeral sims so if it is extracted it would be replaced quickly
