What SIM does stand for? It means subscriber identity module or subscriber identification module. The first SIM card in the world was developed in 1991 by the German company Giesecke & Devrient. They sold 300 SIM cards to Radiolinja, a Finnish wireless network operator. In 1992, they sold the first GSM mobile phone with a SIM card; it was a Nokia 1101. Today, it’s hard to find a person who’s never used a SIM card - over 7 billion gadgets around the world use them to make calls, send SMS and surf the web.

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.

@markseddon3292 5 лет назад

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!

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.

@ryangordon5986 4 года назад

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.

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

On some networks, a GSM phone without a SIM card may be used to make emergency calls, and most GSM phones accept a larger list of emergency numbers without SIM card, such as 112, 911, 118, 119, 000, 110, 08, and 999

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.
