How SIM Cards Actually Work

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.

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.

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

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.

I was 23 years when I got my first sim card in 2001. I love when phones got a sims card because can keep the same number when the phone breaks.

I was 47 when I got my first cell phone. A mere nine years ago.

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.

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.
