BSNL cutting regular SIMs to Micro SIMs for customers

[GarfieldDC]

The fact is that technology evolves over a period of time. He trend has been that devices get smaller and smaller in size. A long time ago the SIM card was the size of a credit card. It was actually the whole card that we now get when we buy a SIM. But now we pop out the smaller cut out of the SIM and use that. I had a Motorola phone a long time ago which actually accepted the whole credit card size SIM. What we now accept to be the normal SIM is actually a "Mini SIM" Then came the next logical evolution - the Micro SIM. Through out the evolution of the SIM card, the size of the actual chip has pretty much remained the same. It is only the surrounding plastic that has been trimmed to make it sleeker. The Micro SIM is here to stay until the next evolutionary jump. There are already rumors that Apple is experimenting with a SIM-less iPhone design.

The question is if OLD SIM works just by cutting it, then why didnt they start in small size itself? Why did they add unnecessary surrounding plastic?Abt sim-less phone, we already have SIM less phones.. OLD reliance mobiles were simless phones (the one, the price of which dropped from 10000Rs to 500Rs in a year!)

Why didn't they start small? It's like asking why didn't they start by making handheld computers instead of making a computer that was as big as an average room. It was in like with the handset technology of the time..devices were larger, people were not obsessed with smaller sized devices. They had room to fit the big card in. Earlier handset manufacturers designed their handsets around existing technologies and component designs. Someone invented a huge SIM card and handset they designed their device to accept it. Now on the other hand, most of the time, it is the device manufacturers who dictate the design of components that fit into their devices.

That's how any technology or service evolves. Someone invents or discovers something and it is accepted by everyone. Then someone comes along and looks at it differently and figures out a way to do it differently, which is more in line with current needs/times. At this stage the old version which was the norm gets rejected and the new one becomes the norm and so on.

The SiM-less phones you are referring to (Reliance) are CDMA phones. That technology is different and does not require a SIM. The Verizon iPhone for example follows this and does not require a SIM card. What I was referring to in my earlier post was SIM-less GSM phones.

Sim less phones seem pretty logical. Buy the connection, the operator would send some sort of authorization code to your phone and that's it. I guess this would happen in the future.

Apple had planned this for iPhone 5. But carriers were not in favor of it. They did not want to lose the last connection they had with customers. (based on rumors online!)

That's because mini SIM's are easier to hold and handle than micro SIM's.

Just saw one of those SIM cutters being sold for 180 odd bucks on ebay along with a free adapter.
