Why does the iPhone use a Nano SIM?

Piseth Mao March 6, 2013

What is the benefit of Nano SIM? Why does Apple use it for their new iPhone forcing users to cut their SIMs which sometimes destroy the SIM itself through the cutting process? It’s also hard for them to switch to another phone with that cut SIM.

    Obviously, we all know Apple is evil and doesn't want to make it easy for you to switch to Samsung in any way. To prove this, just look how Samsung had to adapt this technology into the Samsung Galaxy S3 in order to bring some of iPhone users.

    As other responders have explained the reasons for Apple using Nano SIM,I would like to say that you can use SIM card adapters like Nano to Micro SIM or Normal SIM adapters to use that SIM in other phones.

    simple awnser: because it is smaller! apple wanted to get more usable space by getting rid of the one used by the other sim card type

    Love this great explanation!

    Additionally, Apple is betting that Nano SIM is where the current market is heading. They're looking to get their phones thinner and thinner, which will mean components needing to work with flatter space, while still delivering where people expect it from them. Each iPhone is expected to be faster, long battery life, sturdy but light, sleek with high design, and basic hardware advances. So basically, the reason Nano SIMs are in the iPhones are the same reasons why any of the other components are: they work towards Apple's intent and goals.

    Nano SIM can liberate some space so that the phone can get larger battery:) you can also use sim adapters toh ost nanosim if you have older phones.

    For the most part, the design of the Nano SIM is so that other components could become larger while the overall size and shape of the phone becomes smaller/thinner/lighter. Though it is an inconvenience to cut the nano SIM and it may even lead to breaking of the SIM card if it isn't done properly, you could take the SIM to your local phone service provider's store and they should be able to professionally cut it without breaking it. Most of the time, they'll do it at no charge to you as well.

    You said it yourself - "It’s also hard for them to switch to another phone with that cut SIM."

    Ask yourself, why would Apple want to make it easy for you to switch back to Android etc.?

    technology moving toward vlsi and ulsi. in nano sim the circuit is reduced.
    by reducing circuit it will consume less power of battery and battery will give better response

      The SIM circuit doesn't change, actually you can just cut the standard SIM and use it but that's dangerous.

    The reason is as simple as the SIM being one of the biggest components within the phone. Technology is getting smaller wherein the power usage continuously increases. Therefor manufacturers try to make the technical components as small as possible to maximize space for the battery. Making the SIM smaller is one of those compromises. No one forces you to cut the SIM. If your service provider is a valid distributor of the iPhone they should have Nano SIMs for exchange. If they charge you for exchanging it that's a burden the ISP forces on you, not Apple.
