Nowadays new technology has taken place of sim i.e. ESIMS. and you have to everything about ESIMS and its Pros and Cons. The new batch of pixels and iPhones come with dual sim support to physical SIM cards only in China. The rest of the world including India gets one SIM slot and an ESIMS.
- So, what is an e- sim?
- How does it work?
- Is it useful is it a step back what’s Apple and pixel doing here?
How ESIMS functions?
ESIMS stands for the embedded sim. Now think about it for a minute you lose yourself card you go to a local service providers store they give you a new SIM card and tell you it will be activated in X minutes.
I’m sure it’s happened to all of us right. So, what’s happening here basically the card they give us they’re going connect it to our account that’s all that’s the waiting period.
Now, what if instead of Vodafone, Airtel, and Jio are giving us the SIM card we already had a card that they can connect to our account that’s an ESIMS.
The phone comes with the SIM card embedded and the service provider just needs to connect your account with that SIM card.
So, why should we be bothered how does this matter does it even matter well actually it does now one of the most important things with technology is the size the component sizes keep going down and down.
The last flagship phone despoiled a mini sim was released all the way back in 2013. The reason brands went with micro and then nano is to save space that’s how important it is. The same reason why we are seeing headphone jack style, IR blasters, removed health apples even done away with the fingerprint scanners.
When display sizes keep going up the internal components keeps shrinking. Space is at a premium for manufacturers an ESIMS is just 15% the size of a nano SIM.
Now while that by itself is great the fact that a nano-sim is not only gonna take the space of an unashamed but the sim tray the assembly the ejector spring you know everything takes place.
So, ESIMS is much tinier and it really helps save space. okay, I don’t care about size so does it have any other use if that’s your question?
Well, it still does forget phones with smartwatches other tiny devices ESIMS helps them stay connected without having to be tethered to a phone.
ESIMS and its Pros and Cons
Now other advantages include well it doesn’t happen a lot of phones that it get rusted on a SIM slot can lead to a loss of water resistance and embedded SIM helps avoid this scenario.
Now if you don’t care about any of this then there’s convenience switching from one carrier to another it is easy as downloading the app and buying a monthly plan. No more having to go to a showroom getting a SIM card from them at least that’s how it works in the US now.
Either download a carrier’s app or scan a QR code that they give you ESIMS is configured for use. So, if you are traveling to another country and you want to avoid roaming charges in the future, it could be as easy as going to the country downloading enough buying a plant and done.
Now let’s come back to India like I said Airtel has already a big in support for ESIMS Jio does too and given the iPhones and pixels coming out will not have a second SIM slot in India. Expect China others like countries ESIMS function.
Now SM is not without disadvantages every time we change phones we’d have to deal with carriers break your phone borrower friends you’d have to activate the ESIMS.
It’s not as simple as transferring the sim from your phone to your friends it should be a simple process activating it but at least for a while, it will involve calls to customer service.
Which I’m sure will make my life miserable think about it for a minute there’s going to be a near future where I got a deal with Vodafone and Jio every week as I swap phones.
