Originally a little plastic card that fits into your phone, the term “SIM” stands for “subscriber identity module.”
It allows you to utilize data on your phone, send and receive texts, and save information, including your cell number.
In addition to storing contacts and phone numbers, SIMs provide seamless phone switching — all you have to do is remove your old SIM card and insert it into a new one.

What is an electronic SIM card?
However, the purpose of so-called eSIMs is to replace traditional physical SIMs (the ‘e’ stands for embedded, in case you were wondering).
An eSIM is a tiny chip that is installed in your phone as opposed to a conventional card that may be removed. It cannot be taken out and placed in another phone.
An eSIM’s data can be written again. This implies that switching networks doesn’t need taking out your SIM card and replacing it.
It will probably be some time before eSIMS totally replace plastic SIMs. Currently, eSIMs are most frequently utilized as a dual-SIM phone’s second SIM.
What Benefits Can an eSIM Offer?
Making network switches is simpler. Changing cell networks is significantly simpler with an eSIM. You may switch to a different network over the phone or online, eliminating the need to buy a new SIM card, wait for it to arrive, and then insert it into your phone. Additionally, you won’t have to search for a SIM “ejector tool” in order to take the old SIM out of your phone.
You can switch to a different network momentarily. One eSIM may hold up to five virtual SIM cards at once. This implies that in the event that you find yourself in a location where your regular network signal is weak, you may rapidly move between various networks.
Additionally, it eliminates the requirement for a physical local SIM insert, making it simpler to switch to a local network when traveling. When traveling, using a local cell network may often be far less expensive than paying roaming fees to your India network. You’ll also be less likely to misplace your India SIM if you don’t remove it from your phone.
enables you to use several SIM cards. The most evident benefit of eSIMs is that they allow you to have two phone numbers on one device, which is similar to dual-SIM phones that have two slots for conventional plastic SIMs.
If you want one number for work and one for personal usage but don’t want to carry two phones around, this might be useful. You will always be able to receive calls and texts on both numbers, and you will be able to select which SIM card to use for data access, text messaging, and phone calls.
less room is used on the phone itself. The ultimate elimination of the necessity for a physical SIM card and its tray is another benefit of eSIMs. This area could be used by smartphone makers to expand the capacity of a phone’s battery or add other functionality. A phone with fewer holes will be more shielded from dust and moisture, which will reduce malfunctions.
In rare circumstances, it may also be possible to reduce the size of handsets. However, wearables like smartwatches really have a space advantage since consumers prefer not to have a large gadget on their wrist. The Samsung Gear S2 and Gear S3 smartwatches, as well as the Apple Watch Series 5 and Series 4, already contain eSIMs.
What Drawbacks Can an eSIM Have?
However, there are a few possible drawbacks to eSIMs.
Switching gadgets fast is more difficult. Currently, if your phone breaks down, you can quickly take out the SIM and insert it into a another phone, maintaining your contact list and phone number (if your contacts are saved on the SIM).
With an eSIM, this will be far more difficult, even if cloud-based contact and information storage is meant to simplify the process of transferring data across phones.
Nothing to take cover from. Additionally, an eSIM cannot be removed from a device, which might be a drawback if you worry about your whereabouts being monitored. However, as it makes it more difficult for phone thieves to conceal the whereabouts of a stolen phone, this might also be a benefit.
Is an eSIM Present in Every Smartphone?
Only a small number of the newest wearables and smartphones now on the market feature an eSIM. Among them are:
The iPad Pro, the new iPhone 12 series, and the most recent iPhone models from Apple, including the XS, XS Max, and XR
The Galaxy S20, S20+, and S20 Ultra from Samsung
The Pixel 3 and Pixel 3 XL
Motorola’s Razr (which lacks a real SIM card and just has an eSIM)
Samsung smartwatches, Gear S2 and Gear S3.
Series 3, 4, and 5 Apple Watch
Does eSIM Support All Networks?
While some networks may not yet accept eSIMs, they will eventually once this technology becomes commonplace.
Currently, Jio and Vodafone Idea (Vi) in India provide some level of eSIMS support.
