Have you ever needed to swap the SIM card in your iPhone and weren‘t sure how? If so, you‘ve come to the right place my friend! By the end of this guide, you‘ll be a SIM card removal expert.
We‘ll start with some background on what exactly SIM cards are and how they evolve. Then I‘ll walk you step-by-step through the process of taking out and inserting a SIM card on any iPhone model. You can even learn how to access your vital SIM details right from the phone interface.
And no worries if you recently upgraded to an eSIM – I‘ve got you covered there too!
Stick with me and you‘ll have all the SIM-related answers you need. Let‘s dive in!
A Brief History of SIM Cards
Early cell phones in the 1980‘s actually embedded subscriber details right on the device hardware. But around 1991, the SIM card was invented allowing mobile users to conveniently switch between devices by transferring a small smart card.
The name SIM stands for "Subscriber Identity Module" and that first generation of cards were quite large – similar in dimensions to a credit card!
Over the next two decades, SIM cards evolved getting progressively smaller and more advanced alongside mobile phones. By 1996 the mini-SIM debuted to power the early flip phone era.
Then in 2003 micro-SIMs arrived allowing over 5x more surface-area for chips compared to mini-SIM despite an up to 75% size decrease! This kicked off the smartphone revolution.
Finally in 2012, the nano-SIM made its entrance with the iPhone 5. Being only 12.3 x 8.8 mm in size but with the same chip surface-area as micro-SIM, it enabled apple to produce their slimmest device yet!
And now in recent years, the latest iPhone models are doing away with physical SIM cards entirely – using eSIM technology instead. More on that game-changing shift in a bit!
How Do SIM Cards Work?
Every SIM card contains a tiny proprietary computer chip along with some flash memory. This securly stores your unique subscriber identity profile including details like:
- Your assigned telephone number
- Contacts list
- Text messages
- Carrier network account information
When inserted into a phone, the SIM card allows the device to connect to the cell towers belonging to your mobile carrier. It effectively authenticates that you belong to that network.
Think of a SIM card like the key that starts your car. Without it, you ain‘t going nowhere! Well at least not via the carrier cellular system. You could still use WiFi…
Additionally, some SIM cards can retain a small amount of data like contacts and messages. Though most modern phones now only use it for authentication, storing personal info in the phone memory instead.
Either way, the SIM makes it easy to "move" your account. Simply take it out of one phone and put it in another compatible device to switch numbers!
Common SIM Card Types
Up until recently, three main physical SIM card size formats existed:
Standard – The original full-size SIM used from 1991 to 2003
Mini – Offered reduced thickness for flip phones from 1996 to 2003
Micro – Dominated smartphones from 2003 to 2016
Nano – Fit the thinner iPhone 5/5S form factor starting 2012
Another important specification is SIM shape. The standard cards are punched-out, mini-SIMs have a corner chopped, while micro and nano are etched to be smaller. This prevents inserting the wrong size into incompatible slots!
However, most latest premium phones now rely on embedded eSIM technology for network authentication:
With an eSIM, there is no physical card to insert or remove. Your account details live digitally in the phone software itself.
Let‘s take a closer look at the game-changing benefits of eSIM and how they compare to classic SIM cards.
eSIM vs Physical SIM Card
After 30 years, traditional removable SIM cards are finally fading into history. eSIM offers some clear advantages:
Benefits of eSIM Technology
- Enables dual SIM functionality on a single device
- Makes carrier switching easier than ever
- More resistant to damage from dust/moisture
- No physical SIM tray = less mechanical wear
Benefits of Physical SIM Cards
- Supported on older or basic phone models
- Can be manually transferred between devices
- Visible confirmation the card is properly inserted
For most modern device owners, eSIM is now clearly the way to go. However removable SIM still plays an important role in keeping older or basic phones connected.
And in some regions, smaller prepaid carriers rely exclusively on classic SIM card authentication rather than supporting eSIM accounts.
Next let‘s get into the nitty gritty of actually removing a physical SIM card from various iPhone models step-by-step.
Removing a SIM Card From Your iPhone
Getting a SIM card in or out of an iPhone is thankfully pretty straightforward. But first you need to know where the tray slot lives on your particular model.
Apple has moved it around a bit over the years:
- iPhone 14/13/12 – Left side of phone
- iPhone 11/XR/XS/X/8/7 – Right side
- iPhone 6s and Older – Top side
For visual assistance, Apple provides excellent support diagrams showing exactly where the slot is located.
Once you‘ve found it, carefully insert the SIM ejection tool into the circular hole next to the slot, apply light pressure until you hear a click, then pull to release the tray.
This plastic tray holds the SIM so be very gentle sliding it fully out to avoid cracking. Then you can safely remove the SIM card from the tray.
When you‘ve swapped or replaced your SIM, simply reverse the process inserting it back into the tray, sliding both into the slot gently until it clicks securely in place.
And we‘re back in business! Those are truly all the steps for safe and easy SIM card removal and replacement in an iPhone.

Accessing Your SIM Details
Occasionally you may need to reference the associated SIM card number – called an ICCID – without actually taking out the card.
Here are the two easiest ways to access it:
For Already Activated iPhones
- Open the Settings App
- Tap General > About
- Scroll down to ICCID to see your number
For New/Unactivated iPhones
- From Hello start-up screen press (i) icon
- ICCID is shown next to IMEI
And same goes for eSIM – these screens conveniently display your eSIM ID number known as the EID if using that format instead.
Super handy to keep in mind if you ever need to reference those details!
Proper Care When Handling SIM Cards
While SIM cards themselves are small and durable, their connectors can be damaged by dust and their data very sensitive. Follow these best practices for keeping your SIM safe:
- Always work over a clean, well-lit surface
- Avoid touching gold contacts
- Handle gently by edges to prevent bending
- Use ESD bag for storage to block static
- Never discard – contains private account data!
Be extra careful whenever directly handling to prevent loss or damage. A damaged SIM can disable connectivity and compromised SIM data poses security risks.
If you do happen to lose or break your SIM, immediately contact your carrier to suspend service temporarily. They can also provide a replacement SIM card – usually best obtained by visiting a brick-and-mortar store location for fastest processing and activation.
