A SIM card is a smart little card that contains all your subscriber information. What you need to know about the SIM card is – it’s very small, about the size of a postage stamp, or perhaps even smaller.
Your mobile network provider issues this unique little chip which provides access to their cellular network with your phone number attached to it.
The Components of a SIM Card and What They Do
When you insert a SIM card into the GSM standard phone, it is able to utilize all of its functions. The components of a SIM card and what they do:
- The ICC (Integrated Circuit Card Identifier) number: This 16-digit number uniquely identifies your SIM card. It’s usually located on the front or back of the SIM card under a protective label or printed directly on the SIM.
- The SIM (Subscriber Identity Module) card: This is the smart chip that stores all of your subscriber information and personal data like phone book contacts, messages, and service-related data. The SIM comes in many sizes — mini-SIM — a very small version; micro-SIM — even smaller; and nano-SIM— the most recent and smallest version.
How to Insert Sim Card in Iphone 12 Pro Max?
As long as you have your SIM card and iPhone 12 Pro Max ready, follow these 3 easy steps:
- Option 1 – Trim it
If your card is too big for the regular size, then you may have to use a pair of scissors and carefully cut your SIM card down to the right size. Yes, it sounds crazy and dangerous, but don’t worry – if you follow these three simple steps closely, the tiny metal pieces won’t go flying everywhere.
First line up your Nano-SIM or micro-SIM on the cutting board and secure it firmly.
Now, using a pair of scissors, carefully cut your SIM card down to size. Do this very slowly so you don’t accidentally slip and cut off more than you need to.
- Option 2 – Bend it
Now if your SIM is too thick for even the trimmed version, you can try bending it slightly to get it into the device. This might be a little more risky than trimming, but if done carefully, you can get your SIM slotted in with minimal trouble.
Now that you have your old Nano-SIM or micro-SIM cut down to size and your new card bent slightly, let’s put them both together on the tray.
Click on the SIM tray on either side of your device and gently push them out. You can do this with a fingernail or a tool like a paper clip.
Now, gently insert your old cut down SIM into the bottom slot, then place your newly bent card in the top slot. If done correctly, you should hear both of them click into place.
- Option 3 – Roll it
If neither trimming nor bending your SIM card will work, you can go for the third option and roll it up as much as possible. This creates a rounder edge on one side of the card which will make it easier to slide in and out of the devices tray.
Now that you have your old Nano-SIM or micro-SIM cut down to size, your new card bent slightly, and it all rolled up into a neat little ball, insert the ball-shaped edge into the bottom tray slot.
If you’re lucky enough then your SIM will slide in smoothly with no fuss. If not, carefully try again until you get it.
Once your SIM is successfully inserted into the slot, you can now assemble your device back together again.
