How to Put SIM Card in iPhone 12 – Detailed Manual

You have bought yourself a brand new iPhone 12. Before you turn it on, it is advisable to insert a new SIM card. That’s exactly what we’re going to do today, we’re going to look at how to put SIM card in iPhone 12.

What SIM Card is in the iPhone 12

Standard sim cards of large size (rarely used in modern smartphones) are suitable only for the first generation 3G and 3Gs. Owners of second-generation iPhones (4 and 4s) can use a micro sim. All subsequent models use the nano-sim – the smallest available. Its dimensions:

  • length – 12,3 mm;
  • width – 8.8 mm;
  • thickness – 0.67 mm.

To get a sim card of the right size is better in the official center of the mobile operator, so as not to unknowingly damage the chip in an attempt to do it yourself. It is only possible to get a micro-SIM.

Nano SIM is another type of SIM, in which the chip itself has smaller dimensions, so even if you completely cut off the plastic part, you cannot insert it into the iPhone.

Although on the network there are craftsmen who have managed to cut the standard sim card with scissors or a special stapler. Repeat their experience is not recommended if you are unsure of your abilities.

Absolutely all the new models (this is the iPhone 12, 12 mini, 12 Pro, and 12 Pro Max), support two sim cards.

This is a physical nano-SIM and electronic eSIM. Now let’s break down how to insert the physical version in the SIM tray.

How to Install the new SIM Card in the iPhone 12

To begin the setup process, locate the SIM tray and in the box of your iPhone 12, there is a SIM tray with a special SIM eject tool. We take it in our hands. If there are no instruments, there is no need to panic, you can use as a key an ordinary straightened paper clip or any other thin and long object, such as a needle.

There is no need to be afraid of damaging the phone, if you act carefully, nothing will happen to it.

Beware of using brittle elements, they can remain inside the iPhone 12, after which you can’t do without the help of a craftsman to remove them. Try not to scratch the side edge of the smartphone.

The key from any model will work for all others. So even if the iPhone 12 broke, was lost, stolen, etc., but in the future, you do not plan to give up using Apple smartphones, you should not get rid of the key.

The paper clip is effortlessly inserted into the hole, it is worth a little stress-free pushing it inside. Act carefully so as not to damage the SIM tray.

Now take your iPhone 12 and find the SIM slot on the left side (in iPhone 11 it was on the right side). Insert the paperclip into the hole and push until the SIM tray comes out.

Put the SIM card in the SIM tray with the chip up and insert the slot back into your iPhone. That’s it, you have completed the setup process.

How to Put Two SIM cards in iPhone 12

Almost everything in Apple phones is great. But for many users, a significant drawback is the lack of Dual SIM – the ability to install two SIM cards at once. It is possible to add such a possibility to the “Apple” phone independently.

Due to the lack of a dual SIM slot, some Apple fans have to buy two iPhones at once. But there is a cheaper way – you can order a Chinese version of the smartphone or install the necessary module yourself.

If you often have to fly abroad (or had to do it before the pandemic) or move from one area to another, you probably had the need to install two SIM cards in your iPhone at once, because this allows you to reduce communication costs.

In addition, using two cards may be necessary if you need the iPhone for work – then one SIM will be personal and the other work.

Apple devices have never had (and are unlikely to ever have) a Dual SIM feature. That’s why consumers who need this feature usually choose smartphones from other brands, such as Honor. But what to do if you prefer the products of the American giant, and a Dual SIM card is urgently needed?

Consider the flagship iPhone 12. There are two ways to get such an iPhone with two SIMs. The first way is to buy the Chinese version of the iPhone 12 – it immediately has a dual-card cellular data slot. If you have the international version of the device, the Chinese module can be installed in it.

Enthusiast Hugh Jeffries has shown how this can be done, spending only 500 rubles.

A dual SIM card slot can be purchased – it almost perfectly fits the size of the international version. On his channel, Jeffries showed how you can easily and independently replace the standard module of the iPhone 12 with the one in the Chinese version of the smartphone.

No additional gestures, other than the direct installation of the module, are required – the iPhone immediately starts to see two SIM cards by itself. Before you decide to make such an experiment look at the warranty card that was issued to you together with the device – most likely after this manipulation you will lose the warranty repair for free.

Therefore, we urge you to assess all the risks of tampering with the internal device of your iPhone 12.

Possible Problems with Reading the SIM and Ways to Solve Them

Not always, even after successfully opening the device, the SIM works correctly. In rare cases, users may encounter problems. To solve them, first of all, it is necessary to determine the cause.

In some cases, in order to activate the SIM, it will be necessary to connect to the Internet wirelessly (Wi-Fi). If this is not possible, you can also connect the phone to iTunes with the cable included. The program will activate the card itself.

If it is successful, the screen will show the name of the cellular network and the signal strength. If even after this the screen shows “No network detected”, it means that there are technical problems or the SIM card was inserted incorrectly.

Incorrect Installation of the SIM Tray

Problems may occur if the SIM card tray is in the wrong position – tilted to the right or left side. Or the card has been inserted incorrectly. It will be necessary to open the slot again and remove the SIM card.

If the problem has arisen due to misaligned skids, it will be enough to pull them out and remove the SIM card, then insert them back, carefully fixing them in the correct position.

When the sim card is facing the wrong way (with the metal chip facing upwards or the notch on one of the corners not matching the shape of the slot), it will be sufficient to remove the sim card in the correct position.

If you cut the chip yourself, you may be faced with the fact that it will not be notched, and confused about which side to install it will be easy. To avoid this, make marks on the sim card yourself, for example, with a marker.
