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. Perhaps, you are interested in how to screen record on iphone 12 then follow this link.

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.

How iPhone user does this will depend on your carrier and location. You can also use the visual voicemail service, which allows you to view voicemail messages in a list to listen to, save, or delete using the voicemail app.

This voicemail app can often cost you extra, so if you have been upgraded to an earlier (or updated) version, you may need new settings sent to your device to make it work. The best way to update these settings manually is to visit your carrier’s website for more information or contact your carrier directly.

In many cases, you can get your settings in a text message from your network. Many networks allow you to request these settings via a message sent from your own cell phone. Your service provider will then respond with a message containing the new settings, which you can then apply to your device.

Is iPhone Voicemail the Same as Visual Voicemail

With visual voicemail, your phone or computer presents a list of voicemail messages with additional information:

  • the caller
  • duration
  • ability to listen to, delete, or archive
  • from the application in any order. This feature means that you do not need to call your voicemail system to listen to all the messages left in sequence.

The very first smartphone to support visual voicemail was Apple’s iPhone in 2007. Today, you can activate visual voicemail on almost any smartphone as long as your carrier offers the service.

I suspect that Apple will provide a way to disable voicemail transcription in future updates. When that happens, we’ll be sure to update this post with how to disable voicemail transcription. However, you can disable it by going to your cellular carrier’s website, such as Verizon, and selecting the option to disable it that way.

How Waterproof is the iPhone 12 – Guide for Users

One of the most controversial features of modern smartphones is water resistance entering the body. On the one hand, this is a nice bonus to a large set of advantages of the gadget. On the other hand, it is the absence of guarantees from the manufacturer in the case of flooding the device. Now let’s find out how waterproof is the iPhone 12 and what are the weaknesses of water resistance in iPhone 12 Pro Max, and whether it is worth exposing it to this kind of exposure.

What Kind of Waterproof and Dust Resistance Does the iPhone 12 Pro Max Have

Experts and enthusiasts have found a semblance of protection against liquid penetration in the iPhone 6s. Apparently, at that time Apple was already preparing for the necessary certification of gadgets and tested some of the developments.

How Waterproof is the iPhone 12 - Detailed Manual for You

Officially, water resistance has become a feature of the iPhone 7 and iPhone 7 Plus. Then Apple smartphones complied with the IP67 standard. The developers promised the water-resistant of gadgets when immersed to a depth of 1 meter and lasting up to 30 minutes.

The iPhone 8 and iPhone X received a similar level of water-resistant a year later (the same protection parameters were found in the iPhone XR and iPhone SE 2020).

In 2018, the flagship iPhone XS/XS Max models were protected against liquid penetration by a more serious standard IP68. According to the specifications, the gadget could withstand immersion up to 2 meters for up to 30 minutes.

The 2019 flagships iPhone 11 Pro/11 Pro Max also received support for the IP68 standard, but the manufacturer allowed immersion to a depth of up to 4 meters for up to 30 minutes.

The entire lineup of devices in 2020 (all iPhones with the index 12) again passed IP68 certification, but the specifications indicate a possible immersion to a depth of 6 meters for up to 30 minutes.

The most important thing that has not changed over time – the lack of warranty in case of flooding the gadget. This phrase is present in the specifications of all iPhone models (including iphone 13 vs iphone 12) since 2016.

In this way, the developers have secured themselves against millions of smartphones that have drowned in service centers. It is almost impossible to repair such devices, and replacing an iPhone with a new one in such a case would be very expensive.

It turns out that the smartphone has a characteristic, but the manufacturer is not responsible for it.

How Do They Test the iPhone XS Max Waterproof Protection

To understand how water resistance works in iPhone 12 Pro Max, it is necessary to understand how it is tested and certified.

In order to obtain the appropriate certificate of the desired IP category, a test batch of gadgets is tested under strictly controlled laboratory conditions. The test devices are placed in a container of fresh water and immersed very slowly to the desired depth.

After 30 minutes, the iPhone 12 is just as slowly removed from the water and tested for performance.

Here we see three key differences from real domestic conditions.

  • First, the temperature and humidity in the laboratory rarely exceed 20-22 degrees and 50%, respectively. In everyday use, we can get the iPhone 12 wet in the summer during a serious heatwave without cool air, during a trip abroad in a country with high humidity, or in other excellent conditions.
  • Secondly, the testing is done strictly in freshwater, and in actual use, the iPhone 12 often ends up in a swimming pool (with a lot of chemical elements) or in the sea (with a lot of salt). Such impurities will adversely affect the moisture protection or settle on other unprotected elements.
  • Thirdly, in real conditions, the iPhone 12 will go to the bottom or reach the surface much faster than in the laboratory. The water pressure on the gadget will change sharply rather than evenly, which can also be a decisive factor.

These three differences do not allow you to hope for a successful outcome of a “swimming” smartphone in real life.

Even during the closest to real-life tests conducted by bloggers and enthusiasts, new gadgets with the highest possible parameters of moisture protection are used. At the same time, no one tells about the further fate of devices that have passed such a test.

Most often, it is not the very first immersion of normal wear in water that is destructive. During the debut “dive” iPhone 12 receives a certain dose of chemicals or salts, which subsequently have a negative impact on the protective pads or unprotected elements. And the subsequent dives after a certain time prove to be fatal.

What are the Weak Points of Water Resistant of iPhone 12 Pro Max

Now let’s take a look at what exactly is the water-resistant and normal wear in iPhone 12 Pro Max.

How Waterproof is the iPhone 12 - Detailed Manual for You
How waterproof is the iPhone 12

Let’s look at all the holes in the case, through which the liquid can get into iPhone 12 Pro Max.

1. SIM card tray. The good fit of the parts and the presence of an additional seal allows the new smartphone to easily tolerate contact with liquid in the place of the opening tray.

However, over time, the rubber seal loses its elasticity, and sometimes even stretches. In this case, each removal and installation of the SIM card turns into a painful procedure.

An iPhone on the secondary market may be sold without this rubber seal at all.

2. The SIM card tray pusher. This miniature element is also equipped with a protective gasket, which is pressed inside the case under pressure and is restored after the tray is removed.

As a result, replacing the SIM card too often will lead to rapid wear and tear of the gasket on both the tray and the pusher mechanism.

3. Physical buttons on the body (volume control, power and silent mode switching keys). Here, too, there is a rubber seal, which shrinks and expands as the buttons are pressed.

The keys are pressed much more often than the SIM-card tray is removed, which means that the gasket can start to leak moisture faster.

4. Lightning connector. The hole from the inside is sealed from the rest of the stuffing smartphone. In addition, there is software protection, which is able to detect a short circuit of the contacts and disable potentially dangerous charging.

The user will receive a warning; after which they will have to dry the smartphone or ignore the warning by turning on charging immediately. If the iPhone is completely discharged after getting wet, the software protection will not work and there is a risk of shorting the contacts while charging.

Even with this level of protection, ingestion of saltwater can lead to oxidation of the contacts with further problems.

5. A protective layer between the screen and the case. The composite design of a smartphone involves the assembly of two main modules: a frame with a back cover and a front panel with a screen. An elastic rubberized seal is installed between these elements.

This is a rather weak point in the whole system of moisture protection. The gasket is disposable and in case of opening of the case must be replaced by a similar one. In addition, the thin layer wears over time, from temperature, crushing and twisting of the case, from bumps and falls, from particles of moisture and dust that have fallen on it.

Depending on usage conditions, this gasket will keep its properties from 6 months to a year. Do not expect that after a year of use iPhone will not let moisture inside.

6. Openings for speakers and microphone on the bottom face. Initially, there is a porous seal between the case and the stuffing. In addition, the holes themselves are covered with a very fine mesh, through which virtually no liquid penetrates

Even if moisture does seep in, it will settle on the speaker diaphragm and not damage the rest of the stuffing. The exception, as in other cases, is saltwater. It can oxidize the contacts and damage the diaphragm.

In addition, outside elements in the bottom of the smartphone are protected by plastic dividers and critical parts are encased in epoxy. Even if the speakers, the microphone or the Lightning port leak a small amount of liquid, it won’t have too much of an adverse effect on the rest of the device.

7. Speaking speaker on the front panel. Here the situation is complicated by the too dense layout of the elements, which are hidden under the “bangs” of the device. In a small area, there are several important sensors and a smartphone camera.

All this is protected only by a fine mesh, covering the speaker. Liquid penetration, especially under pressure, can damage the nearest modules of the device.

Particularly critical will be the breakage of the Face ID sensor system. An inoperable face scanner significantly reduces the value of the smartphone on the secondary market or results in a very expensive repair.

The sensor itself is not replaceable, because it has a hardware attachment to the motherboard. This is necessary to ensure the protection of data on the device.

As a result, you will have to work with the gadget without Face ID or invest in the replacement of the sensor and the motherboard, which will account for most of the cost of the gadget.

Many service centers confirm that it is the Face ID sensor that most often fails as a result of moisture. This happens either when moisture is trapped under slight pressure through the mesh speaker, or through a worn gasket around the perimeter of the case.

Otherwise, a new gadget that has no worn elements and has not been opened for repair is well protected against moisture for up to one year.

The Apple smartphone lineup has this water-resistant and dust resistance:

iPhone 6s and older devices water resistance: not designed for immersion in water and get liquid damage.

iPhone SE 2020/XR/X/8/7 water resistance: up to 30 minutes in a maximum depth of 1 meter.

iPhone 11/XS/XS Max water resistance: up to 30 minutes in a maximum depth of up to 2 meters.

iPhone 11 Pro/11 Pro Max water resistance: up to 30 minutes in maximum depth up to 4 meters.

iPhone 12/12 mini/12 Pro/12 Pro Max water resistance: up to 30 minutes in maximum depth up to 6 meters.

As you have already seen above, several factors can affect the decrease in water resistance.

It can be different from the laboratory conditions under which the dive takes place. The chemical composition of the water, the temperature and humidity of the environment, the pressure exerted on the smartphone. Even the deepest tests do not provide guarantees against trivial coincidence and human error.

During the life of the iPhone 12, it is subject to natural wear and tears. The case is periodically squeezed and twisted, the smartphone is heated to high temperatures, the seals (like the rubber on the SIM card tray) are worn and stretched.

Even drying process an iPhone 12 that has been left in the sun or charged with wireless charging can cause the protective seal to warp and further allow moisture to enter the case.

In any other complex device or mechanism, the rubber elements are considered expendable. This is why we regularly change the gaskets in a car or perform a wristwatch repassage. In the smartphone industry, such procedures are not yet available due to the limited average life span of the iPhone 12.

Such water resistance exists more as a precaution than as a chip for daily use. The manufacturer denies warranty service in case of moisture ingress in the case, which makes the function very specific.

IP67/68 water resistance, in most cases, will save the iPhone 12 after accidentally getting into the water. But regularly exposing the device to such exposure is definitely not worth it.
