Why does the Android phone or tablet sees Sims?

This article will tell you how to troubleshoot the work of the SIM card.

In this article, you will learn the reasons why the tablet or smartphone does not read the SIM card, as well as what actions are taken in these cases.

As you know, the SIM card has small size, but it has a certain chip that is soldered to a plastic chip, and is always produced in the same form. Of course, many will think that the production technology of such things is very simple, but it is, but unfortunately even here there is a so-called marriage, so some new SIM cards are not read on your tablet or smartphone.

Of course there are cases when the SIM card slot is in a faulty state, but often it is the wines of the SIM cards themselves.

therefore today we will figure it out what to do if your tablet or mobile smartphone does not read a new SIM card, and what to do in such cases and what actions to do.

What are the reasons for a smartphone or tablet on android does not read SIM card?

The first option, that is, the reason for the slot of the slot on your smartphone, which serves to insert the SIM card to it.

Therefore, if you want to make sure the slot is to blame or not, then simply take another SIM card and insert into your phone slot, pre-tested this sim card on another phone to make sure it is really working.

Also, there are also cases of cases that were to fail the software on the Android platform when it remained only to reflash.

Smartphone or tablet works and reads sims of only one operator

In electronics stores, you can often find various stocks in the form of smartphones or tablets, which have huge discounts, but their work is possible only on a specific operator, that is, the reading of other sims is not allowed.

As such a system has its meaning in the United States, there are similar suggestions very often, and it is mostly promoted when selling Apple iPhone products.

But the smartphones running android also take place in the service list of such shares and suggestions, as this is a very favorable condition for both for you and for the seller.

Be careful! If you buy a similar device on the action from a certain mobile operator, then the smartphone will read only its SIM card. Therefore, if you want to go to another mobile operator for some reason, the SIM card simply does not read, that is, simply will not work.

Of course, you can unlock this binding to a specific operator, but the procedure itself is very time-consuming and harmful, and therefore requires a number of knowledge necessary, and perhaps even the help of specialized personnel, which is related to such a specification and production of such work.

Not working SIM card

If your device reads everything to a single SIM card, but only except one, then a problem in the SIM card itself is clearly obvious here, as marriage is very often found on new cards.

Perhaps you yourself damaged it, but in order to learn this - just inspect the availability of possible external damage. It is necessary to make an inspection carefully and preferably under the magnifying glass to see if there is damage to the chip.

If you have in the proximity of the alcohol, it is desirable to wipe the SIM card to wipe it, why wet the mob and carefully pass the microcircuit. If you have on the map of the so-called condensate, you should wipe the contacts with a dry cloth.

No less important, but the necessary inspection is the SIM card itself, namely her form.

After all, as you understand, there are three standards for the release of SIM cards:

• MINI SIM - This standard has been adopted by Apple, and therefore all their products, including iPad, is issued with this standard. Therefore, many users, as well as the public, are in bewilderment of such a step of Apple
• Micro Sim.
• Nano Sim.

But as you understand, a little later, the idea appeared to leave a sim card without a plate, that is, a purely chip, so it was carried out in a short time, and got the name Nano SIM.

Therefore, you need to find out which SIM card is intended for your mobile smartphone, but it is usually written in technical documentation when buying any phone.

It is also necessary to check the correctness of the pruning of the SIM card, because the contacts of the chips were accidentally affected, and therefore the SIM card does not work.

Let's look at what sizes have SIM card types:

• Micro SIM has 15x12x0.76, values \u200b\u200bare indicated in mm
• Nano SIM has 12.3 × 8.8 × 0.67, values \u200b\u200bare indicated in mm

Possible blocking your SIM card

Often, many very "high" operators block the SIM cards whose users do not use them, or simply do not replenish the personal account on it, which is definitely not profitable to the operator.

Remember one axioma that you have not used any card for more than a month, or did not replenished the balance on it, then it is blocked, and this is a fact.

After the firmware, the SIM card stopped determined

This problem is also registered in many cases when the new version of the Android platform has errors that have occurred during the installation. Therefore, before turning to the operator, you should reflash the device.

By the way, you can also try to solve this problem by dropping your phone settings.

Well, let's summarize today's article in which they told what to do in cases where the phone or tablet does not read and does not see the SIM card
