The network is missing. At first I thought that contacts or SIM cards were buggy - I cleaned it with an eraser and that was not the point. Someone recommended changing sim cards, but shoved them into an old Nokia 3310 and it turned out that everything was working. What the…

The first two months the flight was normal, until one fine morning I saw more than one network on both sim cards. It was written or not registered, or that they say that in general there is no SIM card in the smartphone - which greatly upset me! But it was — soooooooooooovsem in another!

This material - for two sim smartphones(Solution for Samsung DUOS). After making sure that it was not about the sims, I did full reset phone - and it turned out to be in vain. It wasn't the same thing! And in what? But why does the network disappear? Very simple answer:

1. Go to "Settings" -> "Network" -> "Mobile networks" ->
2. On the second sim, put a tick in the same way: Put a tick: Only 2G networks!
3. The phone will swear: Two SIM cards cannot work simultaneously in 2G and 3G mode! The second SIM card will be switched automatically to 3G mode "YES" "CANCEL"
4. And this is where the main ambush lies! If you press "YES" then the first SIM card is again 3G - again glitches and problems and loss of connection. Click "CANCEL", not "yes"- and Tick ​​REMAINS CHECKED .
5. So - both SIM cards are now 2G! Checking, carefully exit this menu and press: "Settings" -> "Phone Details" -> "Status" -> we look at the lists 1 sim and 2 sim - Yeah, in both the connection type: EDGES (or both GPRS) - but why can't I do it the same way!
6. This is half the trouble, now we go in "Settings" -> "SIM card manager" -> look at 1 and 2 SIM cards! On one - on the first you need to do: Network Selection - Automatic, on the second - Automatically. Do you think everything? But no! If we choose an operator: For example, Beeline and the inscription “the phone is registered on the network” pops up, then if you put it in the “radio shade” (leave it without communication), your SIM card will fall off again - and it will be written: not registered on the network and by no machine - WILL NOT PICK UP by itself !
7. How it can be determined: You will NOT be able to call - it will be written: Ending an MMI session Do you think it's over now? No, not everything!
8. Reboot your Samsung and boot again. We climb: “SIM card manager” -> “Registration on the network” -> “Search for the network” (Search for a long time) -> We choose not “ automatic selection»! a Beeline, MTS, Megavon ) And so on both sims we click in turn!
9. We also remove the checkboxes: Make both SIM cards active " and put " Receive calls on both SIM cards » fuuuuuuuuuu! All by trial and error!
   
10. And reboot and enjoy life and forget this nonsense like a bad dream!

And many beat the phone, knock on it, solder the contacts on the sims, carry them in for repairs, change the sims! And the only problem is that Samsung can't switch between 2G and 3G network (or the network does not want to switch Samsung)! And if you get into a cell where there is no 3G, but what is there - there was 2G and now - only GSM - then the phone cannot return to its previous mode - and because of this it is buggy, up to ... enter the PUK code even!

A typical problem of arrogance A) Co samsung side+ B) From the side of the operator(s)! Problem solved! Samsung with two SIM cards is beautiful, honestly 🙂

PS: How are things like this still going on: Rosexpertiza and RES? So here it is! Ep ... 3 days! I wanted to shoot myself! What for? Software-hardware connection problem solved! Hmmm... and bringing in (even) warranty repair— the problem is not identified remains! Sims connect very well!

What about PSS? NOT SS? 2. Possibly suitable for other Android phone models: LG, ZTE, Samsung DUOS all dual sim models! Good luck to everyone - and remember, the technique has nothing to do with it, all the playful handles want to press somewhere ... Pressed 2G and pressed YES - that's it ... think one Sim died ?! And there is nothing like it - read above)))) how to treat!

Lost network

A possible cause may be a failed radio path. This device quite complex, since it is connected with it a large number of various elements. Therefore, at home, it will be impossible to determine the cause and carry out repairs. To find out the true cause of the breakdown, it is necessary to conduct a complete diagnosis of the device. It is worth contacting a specialist who will not only help to find out the cause, but also eliminate the breakdown.

The device began to catch the network badly

This option initially assumes a breakdown of the antenna. This problem occurs quite often, since the antenna itself is a rather fragile element of the phone and deforms when dropped or hit hard, which leads to breakage. To solve this problem, it is worth replacing the antenna completely.

Network drops intermittently

In most cases, the owner himself becomes the culprit of the situation. telephone set, since even a small amount of moisture that has got inside the device can seriously affect its further operation. It is necessary to carry out a complete diagnosis and, having identified the cause, immediately eliminate it. It is impossible to delay with this process, since the ingress of moisture into the apparatus leads to the formation of corrosion.

The phone shows that there is no network and does not look for it at all

This option is possible if there is a problem with the device program, in other words, the device program has failed. The only way out of this situation is to flash the device. It is important to contact a specialist, since it is unlikely that you will be able to reflash the phone yourself.

Qualified specialists will help to carry out high-quality diagnostics, identify the problem and repair the telephone set.

However, if the phone does not catch the network, this does not mean that the device is broken. Before drawing conclusions, you need to check if there is a signal. The corresponding icon should be displayed on the main screen. It often happens that the user selects a network that is not supported by the operator. All the necessary information about it is in the gadget menu. And this is only one reason, but there are others that will be discussed in this article.

Does not catch or search for a network

Not the most pleasant reason, which can lead to the fact that the phone does not catch the network and stops looking for it, is a serious breakdown. This happens when an amplifier breaks down in the gadget that increases the power of the transmitter. To return the machine to working condition parts will need to be replaced with new ones. It is not recommended to carry out these actions on your own, as it may be necessary to check other details, for example, the SIM connector, controller, antenna, and others. In order to be sure of the result, it is better to contact a qualified specialist.

The network suddenly disappeared

When the phone does not catch the network, it is worth looking for the reason in its internal details. If the signal suddenly disappeared, then this may indicate a breakdown of the radio path. This element is essential for the operation of the gadget. It is connected to large quantity details. It is impossible to check its performance at home, as well as independently make repairs. In order to be 100% sure that the problem is in the radio path, you will need complete diagnostics device. Such services are provided by service centers or workshops specializing in phone repair.

The phone does not catch the network well

If the phone has a signal from a cellular operator, but it is either very weak, or disappears altogether, and then recovers on its own, then most likely the reason is in the antenna. This breakdown is by far the most common. Although the antenna is not visible externally, it still remains a rather fragile element. For example, if the phone is dropped, deformation may occur. Accordingly, it will lead to breakage. Repair consists in replacing the antenna. The work is simple and does not require large expenses from the owner.

Intermittent signal loss

Unstable signal, the phone does not catch the network? Why does this happen even with new devices? In most cases, the reason is quite banal - an unscrupulous attitude with the device. Not every user is aware that even a very small drop of water, getting inside the device, can lead to precarious work phone. The consequences are unpredictable.

In this case, the owner is advised to take the gadget to a service center, where specialists will make a diagnosis. This will determine the exact reason why the loss of signal occurs. If the penetration of moisture into the device is confirmed, the master will clean all contacts to prevent corrosion.

It is important to remember that if you do not clean the device in a timely manner, then soon malfunctions will appear much more often, affecting other elements.

Cellular network missing

What to do if the phone does not catch the network? No signal icon is displayed on the device screen. The machine does not attempt to connect to the network automatically. Every second owner faced this problem. modern smartphones. Most often the reason is software failure. If rebooting the device did not fix the problem, then you will have to take drastic measures, that is, reflash the system.

In order to be sure of a positive result, it is recommended to consult a specialist. But at present, firmware for all brands of phones can be found on the Internet, so advanced users do these manipulations on their own. Each person, having decided on this step, performs actions at his own peril and risk. After flashing the system, the gadget is automatically removed from the warranty, so if something goes wrong, even experienced craftsmen will not save the phone.
