The other day, one of my comrades was faced with the fact that his new samsung phone Galaxy J5 loses network after few hours of inactivity. For example, after lying down overnight in the morning, the device has no network. Only a reboot helps, and then for a short time, the edge - until the next night. The phone was handed over to the service for testing and, after a couple of weeks, it returned as fully functional. I've been digging around on the internet and came across one similar case where the Samsung Galaxy S7 loses network in roughly the same conditions. Thanks to him, we managed to find a solution to the problem! And now I will share it with you.

As it turned out, the LTE / 4G standard is to blame for everything. Or rather, not so much him, but base stations telecom operator. In our case, it was Beeline. For some reason, probably only known to the manufacturer, the phone samsung galaxy loses network if 4G/LTE mode is active. One has only to turn it off, leaving only 3G - the problem disappears and the message "No network" no longer appears, everything works like a clock.

How to turn off 4G Internet on Samsung

Perhaps later, with the release new firmware, the problem will be solved, but for now you have to look for such workarounds. So, to disable 4G Internet on Samsung Galaxy, you need to go to your phone settings and select the "Mobile networks" section:

By default, all available modes are active there - LTE (aka 4G), 3G and 2G. If your Samsung Galaxy loses network - try setting the option 3G/2G:

Then restart your phone and check. In our case, this helped and the problem went away.

Note: If it is the high-speed 4G standard that is vital for you, then you should think about changing the telecom operator. Moreover, now there is an opportunity to do this while maintaining the number.

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 to change sim-cards, but shoved them into the old Nokia 3310 device and it turned out that everything works. 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 select 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 shadow” (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" (Dooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooolong to be a "automatic choice"! 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!

Hello!

My husband recently gave me for my birthday Samsung smartphone Galaxy S4 mini GT-I9190 La Fleur. I have had it for twelve days now. But there are already glitches. Bought it in the Euroset store.

Let me start by saying that for modern smartphones it is not large. Just right for a woman's hand. It is comfortable to hold in your hands, despite the fact that it is glossy, it does not slip out of your hands. The color is burgundy. Floral pattern on the back. Looks pretty nice.
The colors on the screen are bright and saturated.

The smartphone has a dual-core processor. Works pretty fast. It is convenient to access the Internet from it. Screen 4.3 inches. But the width is almost like in Samsung Galaxy Ace(my old phone), but longer. The keyboard is still a bit unusual, it even seems that it is smaller than the previous one.

The battery lasts about three days. Watching how often you use the Internet and talk.

Model with one micro sim card. I had to change the old sim card for a new micro.

Now I am writing about the most important thing, about the glitch:
the phone periodically lost the mobile network. In the first days of use, I didn’t really notice anything. Maybe once a day I had to reboot. After a week of use, I had to forcefully search for a network or reboot the phone 5-6 times a day. As a result, it turned out that he was offline 20% of the time. All this time they could not get through to me. I contacted the store, the consultants replied that it was because of the viruses. Installed an antivirus, but the phone still loses the network. I read in the reviews that this is a disaster for all Samsungs.

Submitted it for examination. Returned after 25 days, marked "No defect found". On the same day, I went to visit another city with the phone. And about a miracle! The phone does not lose the network, it works stably. Until I return home, I can’t find out what’s wrong: either it was repaired (which they shouldn’t have done, since the phone was handed over for examination within 15 days from the purchase), or there is such a stable network that it’s not lost at all. When I get home, I'll test it for a few days, I'll write.

P.S. Sims changed, the effect was the same.

Hello everyone, friends! We are sure that you have come to us because your Samsung Galaxy S8 is losing network. This opportunity seriously complicates life, because it becomes impossible for us to use a smartphone. If you can send a message with grief in half, with the umpteenth attempt, then making a call, or accessing the Internet, becomes a problematic task.

Causes of Galaxy S8 Network Issues

The situation is rare, but it does happen.

So why, sometimes the Galaxy S8 does not see the network, let's look at all the options:

• Be that as it may, you first need to play it safe and restart the phablet. To be precise, turn it off for 10 minutes so that your operator re-registers successfully.
• Depending on the area where you are, the Galaxy S8 clings to different networks. The best option for it is a GSM connection, so we recommend that you go to the settings and specify it in the networks in priority order.
• If the Galaxy S8 does not catch the network well in automatic mode, you need to try to do it manually. In the network operators section, activate the network search mode. If everything goes smoothly and your operator is determined, the connection will be established.
• One, not unfounded, hypothesis is often the fitting of a SIM card to the desired size with scissors at home. Cutting circuit paths is not the best solution however, it is actively practiced. It is this, in some cases, that causes the Galaxy S8 to lose connection at the most inopportune moment. Therefore, we advise you to immediately purchase the appropriate nano-format communication card.
• Alternatively, you can try replacing the SIM card with another one. Suddenly you are a winner in life, and you got a sim card with defects.
• It is possible, of course, to the factory ones, and remove all suspicions from a software failure. However, this will lead to the deletion of all user data, but after that we will already clearly know that the matter is either in the SIM card or in the filling of the phablet.

And if we take into account, then we have already resolved all the issues with the SIM card, and bought a bunch of communication cards. All suspicions fall on the internal pieces of iron, in particular the mass of the smartphone, which is responsible for a good communication signal.
