I have S10 bought in UK dual sim. I have two sim inserted slot one UK and slot two foreign sim. They both were working fine until recently.
For the last two weeks both have started loosing connection to network. It is for few seconds 5-10 times a day. Initialy this was with foreign sim and this morning the same happened with the UK sim.
I have tried all options in sim card manager, mobile networks and to restart the phone. Still the same.
I have dropped phone twice but this was some time ago so I do not think this is related.
Anyone have experienced something similar on any suggestions how to fix it?
Many thanks

Yes, I keep losing data connection. I have bars but no data, I have a U.S. sim and a UK sim. Sometimes turning on/off airplane mode helps, other times I have to restart the phone only to get yet another annoying notification telling me I have no network connection. I just installed the latest update, we'll have to see if it stops.
I was decided to do factory reset as a last resort but I thought that maybe I will start with other options and I did the Reset network settings.
So far all good. For the last two days no single issue with loosing network connection.

Hello.
Having problems with my I8190N. About 2-3 days a go it suddenly lost ability to connect into internet. I can switch data connection on or off, it doesnt make any difference. I have tried to reflash various ROMs and it's all the same, no internet. I get the usual signal bars but no H/G/E marks.
It did not happen after flashing, had CM11 on it for days and I could connect Internet just fine. No carrier limitations either, I can make calls out and same SIM in my old phone can go to internet.
Should I flash the stock ROM/bootloader back and RMA it? Or is there something else I can do? (perhaps known issue and solvable on my own)
Phone is fairly new, bought it in August as brand new.
i suppose APN settings are correct?
you can try to flash another baseband to try with it, what is yours current baseband?
basebands you can find here for N version, XXAMJ ist newest and working for me...
I had the same problem a couple of days ago. It turns out that my problem was the simcard, have you tried to put another simcard in your phone and see if it works?
I have this problem, same with two phones and two SIM cards, both phones are ZTE, both problem SIM cards are on Vodafone, both phones have no problem connecting to data via t mobile sim? This leads me to believe that voda data does not work on zte phones, apn details are correct. Does anyone knowa fix?
finally sorted it........... f'd around with a few different apn's and even phoned up talktalk(same as vodafone network) who confirmed I had the right settings which I hadnt!
Found the correct settings on the geeksquad website. seems i didnt need to bother filling out some of the fields and then wham internet connection straight away!

I have been using my Htc one from the past 2 years using the same sim card. Since i stay in India, the phone goes into roaming mode when you travel across states. So 10 days ago, i travelled to another state and my phone entered into roaming mode from then my phone cannot be connected to the network. I am unable to use the cellular services. Sometimes my phone works fine but the next minute, i loose the signal again. It is not in a stable mode, it keeps loosing and gaining the connection. Neither can i call nor i can text. If the phone gains signal, it happens only for a minute or two after that, it looses the network again.
My sim card is fine since i checked it in other phones. So the problem is with the phone or the sim tray.
What should i do?

Seems strange it happened after / during traveling
I have herd of others putting a piece of tape on the back of the sim to make it a little thicker. be careful doing this though the sim could get stuck in the phone permanently
I bought my Droid Turbo about two weeks ago to use it in Europe. I checked all freq and bands of my carrier and I also spoke with a guy who is using Droid Turbo in my country (Poland), all was ok. I got my phone and before inserting the sim card I updated to lollipop 5.1 OTA. After inserting my sim card the phone detected my sim and connected with network (LTE). I thought that everyting was ok untill I started using Droid Tubo in a daily basis. The phone is constantly switching networks. Its loosing lte signal switching to 3g for example, then to gsm. After a while its reconnecting but not always, sometimes I have to restart. I was trying almost everything: wiping from recovery, wiping via fastboot, switiching network connections by hidden menu commands, changing apn settings... I noticed that my problem seams to be similar to the problem which was solved by 21.44.8 update which: "Fixes an issue that could prevent proper switching from 3G to 4G LTE. Fixes issues that could trigger a dropped call, prevent a call from going through, show that no service is available or show that a SIM card is not inserted" - this is quote from motorola update release note. This quote very well describes my problem. After doing almost everything what I could I decided to ask for your help, because Im starting to think that this is a hardware issue. I am looking forward for your help and will be very gratefull for any suggestions.

Hello, I have almost the same problem. I recently bought DROID TURBO and i was using it w/o any problem for about a month. and Poland is also my country I did everything like you including update to lollipop before inserting SIM card. Everything with the phone was ok until i tried to change cellular bands in menu to see if it will affect battery life in some way.
Unfortunately my Droid Turbo is now refusing to connect to any network. To be exact: it is logging to my network ( i have checked it on the service hotline of my carrier ) but then after about 3-5 sec. signal bars are greyed and no connection to the network. I've tried three different cards from different carriers and with all a have the same result. Now i cannot use my Droid Turbo as a phone ....... i've tried factory reset, cache cleaning, disabling Verizon apps&services .... nothing... Could someone help me/us, do you have any suggestions ?

Hello again.
The only way i've solved this network problem on non-rooted Lillipop is to install new firmware using Verizon Software Upgrade Assistant for Droid Turbo. You have to run this software and use the rapair button then it downloads new firmware and installs it on your phone.
i have same problem.
just flash last firmware with fastboot
Hello. About a 4 months ago i have bought from eBay a note 5 at&t version. I live in Greece and my network operator is WIND GR. The phone works fine but from time to time i get an emergency calls only message. And i can't get and do a phone call. If i restart the phone everything goes to normal. Sometimes it goes on and off by itself (the problem).
Have been anyone experiencing the same issue? If the phone is incompatible with my network operator should it not work at all?
Did you tried to change the sim card? Maybe issue is from sim or from sim slot

My sim is new. When i purchased the phone i have changed my old sim with a new sim 4g compatible.
It happened again. And i am missing calls like this. I will smash it with a hammer
Go to settings, backup and reset, then reset only network settings, see if any better signal

Done that right now. Tomorrow i will get a new sim card and i will post if anything gets better. Thanks for the help.
Update of the situation. I have changed sim card 2 times. It still happening. My phone runs at nougat now and the problem still appears as before at 5 and 6 Android version. I currently gonna change service provider that has better and stronger signal. From what i have discovered. When the phone looses signal due too poor service provider signal sometimes it can't register to network by itself. If i enable airplane mode and then turn it off it comes back. Any clue? If it's hardware issue what can i change?
Should i have at the mobile networks auto detect or manual and my carrier?
Hi guys, I have an issue with 4G after the last dec update. In 4G/3G/2G auto connect mode, usually the receiving data arrow ( v arrow below the 4G symbol in notification bar) gone missing and thus the connection got lost. Only transmitting arrow is visible (the ^ one). I have to wait for some minutes or turn to flight mode and back to get my data connection back.
In the beginning I don't really sure this issue is caused by the latest update, but after I tried nearly everything, including factory reset which is doesn't help, I think that the update is the problem.
I have tried my sim on another phone and it worked normally. I have tried another sim on my note 8 and it got the same problem.
Oh and this is only a 4G issue. My 3G works normally. And before the update, I never experienced this kind of problem.
Two of my friends got the same note 8 and one of them is also using the same carrier as me, but neither of them experiencing this issue.
Anyone can help?
Thanks in advance
I had this issue too, it seems 4g connection only got the problem...,
Problem solved, they replace my device
I have the same problem but seems like in a different way, when I got the phone first time I contacted my service provider to activate the 4G service cause it was inactive on my line due to provider's issues, anyway the phone worked on 4G for only 2 days, after that it kept working on 3G, I contacted the service provider many times but they have no issues with my SIM or handset.
I still don't know what is the problem, is it a hardware malfunction? Is it an installed app? Is it a Samsung Update? I don't know!
have tried getting a replacement sim card, I had same problem in the past and they had by mistake sent a sim that was not 4g, got replacement and problem solved
Well, the problem is that it worked at the fist time on 4G so the SIM was 4G not 3G, but I have just comeback from their store, at the first the technical support did something in their system and switched the phone to airplane mode then turn the network ON back and the deice worked on 4G but after a couple of minutes the phone switched to 3G without going back to 4G, then he advised me that this problem either a SIM or handset problem and it's always 90% SIM problem, so we changed the SIM card and the phone is working on 4G for around 30 minutes till now, I hope it will keep working on 4G
2 days and phone is still working on 4G, it was a SIM card problem
Aoa dear
