I have strange problem with 4G mobile data. So, 4g works for couple minutes and after that stops working. When I switch to 3G everything works fine. I've tried to reset network settings and that didn't helped, then I pulled out sim card and inserted back in also didn't helped, rebooting device doesn't help. So does any have Idea what to do because month ago everything worked fine or to wait for android 10 update to come to my device and maybe that will help with problem since I don't want to reset the device at the moment.

You can try to reset network settings but it may be a signal related problem also or something with the service provider blocking your phone.

Hi. I just bought a new galaxy s from vodafone, but when i tried to use a 3g data connection it just won't work. it works fine with wi-fi connection but if i turn that off (or if i don't use it at all) the phone just won't connect to the internet. i've double checked the apn settings...is there an option to turn the data connection on and i'm just not seeing it? please help...
sometimes it helps to restart the phone
or switch it to airplane mode then back
Did that
i've read other posts for other type of connection problems and i did what u said...nothing...it just doesn't even try to connect...
do you have any other SIM card from friends/family that you can try?
just wondering if it's related to your SIM account, or if it's defective phone
if it is working over wifi there is still something wrong with apn settings or your sim card.. i doubt it is the phone itself.. or you are in an area with no 3g edge.. or wrong phone ie t mobile vibrant on bell or att network

Thank you
I would like to thank all of u who tried to help me... when i was at work today i've changed the sim card with another one with internet on it and it worked so i called vodafone and stuck to my oppinion that it was their fault and finnaly i came across a guy who saw that my account settings were not correct. now it is working. thanks..
thanks for the update
glad to hear you are back online
yes phone companies do mess up very often in our accounts
just yesterday i was complaining to my phone company about something similar
I've got a rooted HTC One on T-Mobile that has worked fine for a couple months. Last week I got a SIM card error a few times and the cell connection was lost until I rebooted, at which point the SIM card error went away and the cell connection (voice and data) worked again.
As of yesterday, my cell connection is not working at all, no bars of service. I do not have a SIM card error displaying in my status bar either. Everything looks fine, just no cell service. It's not a network problem; my wife's phone works fine.
I've tried checking my mobile data settings and pulling and re-inserting my SIM card, but the problem still exists.
Fortunately WiFi works fine so I can still make calls when I have a connection, but obviously this is not sustainable. So... What do I do?
I'm rooted but running the stock ROM. Would it be worth it to flash and wipe? Really seems like a hardware issue to me. Do I have to contact HTC directly about warranty repair/replacement? How long does that process take and is my being rooted going to cause an issue?
Sad

Get a sim card replacement and try that
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
I.have the issue of secure folder as its not there in my cell phone and when i install it from play store and open it but failed to open as it give the option knox mode failed
Hey guys, I finally bought a Redmi note 10 pro like 2 days ago and the mobile data was working perfectly with no issues yesterday night. But today, it just stopped working. Nothing happens when I turn on the mobile data in the control center.
I tried resetting the APN and network settings but that did not work. Also tried restarting with same results.
Then, I tried switching between the LTE, 3g and 2g mode and the data started working only in the 2g mode.
It doesn't work when I switch back to 4g , it's such an annoying issue, especially because I haven't even used it for a week now. Can anyone tell me how to get rid of this problem, please?
Thanks in advance.

i had this same issue a few weeks ago. for me the problem was solved by factory resetting the phone.
Hi guys, i have a problem with my Galaxy S23.
I am connected to wifi at home and mobile data on. But, when i turn off the wifi, the mobile data does not activate. I've checked the APN settings, i call the provider, i reset the network settings ... same issue.
Mobile data is activating only if i call to a short number like *100#. If i don't dial, even the mobile data toggle is on there is no connection.
Can you please help me !
Have you tried a factory reset?
This is the only thing i don't want to do, because i'm going to lose my eSim's.

Fairly certain this shouldn't matter. I think they stay when you reset the phone. You might want to research this more.
Ok, so i did a factory reset. Nothing changed. However, i found an option in developer mode "mobile data always active". This is keeping the data on even if wifi is connected. It is running ok now, but, the battery consumption is a bit higher.
Hi guys,
I'm from Brazil and I'm having the same issue on my S23 ultra.
I use 1 eSIM from Vivo and a SIM from TIM.
When I'm using the mobile data, sometimes it doesn't work even the 4G or 5G are on.
I tried switch between carrier (Tim and Vivo) and both show 4G sign and doesn't work.
There are two ways to restore the mobile data, restart the phone or turn off and turn on the airplane mode. But after some minutes the problem continues.
I went to a Samsung Store and they put a new and clean OS, but after 1 day the problem started again.
I searched about it and I couldn't find a fix to this problem.
I will try to use only SIM and not use eSIM. I read some articles that the T-Mobile was having same issues.
I think it is a chronic problem. Maybe they need a recall or a new update to fix this issue.
Does any know how to fix this problem?
I have 2 SIMs because there are some places that I work that only 1 carrier works.
Problem solved.
I went to the provider and replaced the sim card with a new one. Now it's working without any issues.
