I have a galaxy s21 thats ~ a year old.
I am having issues with my 4g/5g connection. The Phone says i have connection but i dont always have internet.
The only way i have found to fix this issue is to either remove cache or go into settings->connections->mobile networks->network operators-> and choose my own network operator manually (this is a temp fix that i have to keep refreshing a few times a day)
I am on verizon.
Any ideas? Could the sim card be going bad?
thanks!

I experienced this problem with two X10, when you are on WCDMA only mode and data connection is active, try switching to GSM mode only. Your data connection will not restore until you enable then disable Airplane mode.
Anyone having this same problem? Both X10 have different manufacturing date and tried it also with different provider but same results
Mine doesn't do that. I do this all the time when I don't want to get over my limit in one day which is 1GB of data...
Mine does the same thing. I have no problem switching from 2g to 3g. But when I go back from to 3g to 2g I have to turn on airplane mode to enable data again. I am running GB 2.3.3 JVB. But the same thing happened on 2.2.1. Being searching like crazy and havent found any solution. Anybody know how to fix this? Maybe its a network problem not a phone problem.
Hi there.
I have the same problem. Do you have any news?
I enabled Data and disabled "2G Only"
But it doesn't use any data!
I paid for a one month...
Help?
Are there any Access Point Names? If your data connection doesn't know where to access the network, it won't.
How can I make one??
Doesn't 3G or Data connection should be automatic??
Go to Settings > Wireless > Mobile Network > Access Point Names
Then menu button, and Reset to default !
Make sure Data Enabled is checked in Mobile Network settings
If reset-to-default fails:
Go to the site of your carrier, they will have instructions to automatically set your phone, and if they don't support your phone, they will tell you how you can set it manually.
Unfortunately nothing works!
I think that phone itself doesn't have 3G!
Or maybe MiniCM....
Because I inserted my SIM into another phone (GS2) and the Data worked without any problems and automatically!
Weird... it's working now!
Maybe after using it in another phones did something?
My guess is: you turned your phone off to get the sim out and turned it back on with your sim inserted again AND data connection on... it probably searched for networks at the sim-initialization during boot. If you had left data connection off it probably still wouldn't have worked lesson learned i suppose. good luck
I don't believe I was having this problem at first, but now when I leave a wi-fi connection at home or at work, and I try to use the data connection it doesn't work. The phone is not switching to the cell towers for some reason. I have to disable data, and sometimes wi-fi, and then re-enable data on the phone to get a connection. Or reboot
This is stock btw. Anyone else have this problem? AT&T support was no help
Edit> Just left my work network to test it out and it switched this time, so it doesn't happen every time. Which makes it more frustrating.
Mine was working just fine a couple hours ago, now I get absolutely no data. This is very frustrating.
Hi all,
I've been using my Samsung Galaxy W for quite a while now, but have only recently given any serious attempt at setting up the phone's 3G connection. I have entered the correct APN data for my provider - using Telstra after unlock - and all settings are correct, as I was initially successful in getting a data connection. However, I ran into an issue when I shut down my phone. Whenever I start the phone back up, I get a glimpse of the 3G icon in the message tray, but after Media scanner has done its thing, that 3G icon then disappears. Initially I could no longer connect via 3G, no matter what settings I fiddled with.
Eventually, I found that the only way to fix the error was to dial *#*#4636#*#*, access the phone info menu, and then to manually enable the data connection. Even more confusing is that when I hold down the power button, my phone states that the data connection is already, and always was, enabled. My packet data is also on... and the phone has not put itself in flight mode. Also, as I said, the APN settings are definitely correct.
Does anyone know why I must manually enable the data connection whenever I restart my phone?
Thanks in advance for any assistance.
Paul
Phone is rooted and running gingerbread 3.3.6
If I go into developer settings and switch off Mobile data always active (in an attempt to save a little power when the phone is on Wifi), I find the phone often doesn't enable data when I leave Wifi. I have to cycle airplane mode to make it do it.
Anyone else finding the same bug? Or even using this setting?
I've had dropped connection issues since day 1, with airplane mode being the only way to restore my connection. And this was with Mobile Data always active set to on.
Who is your Carrier??
Have you noticed similar issues even with mobile data always active?
When I go to building with no cellular and come back outside. The phone doesn't automatically reconnect to cellular, leaving me with no service. What a strange bug.

EE in the UK. Works fine almost all the time so far if I keep mobile data active.
Vodafone Romania, toggled the setting off in dev options as soon as I got the phone. Data switching works fine still.
Try going into the testing menu (dialer code *#*#4636#*#*), select phone information, select 3dot menu on top right corner, try switching around between Europe and automatic. I'm my case ,selecting Europe presented various weird connection issues , biggest of which was that the phone refused to connect to LTE unless I used "automatic".
