Whenever I try to enable Mobile Data, it doesn't do it. For enabling mobile data, I have to either
Change preferred network type (to 2g then back to 3g etc.)
Reboot the phone
After performing any of the above thing, it starts working. But again after some time has passed without the mobile data being used (after using WLAN), if I try to enable Mobile data, I have to perform any of the above step.
Any ideas how to solve it?
Its a glitch, try switching to airplane mode for 1 minute and then turn off airplane mode
Thanks for the tip with the airplane mode. Unfortunately it doesn't work for me. Maybe I only activated it too briefly and switched it back too quickly.
At the moment I am helping myself with a Tasker profile, which I run manually using a button if Tasker does not run it automatically.
Basically, I still hope to find the cause of this malfunction, since it should switch cleanly on its own and activate mobile data under 4G. Flight mode / switch between 3G + 4G / restart are all just workarounds.
IMHO it should be switched / activated cleanly by the system. So far it has worked with all other telephones as well. (Partly also Xiaomi Phones with MIUI)
My current system is MIUI 12.5.9. The error also occurred in the previous versions.

About 3 days ago I reinstalled Settings Profiles and setup some schedule for phone to go to Airplane mode at night, after I woke up, phone exited airplane mode but was unable to connect to data network, I tried to disable data network and enabling, then tried to delete apn and setting it to default, finally I went to debug mode and tried to connect to 3g from there which it does but disconnects right away, sometimes it will stay connected for some time but will disconnect. I also tried to use different sim cards from tmobile to att, same issue.
When it first started haping I was on fr91 rooted rom, so I decided to swich to new cynogen mod, which I did by wiping and installing and I still have the same issue, does anyone know how to fix this?
Did you try this?
In phone hit * # * # 4636 # * # * Phone Info and try to set the WCDMA preferred to WCDMA only.

Yes I did. I tried every combination possible and sometimes it works for couple of hours but then it will disconnect again. Do you know how to reset antenna? I see an option there but no idea how to change it.
Figured out the issues
Switchpro widget has 7 places to put different functions on it, you can make into 5 or you can make it show 7. if you had data function off and the you deleted or moved the widget, data portion will not work. so if any of you have an issue make sure switchpro is not turning off your data..
Im sure there are many people out there who bought their tab second hand on craigslist or ebay and ect.... thats my situation.
i have a galaxy vibrant, and am on the simple mobile unlimited plan. ($60 unlimited everything) so i dont use verizon because i tether to my tab using the vibrant. i noticed the radio taking up a good 8% of my battery after 3 hours of standby. so i wanted to disable this since i dont use it. after trying many different apps like apn on/off and others, i realized none work. then i found the solution to be ridiculously simple.
1. go to settings
2. go to wireless settings
3. Hit Airplane Mode ( But that kills wifi so damn)
4. go to wifi settings
5. Enable wifi (It enables wifi while still under airplane mode, thus killing the cdma radio)
there dilema resolved.
now im getting an extra 20% battery life over a full discharge. <3
good luck
Great Idea. THIS SHOULD BE A STICKY.
Just set up my Galaxy...
Thanks.
Good instructions for newbies, but an old topic. And you can't use bluetooth when you are in airplane mode.
Maybe switch.off mobile data. Also when not using toggle wifi off

Or just dial *#*#4636#*#* and switch the radio off
I have to do after each reboot
Thanks guys!
You can also use the Airplane Mode Wi-Fi Tool app, I've been using it for awhile and it works perfectly. It sets it to airplane mode and allows you to use wi-fi in airplane mode. It also stays after reboot. It also allows you to use bluetooth in airplane mode, though I haven't tried this feature yet.

I have this strange issue that has been with me almost since the beginning. I haven't been able to trace when it happens, but it now seems almost 100% of the time.
I only have WiFi in the house (wifi6, if it matters). If I go out, I only have 4G (I left only 4G and disabled 5G). I have no data until I put the phone into airplane mode and back, or I disable and re-enable mobile data.
Same thing when I go back in the house: no data until I disable and re-enable WiFi.
I've disabled the option for 'always-on mobile data' or similar, it's quite a battery drain if there's no cell signal.
Seems like a very strange bug, I don't have this with any of my other phones.
So you have both WiFi and 4G enabled and they don't switch seamlessly?
Exactly. I always have to restart each one of them, usually by toggling airplane mode. Was wondering if anyone else ran into this issue.
Ok this really is strange. There are 2(!) different toggles to enable data switching between WiFi and 4G, but for me it works flawlessly without them! As soon as I get out of my home WiFi range, 4G kicks in, and when I get in range again, the phone connects to my WiFi...
Hi, i have this problem too but it's not always.
I have a wifi 6 router too.
I also have problems switching from wifi to 4g. Need to toggle airplane mode on/off. 5g deactivated. No wifi 6 here.
I always assumed my vpn is causing problems during the switch to 4g. But hearing others have the same problem i would assume its zenfone problem.
I never had any issues in this area with my ZF8. With the option to have cellular always on I could walk out of my WiFi zone during a video call and no drop or short pause would appear.
With this off the network need a few second to work, and some apps need to be refreshed/restarted to gain connection. Never needed to toggle connection for this to work.
Maybe a reset would be enough or check for updates.
Ah, exactly! It does not necesarily need a network restart, but some apps just lose connection for a while, which can be from a few seconds to >1h. Which is even more weird as the icons are showing full connectivity. I would go out of the house, do stuff, come back later and I would only get the notifications when I'm back inside the house.
Rarely I had the connection drop completely (no signal) when switching, but I haven't noticed this happening since the last update.
Hi, I have an S21 Ultra 5G, (SM-G998B)and I have problem about 1 month ago. When I am connected to a wifi network, icons 4g is turn on and mobile data stop work. Only way to turn on mobile data is restart phone. What is the problem? I try everething and hard reset but problem not solved. This happens almost every day once or twice
Not sure I understand....the phone will NOT use mobile data when on Wi-Fi. You can force it by going in developer mode and boost speed by using both, that is not the default though. ("Mobile data always active")
"Mobile data always active" is turn off but 4g icons is active in same time as wifi network. After that I turn off wifi and mobile data not work but 4g icons still turn on.
I found out what the problem. Every time after sharing the mobile network via hotspot, when I go to Sim manager and turn off Sim 2, both icons appear and the mobile internet stops working.
1. Turn on sharing mobile data (from sim 1) via hotspot. (sim1 and sim 2 active)
2. Turn off sharing data via hotspot
3. Connect to any wifi (after connect to wifi, only wifi icons appear)
4. Go to sim manager and turn off sim2.
5. After that, both icons (wifi and mobile data) appear and mobile internet stops working.
Does this happen to others?
I would like to have my mobile data always on on my Android.
Is there a way of forcing it permanently on?
What I need is a situation where even if the user of the phone switches the data off, it quickly switches itself back on or just refuses to switch off.
Or if there is a third party app i can use to force data on i would appreciate.
You can find this setting in the developer settings. No need for root
The one in developer mode is one that keeps Mobile data on even when WiFi is on.
But what I need is a situation where even if the data on/off toggle in settings is switched off, it would automatically switch itself on or just refuse to switch off.
