Mobile Data - Samsung Galaxy Grand Quattro

My connection was fine, but as I boarded the underground metro, my Signal and Mobile Data was lost(Obvious case)...however after that the signal came back, but my mobile data is not working since then...I restarted the phone...took out the battery, re-inserted sim...but I am not getting back my mobile data connectivity
PS- My device is not rooted...

Ok now...the mobile data connectivity automatically returned...

Maybe it's something with your network providers

Actually the sim was not being detected the following day...the sim was damaged...had it changed

your data connection has everything to do with your data provider, and nothing but connecting with your phone. Set your data connection to gsm only see if it improves.

APN settings or something
I know using my Amaze 4G (AT&T medianet APNs), I get only 9kbits/s up 1000 kbits/s down using the Speedtest.net app.... going through a browser and trying a download tester site, it goes around 1000kbit/s each way.... when I tether, Speedtest.net app on my tablet says 1000kbit/s each way

[Q] Mobile Data Not Working - Ideas?

My S3 is on LF2 unrooted from Thailand.
I got the phone in Thailand and had it running on AIS no problem. Came back to the US for a visit and ran it on AT&T no problem. I get back to Thailand and shut off mobile data until I can re-charge my prepaid account. I do, my data package renews, but the data connection never turns on. No Edge, no H, no H+. I have the right APN and it's lit up green.
I've tried toggling the mobile data on/off, toggling the use data limit on/off.
Any ideas?

Well.. it turned out to be something simple... of course.
The provider had for whatever reason shut off my data service and just had to turn it back on. Not sure why I procrastinated going to the service providers shop to ask them about the problem...
Oh well.. nothing wrong with the phone!
May be a firewall app (visible regular app or unvisible spyware) causing that? Or an antivirus app?

Data connection error

So lately what has been happening when I disconnect my phone from wifi it will not automatically connect to Sprints data network. It says its still connected to 1xRTT (according to SignalCheck Pro) however it then has a pop up saying my phone cannot connect to the mobile data network and says MIP 180 or something along those lines, and I can't connect to Sprints data until i reboot. The 3G symbol will not show up until i reboot and can't connect to data. Im running stock touchwiz not rooted, latest update. This happens pretty much everywhere I go. Any help?
I've come from ATT and have never had an issie of this sort before using GSM phones. Although it could just be because this phones still new?
ok so i got a screen shot of it.
Forget that im roaming and using usb 3.0, that was after the fact it kept telling me this message. I generally have great service where I am, could be cell tower upgrades.
That error code means you need to update your data profile. After you reboot, go into settings and try updating your profile...if it continues contact Sprint.

Had same problem recently and it was due to several tower problems in my area.

Wifi Turned Off unless i Disable Mobile Data

My mother in law got an ATT Alpha and tried to connect to wifi. It will connect and immediately say wifi turned off. When you disable mobile data it enables wifi. That makes no sense... why would the phone favor mobile data.
How can we correct this? I have owned 5 Samsung devices and never seen this.

Beacuse the phone has a Smart network switch feature. You can turn off in the wifi menu.

We turned that off and it still didnt work. we then turned it back on and it didnt correct the issue either. Is a restart needed when you do or something?
Kinda odd that in a home with nearly no data signal from the provider (they use femtocell) that it would prefer the mobile data network over the wifi.
apparently a reboot was needed. thx!

No internet over mobile network, ok over wifi?

Strange thing started to happen few days ago: I don't have internet while being connected over mobile network but have it over wifi. This started out of the blue...
I have unlimited internet via mobile network contracted with my mobile provider so it's not like I've used all of my mobile internet or something. I'm also connected to mobile network as it shows "4G" icon beside my network strength level bar so everything should work except when I try use any internet based app like Chrome or Whatsap, they doesn't work. Chrome gives me "This site can't be reached" problem...
I have Samsung S6 with latest original stock rom (Nougat)
Any idea how can I test where is the problem with mobile internet connection?
EDIT:
It seams that I've fixed it by changing to 3G network and tested and it worked, then I've turned it back to LTE and it worked so now everything works.
Strange... never experienced before that some part of OS stops working and needs restart
