WIFI and Mobile Data Problem - Galaxy S III Q&A, Help & Troubleshooting

I have this problem.
When I connect for a while my S3 to wifi, then when I turn off the wifi my phone does not return to connect to mobile data.
I need to turn on and then off the Flight Mode for resolving.
Any tips or someone with the same problem ?
Thanks

Yeah I know, the same exact thing happens to me to.

[Q] How to use mobile data even though wifi is not turned off?

Hi everyone,
My phone's wifi module (also bluetooth) was broken and cannot be used.
It can be turned on, but does not work. and cannot be turned off then.
It reports "error" status.
Unless I restore factory setting or new flash it, no other way to fix this.
Thus, I cannot use mobile data (3g, Edge, HSDPA etc) as internet connection,
because the system would use wifi instead of mobile service if wifi is not off.
Do you know my problem from my discription?
It's some complex...
What I want is any solution from the following two:
1) How to turn off wifi? The module is broken, it reports error when I turn off it from the settings menu.
2) How to enable mobile data thouth wifi is not off?
I guess some operation from the console (command line) is needed to do this.
If I get any one solution above, I can solve my problem.
Thank you very much for reading my post.
Wish you good luck.

even if the wifi is still on you should still be able to use mobile data since the wifi cannot connect to any wifi points.
how did you break it? maybe that is messing up the mobile data part aswel stopping it from connecting

I almost forgot the post.
The module that controls wifi and bluetooth does not work because of I knocked down a bottle of water that aside the phone.
Now I only have to never enable wifi at any time.

Hey i did some research apparently the HUAWEI Ultra Stick E1220 goes to sleep when the tablet enters stand by mode.This same modem is also used in laptops and has the same problem when the laptops go into sleep mode.Unlike the wifi modem which works in sleep mode this modem turns off as a power saver setting .Hope there is some update to fix this but i doubt

[Q] Mobile data not working after WiFi signal lost

Hi all,
bought for my wife Padfone S but when she leaves home WiFi, data does not automatically turn on.
If I turn off WiFi manually, data gets connected automatically, but if she just leave the range of WiFi with WiFi still on, but out of reach, the phone doesn't connect to 3G even if I'll turn WiFi off & on, data on & off - only what helps is restart of the phone - then connects to the mobile data without problem.
Phone is new, not rooted, stock ROM.
Shall I send to service?
Thanks for any tips.

My girlfriend and i both have this phone, her's had the same problem in one of the first software versions. Then a restart would help, but after the latest updates this problem doesn't occur anymore.

What software version you have?
I've bought the phone in East Asia and can't update any more. But played with the APN settings & actually it helped - the default settings was strange and now it works.

About data connection after WiFi off

Hi all, I have encounter this problem since 2 month ago.
There's a way to reproduce it:
Turn WiFi on and you have to connect to any router, then you can keep data connection on.
After 30 min to 1 hour, turn off WiFi. Now data connection should working, but in my case, I can't.
Thought the data connection is enabled, it just unable to connect to the server...
I have to enter "test mode" to turn off Wireless connection and turn it on again to fix it.
Or to turn on/off airplane mode to fix this issue.
However, I've seen no one complain it here.
Is there anyone have this issue and how to solve it?
P.S I've tried all the ROM and Modem from v24p37 to v24p50
