The phone will automatically select the most effective data connection so you can't really help it i'm afraid :/

How to receive MMS on AT&T without a data plan?

I have a HD2 on the AT&T network without a data plan but have unlimited messaging plan so it allows me to use the AT&T network free for messaging. I have my wireless data turned off through the settings so that it does not connect to the network.
I was wondering if there is some way to have the data turned off all the time but automatically turned on when trying to send/receive MMS messages? Is there an app or widget or specific settings that I could use?
I'm using mdeejay Froyo HD 3.7 ROM with hastarin 7.7 kernel.

I have t mobile but usually have data off...when I get a mms, it'll have the download option...i then turn on data, retrieve the mms, disable data...that's how it work on my bangster...good luck

Yeah this is what I do too but I was wondering if there is a way to automate the process so you don't have to manually turn it on/off.

I have T-mobile but the way I do it is go to Wireless & Networks, scroll down and where it says something about Mobile Networks connect to internet, Un-check that, that disables your phone from using cellphone data to access internet where wi-fi is not available or when an accident happens

Yeah but this also blocks MMS..I want to keep MMS.

If you data is turned off you wobt be able to send ir receive mms. Mms are sent through data.

Here's what you do:
OPTION A:
Turn on airplane mode and turn it off and see if mobile network works?
OPTION B:
Turn on wifi and turn off mobile data and then turn off wifi and then after you turned off wifi you can turn on mobile data and it should work.
If I helped you please press the thanks button.

still no data
Thanks for reply. Turning on and off airplane mode didn't help. When turning on mobile networks it stuck to turning on but nothing happens. Is there any setup should be done?. I was able to use data connection in hyberdroid cm7 without any setup.

This appears more to be around APN settings.
Settings > Wireless and Networks > Mobile Networks > Access Point Names
Make sure what is selected is your provider. Also, Google for your provider's specific APN settings and ensure they are all the same.
Edit: Also ensure "Data Enabled" is ticked on the Mobile Networks screen.

thanks a lot ... this was the problem.

WiFi and 4G simultaneously

I keep noticing that while I'm on my home WiFi that my 4G data keeps popping on and off, what can I use to figure out what the cause/app is?
It seems to be affecting my battery as well as I'm getting some pretty serious battery drain.

For lollipop. You probably have "data network preferred" set. Also, under settings/WiFi/advanced there is a check box for switching to network if WiFi signal is weak. Want to unchecked that.

I don't have that option checked though. Also I can't find where I would select data network preferred.

Have you checked the "Smart network switch" which would automatically switch between WLAN and mobile network when some network is poor?
The option is at Settings - WLAN - Smart network switch.
Maybe you can limit or disable mobile data when you are using wifi at home:
Settings - Data usage - Set mobile data limit
Settings - Data usage - Menu button - Restrict background data

I do have that set to off. I think it's some rogue app on my phone.

Mobile Data and WiFi

How does the phone prioritize between Wifi and Mobile Data? Say you have both Wifi and Mobile Data turned on does the phone use Wifi if you have an active connection? Can I leave Mobile Data turned on and not worry about using up my data if connected to Wifi?
Noticed that I have no Mobile Data toggle in the quick toggle menu. Since I am on a limited Data plan I like to toggle it on and off. I did find the toggle in settings but that is annoying to get to.
I decided to try out Tasker to make a task when at these cell towers turn on Wifi and turn of Data. Turns out with Tasker you need to be root to turn off Mobile Data.

If you leave your data on, you will have battery drain and also more data tracking taking from you as well.
You don't need both on.

Any recommendations on being able to toggle Mobile Data on/off with out having to go into settings every time?

There are multiple settings you can use: Like WiFi preferred, or you can even prevent apps from using particular networks you specify, or block particular programs from network access all together. It may take some time in experimenting but there are many options to choose from.

Hello , i have similar problem, when is connected to wifi , dont disconect data, i see all trafic go to wifi, but the battery drain fast, and if i dont disconnect data manually charge is slow too!
I try many thing,reset network settings, wipe cache, include factory reset, and re flash the original firmware, but the problem persist, i was call samsung support and say, we have to repair it, but i buy the phone in usa and live in spain
Any solution for that?
Thanks in advance

It will always use WiFi if you're connected to WiFi. Battery life really shouldn't change at all since no mobile data is flowing through that connection, and even with mobile data off you're still connected to LTE, it just won't use it for data.
Go to the WiFi settings and make sure smart network switch it off, otherwise it will disconnect from weak WiFi and use data.

Yes smart network is off
Download booster off
On developer option, keep mobile data turned on is off too
I just factory reset again, with out any update or software , on the first reboot this issue happen again
Make me crazy!
Thanks in advance

By default your phone will use WiFi for data whenever WiFi is connected. You shouldn't have to manually disconnect mobile data.
If you want to be doubly sure, have your mobile data on and at the same time connect to a WiFi that is not connected to the internet. You will find that you will not be able to browse the internet, update any apps or do pretty much anything that requires the internet.

Yes i can manually disconnect data when is wifi connected
But is miss it, battery drain so fast

I see from your pic that mobile data icon is showing at the same time as your WiFi.
Perhaps you may want to reset your network settings.
You do this by: settings > general managment > reset > reset network settings
Edit:
Never mind, i see that you've tried this already a couple of post above.

I already do , also i do wipe data and cache, factory reset, and flash original firmware , and problem persist!
