Mobile Data Toggle in Notification Panel

I had a question about the Mobile Data Toggle that's in the notification panel. When I click it I thought only data was turned off, but calls cannot be made or received either. Is there any way to change this so that data is turned off but not calls?
Thanks.
Calls and texts are suppose to come through.

Data has nothing to do with phone calls or texts unless you are attaching something or trying to download something

Connect to 3G Only?

Is there a way to manually set to 3G only even with a 4G signal available?
There is an app in the market called phone info that will allow you to do this just set it to cdma(auto)

Why use an app? I can set this in the Phone Settings menu!
Not in an hd maxx you can't
And dialing *#*#4636#*#* ? This opens it on all Android normally.
Yes that works but it's a lot easier to do in settings if it were only there! I assume you have the non-HD model?
Yes that is correct, I use the menu but my 4G battery is surprising

Change imei back to tmobile

Okay. So I bought an unlocked g2x brand new from Amazon. Everything almost works as it should: calling,wifi,texting ....the thing is I cannot send or receive picture messaging.
I spent hours on the phone with T-Mobile (ironically bought an unlocked phone that was originally T-Mobile to use on T-Mobile network. Funny right?) and they say because the imei number is unlocked I am unable to do picture messaging without a data plan. I can't afford a data plan right now.
Anyways I'm hoping there is a way to change the imei number back to being T-Mobile specific. In other words: I want to lock my unlocked phone back to T-Mobile.
All I want is picture messaging. I shouldn't have to have a data plan to achieve this. Can anyone please help?

It shouldn't be your imei, it's your apn settings. Go to settings, wireless, network settings and make sure your apn is set for tmobile.
My phone is unlocked and I send pictures without a data plan. Just remember that you need to have mobile data enabled. It uses data technically, but it's incorporated with your texting plan.

You sir are a genius. That actually fixed my problem.
Now, I have data blocked on my phone so I shouldn't be able to use the data thing even if I tried. ...
I did activate that setting and upon successfully sending a text,the 4g logo does come up where my signal strength and battery are shown. Can you confirm this to be normal? I don't want any extra charges on my next bill....
Sent from my LG-P999 using xda app-developers app
Call them and make sure there's a data block on your phone. You won't get charged. And yes the 4G logo will show when sending an mms.

I spoke with the T Mobile representative. I believe her exact words were : Now you're not supposed to have multimedia messaging on an unlocked phone, But it's changing that setting give you the ability to do so then that is great.
Haha. But yeah she basically is telling me what you guys Are telling me I cannot thank you enough.

I can send mms. But I can't receive them.....any ideas?
Sent from my LG-P999 using xda app-developers app
Data turned on when downloading it? Edit your APN, make sure the APN is set to etc.tmobile.com, mmsc set to mms.msg.t-mobile.com/mms/wapenc, mac set to 310, mnc set to 260

Did you mean to put "Epc.tmobile. " on access point names?
Would I be asking to much for a little help navigating to those particular settings?
Thanks redmonke.
Sent from my LG-P999 using xda app-developers app
Ok after rereading, I see you said to edit my apn, which I assume is short for access point names. Should I edit the only one that is there which is "T-Mobile us, Epc.tmobile. com "
Or should I create a new one?
This is of course assuming that apn is access point names.
Sent from my LG-P999 using xda app-developers app
I did what you suggested, although I had to Create a new apn rather than edit the original because the original will not let me edit it....
After creating the new one, I suspect maybe a miss type in the settings. "Etc " is what I believe you said, but upon using that setting I could no longer send pics.
Once I changed it to "epc " I was able to do so.....
Anyways after creating the new apn as per your suggestion, I noticed that it was an exact mirror of my original apn.
But here's the kicker:
I was able to receive pics so long as my buddy selected to forward it rather than sending it directly (if that makes any sense) .
I then tried to have him compose a fresh message and select a pic to send....to no avail. I also had another friend attempt to do the same only to achieve the same results.
I am having zero issues sending pics.
And so long as data is enabled, I am able to do so.
Its the receiving pics that is giving me the issues.
I don't understand why I can receive forwarded pics....
If anyone can help I suppose I can send my cell number,(with great apprehension) ,via pm to someone who is willing to trouble shoot....

Hm so it looks like you are on the latest version. Did you do a factory reset when you got it?
Sent from my LG-P999 using xda app-developers app
No I didn't...would that somehow lock my phone to a specific carrier?
Sent from my LG-P999 using xda app-developers app
No but something might be messing up the mms.

Do you think if I installed a newer version of android I would be able to send and receive texts???
Or if I root it?
Sent from my LG-P999 using xda app-developers app
Root no, if a factory restore doesn't then I'd wipe data and install cyanogenmod and see if it works.

LTE and caller id

When I am on Lte and someone calls me it comes up unknown no matter who calls. When I'm on 3g it comes up correctly. Anyone else notice this?

It even comes up unknown if the person calling me is in my contacts list.

Sprint problems

I just switched over from att to sprint and got a sprint sim card activated for the phone, I can use lte data text and receive calls, but every time I try and make calls it disconnects and starts searching for network.
Anybody know how to fix this?
Sent from my Nexus 5 using xda app-developers app
Did you check your APNs?
It doesn't give that option in the settings
Sent from my Nexus 5 using xda app-developers app
Try changing the preferred network type.
Yeah I've tried that, it's weird because the data will work perfect fast 4g, and I can get calls send texts etc.
But the moment I try calling it disconnects and starts searching for service

Dial*#*#4636#*#*. Then make sure under phone is set to LTE/CDMA auto prl.
It was at to LTE cdma
Sent from my Nexus 5 using xda app-developers app
I'm assuming that you have tried the prl and profile updates. In the test mode (4636) switch to lte/gsm/cdma and then back to lte/cdma. Choose global instead of lte for the preferred network type.
Which radio? It might be a CSFB issue. You might try the .17.
Sent from my Nexus 5 using XDA Free mobile app
I tried switching to GSM and then back to cdma didn't work, I have update the prl and didn't Work
Any other suggestions?
