My phone will go from 4G to 3G randomly. When I go into APN it's says Verizon Internet isn't check and checking it does nothing. The only fix I've found to keep APN checked is switching network mode from Global to LTE/CDMA or LTE/GMS/UMTS. Is there a way to keep Verizon Internet checking without having to switch network modes every time?

[Q] Unselect "Use only 2g networks" causes phone to loss connection to network
Since Monday my Galaxy S2 can't use 3g networks anymore.
It only connects to my carrier if "Use only 2g networks" option is selected, otherwise it won't give me the possibility to make calls.
Anyone has a clue about what should be ruining the radio communication?
Is there a way to try to "reset" the carrier configs to the default?
I mean, I hadn't change a thing but on Monday my carrier had some signal issues in my area and I think this could be the reason of my phone's confusion.
More than likely carrier issues.
Please contact your provider to see when the work / fault will be completed.
Please update me with your progress xd, who is the carrier by the way?
fkofilee,
But if the phone can't connect to 3g, it should still connect to 2g networks, right?
I mean, unchecking the option should not make the phone lose signal, because 3g would be only another way to reach the carrier.
I'll try with a SIM card from another carrier to double check.
The carrier ir OI, I'm at Campinas-São Paulo-Brasil.
Unchecking the option will disconnect the phone signal very briefly.
Please ask your carrier tech team to give you carrier APNs info.
That way you can be sure the info your getting is correct.
Also check your APN settings...
All of sudden everything is back to normality.
Surely it was carrier's fault.
Thanks for the answers!
I have an LG Optimus F3Q (I'm a keyboard person) on T-Mobile. Rooted, stock. I've noticed that my wife and I will sometimes be in the same place and she with her un-rooted LG phone gets good 4G/LTE signal while I'm on 2G. I went to the T-Mobile store (did not tell them I was rooted, they didn't ask) and they gave me a new sim. That seemed to work ... for about 30 minutes. Then I got booted off 4G/LTE again. So I went back. They messed around with APN settings and stuff, still no permanent fix. But what I have noticed since doing that and learning a little bit about the network settings menu is I can manually get myself back on 4G/LTE by going into network settings>mobile networks>network mode and disabling, then re-enabling, GSM/WCDMA/LTE auto. (There is no "LTE only" mode for me to select.)
I printed out a logcat dump shortly after doing that successfully, but I know nothing about reading those logs.
Just for kicks I've tried adding an APN using epc.tmobile.com instead of fast.t-mobile.com but that one won't even connect me to the internet; perhaps I am doing something wrong in setting it up.
Anyone have any ideas here? I'd prefer not to have to go through several menus every time I want decent data service.

Just a piece of additional info: I've now noticed that I seem to get kicked off 4G when I make a phone call. So it seems like the phone is having some problem reinitiating its connection with the 4G data network ... ?
Guys i am having a problem finding the apn options on my sprint lg, The phone is unlocked for any sim, but im trying to get my 3g to work on this phone but is this option even Available?
It is under Settings / More / Mobile Networks
Then choose Network Mode
I guess if you just select CDMA, you will be forced into 3g only.
Hello. I have an SM-G925F which I bought from Telekom Macedonia and I am still using my number from there also but I am currently in the US and would like to use it on T-Mobile USA.
I know that the device supports all the same bands as the SM-G925T model.
The problem I am having is that when my phone is set to LTE/WCDMA/GSM in the Network Mode settings, I do not have any data connection at all, only when I make a call, I start to get a data connection but only 3G/H+. If I switch my setting to WCDMA/GSM, then I get a data connection at all times like normal but it still is only 3G/H+. I have tried two different APNs and different settings in the APN but I still cannot get a data connection at all times on the LTE/WCDMA/GSM setting and I cannot get LTE/4G at all.
After contacting T-Mobile, all they came up with is to try to have the same software reinstalled on my phone. Does anyone have any experience with this and can anyone help me?
Anyone?
Call Tmobile and have them input your phone's IMEI in their system. Ask for the APN settings as well. I am on the same boat and one call to ATT got me from H to 4G. Your phone will just show 4G, not LTE but you will get LTE speeds regardless.
I tried doing that too. I called T-Mobile a few times and they confirmed my IMEI number being on the account but still no luck. It's really weird..sometimes I get 3G/H+ on the "LTE/WCDMA/GSM (auto connect)" network mode setting on the phone but most of the time, I get NO DATA connection at all..only the signal bars.
Any Update
Did you finally figure it out? Is LTE working now?
I have a SCH-i605 on Straight Talk network using Verizon towers. It's rooted and running Bean's rom. For the past month or so, I cannot use internet with WiFi turned off or out of range. It's offline. In settings data is turned on. Airplane mode is not. Yet when I go to about phone/status/Mobile network state, it says disconnected whether WiFi is on or not. Straight Talk tech had me change APN settings which didn't help, then said it has to be the sim card. It's the same with the new sim card. Does anyone know what's causing this?
