Wireless & networks>Mobile Networks>Network Mode is set to automatic, but when I go across the border from south to north, the radio doesn't change to pickup sprint.
In TJ, it's on Telcel GSM and should go back to Sprint CDMA when I come north.
It will, when i change to "Any CDMA" and then swith back to "automatic." But then of course I have to accept all the warnings and change the roaming settings again. EVERY FRIGGIN TIME.
It will automatically change TO Telcel from Sprint when I go south however.
What am I missing to make this work right?
Are you stock our on an ics ROM? Ics roms have it set to be home = sprint; automatic = roaming

stock, rooted only.

before rooting my phone under network mode I used to have the option to select WCDMA/HSDPA but after rooting it that option has changed to GSM/WCDMA, how to I fix this?
Unroot........
Naaaah, i have always had gsm/wcdma option, but phone is working in hsdpa mode according to speedtest.net. So it seems to be only a name difference.
i have the same problom my phone has no 3g or H signel anymore
try to enter the apn settings manually.
in the UK we always had GSM/WCDMA even if the phone was running in HSDPA, and since most of you root onto the generic UK firmware that is your answer.
Gsm/hspa is probably a operator specific branding. But its total nonsense , gsm/wcdma is the correct wording as wcdma is umts and hspa is a software specific upgrade which is not available on all towers in most networks.
But in order to use it at all WCDMA (umts) needs to be enabled

having messed up my phone yesterday installing themes/playing....i had to reflash, so after it all finnish i now get H signels fine and 3g in the house ..and yes i have rerooted.
So I installed cyanogentazz v8 the other day. I decided to check and make sure my phone was using the right radio band so I did the following:
Dialed *#*#4636#*#* > phone info and radio was set to wcdma. So I switched to cdma auto prl and then menu > select radio band. It forced close as it should. I turned the screen off for while, then I check again and it was set to gsm. I had not restarted the phone it anything like that. I switched back to cdma auto prl and turned the screen off again. A few minutes later it was set to wcdma.
Now my question is could the app toggle 2g be doing this? That's really the only thing I can of that would change the radio band. Any insight would be great.

I just changed the band and hit the back button and rebooted. I didn't do Menu > Change Radio Band. When I dialed back into the settings, it was still at prl cdma auto.
Not sure what wcdma is.. anyone know?
Checked again and it went back to wcdma. Something is changing my radio band...

Yes, Toggle 2G will reset the network type. However, new in version 0.0.8 I added an option to pick which network type to use for 2G and 3G modes. Just open the settings and set 3G to cdma auto prl

Thank you for your answer. And thank you for creating this awesome app. Saves me loads of battery without the hassle of turning data off manually every time I turn my screen off!!

I'm on CELB Froyo 2.1 and since changing my radio band from wcdma preferred (default on rom) to cdma auto (prl)(default on stock), my battery life has been crap!
Can someone explain this?
Thanks.
Im in a good 4g area and it randomly switches to 3G. Is there a way to make it stay?
You may not be in as good an area as you think. The signal strength meter is actually for 3g, even when using 4g.
Open the dialed and use *#*#4636#*#* and you can set to LTE only instead of LTE+CDMA auto + EvDo (can't remember exactly how it's worded.
You want to use the dropdown preferred network setting. Remember after switching, give it about 30 seconds to make the swap between changes.
That's a very handy dialer string everyone should know from memory.
If you want to disable the 4G radio so it's not searching for a signal if it doesn't exist in your area, go down to the preferred network and choose cdma auto prl.

There is a program in that market that will take you to the same place as that dialer string.
LTE ONOFF
I could never remember the string, and since I was going to need to switch to GSM networks in Europe I just used this. It works well. And the LTE only option is labeled is just LTE Only
So there is a setting burried down in Settings, More settings...Mobile Network. There are two options. CDMA and CDMA/LTE/EVDO. The CDMA option was selected stock. I have changed to the CDMA/LTE/EVDO option. Does this mean I will see/connect to LTE towers as they start lighting up in Atlanta-metro next week?
Or will I have to wait for some push update from Spring/Samsung that adds another connection type (e.g. Wifi, Bluetooth, etc...) to the mix?
The reason I care is that I don't want to root my phone until after I know it will work with LTE so I can ignore the sprint updates after that.
Help?
Hi, I am currently using the VZW Google Edition ROM 5.9 and have service and WiFi. My problem is it only connects to 3G, and not 4G. As advised, I have not gone into network settings, but I did open Phone Info and see that it is set to LTE/CDMA auto. Any reason I am not getting LTE?
Just a thought, but maybe you could check the APN settings and see if they are different than what you should have.

Thanks for the response. I am kind of new to this, where do I check the APN settings and how do I know what I should have? Thank you.
Do you have LTE coverage in your area? If so, can you use another phone/friend to double check if LTE is working? I only ask because we had LTE go out where we live.
Gir brings up a good point, I don't have 4G where I am (and probably won't for years!), but that may be simplest as long as they use the same network (although many carriers piggyback off the same network).
The APN settings should be under "Settings > More networks > Mobile networks > Access Point Names". On a stock ROM you have to get to the actual file through ADB, you should be able to see it if you have an aftermarket ROM. The settings for the APN will depend upon Verizon. Here is a good post with APN settings for Verizon, the first part is for Android.
Coverage could always be the issue as that has plagued me more times than not.
From the ROM thread:
Go into mobile network settings.
Verify that your CDMA subscription is set to RUIM and not NV.
For good measure go into the rest of the options and set it to CDMA/LTE, automatic, and allow data roaming.
Back out to your home screen.
Then go into Phone Info app.
Scroll to bottom and tap radio off.
Open the drop down list and select CDMA/LTE auto (PRL).
Turn the radio back on.
Reboot.
Upon reboot open Phone Info again.
Verify it is set to CDMA/LTE auto (PRL)
** you should have full service now * *
** if not * *
In Phone_Info(*#*#4636#*#*):
Try CDMA auto (PRL)
Then try CDMA/GSM/LTE
If those still don't work then your nv_data needs reset. The only way to do that is in the hidden menu dialer codes in a touchwiz-stocktype rom
If you destroy your nv_data and cannot get data back via the above you need to (stop screwing with your network settings)flash back to a TW ROM, enable hidden menu, and do a NV data reset via dialer code. After doing that make sure your phone is not in modem mode under diag dialer code. Until I update this section Google is your friend. And it is available information, verified. Your lack of searching skills doesn't mean pester my inbox...
I do have LTE in my area, as I had 4G before I loaded the rom. I do not have an APN menu under mobile networks. Do you think it could help to dial *228 option 2 to update roaming? Or possibly a new 4G sim card?
Anything about updating I would research first and be wary of... A new SIM card could help, but I'm assuming it is not the problem. Did you make a NANDROID before you changed ROMs? You could then go back and see it you still got 4G to make it evident if your SIM card is the problem.
FIXED
Just needed a new sim card. Thanks guys. I appear to be receiving signal bars with my LTE on the GPE rom as well.
