No 3g signal

I'm on bamf soab 1.03 and I dont think anyone else is habing this problem but I'm wondering if anyone knows how to fix this issue. When I get 4g signal the phone will use it but won't use 3g. It drops out of 4g and then just stays without data. So basically its only using 4g or else its just not connecting to 3g. There is no data problem in my area because people I live with are getting 3g just fine....any ideas?

Menu > Settings > Wireless & Networks > Radio Info > Change LTE only to CDMA/LTE mode
if you don't have the radio info option there, download LTE toggle from the market and do the last step.

heh. i tried out the new 1.03 and market just kept crashing on me(even after force stopping/clearing data) and uninstalling updates. so i just thought "to hell with it" and switched back over to shiftao3p

No such setting as LTE only. And my phone has always been on LTE/cdma so its not that I already checked that. I'm not a noob user.

do you have EHRPD on under modem settings in ##778? It should be. Past that I sometimes reset if it has issues locking on to one and that will resolve. That's all for my ideas, though I'm still on SOAB 1.02

This is what i was going to suggest. Here's some information that might be helpful. I've found that with the network testing and stuff the past few weeks in my area, sometimes revision a enabled is better, sometimes eHRDP works better. Try switching revision A and see what it does.
Try dialing ##778# on your phone, hit call if you need to.
Choose edit mode
Password is 000000 (six zeros)
Choose modem settings, go down to revision A, and change from e HRDP to "enabled"
Press menu and commit modifications, phone will reboot.
After it settles you may need to go to *#*#4636#*#* and choose phone info then change your preferred network settings to get a solid signal.

I was messing with it last night and seems that the issue is fixed if it happens again ill follow those steps. I'm a pretty advanced user but I'm not so familiar with those settings so thanks for the help

I'm running a version of 2.11.605.3, de-bloated and rooted.
I lost 3G on October 21st. I would either get 4G, or nothing. On occassion, I would get 1x. Selecting CDMA only gives me NO data
If I change the REV-A option under the ##778# menu from EHRPD to enabled, the 3G comes back and the toggling between 3G and 4G works fine.
Switch back to EHRPD and 3G goes away. Seems like the problem is with EHRPD. I don't know why all of a sudden it stopped working correctly and I don't have enough tech skills to identify the possible cause.

VZW has had trouble with their Data network the last two weeks, could be a VZW problem. I have not had any 3G problems on my phone and I am running SoaB v1.03 on my phone.

[Q] Rogers APN Settings/CM7 Data Switching

I am having the data switching problem (stays in edge - wont switch to 3g/4g) on my Infuse when I install CM7. I have seen the 1 APN suggestion to fix this issues with AT&T but was wondering if there is a similar solution for Rogers.
as a work around I tried switching my preferred networks from WCDMA preferred to WCDMA only (i live in Toronto - so no issues having access to 3g/4g network at all times) but it reverts back to preferred, data switches back down and gets stuck in edge.

I am having the same issue. All I am getting is edge.
I have a nexus one though.
It only just started though. Probably within the 2 or 3 days..
Not sure what's changed

Same here.
It only runs on Edge. If I put my N1 on 3g, it works intermittently. Only when it wants to, and even though it shows it as being connected, it is not, as text messages come in hours later, and calls go straight to voicemail without showing anything on the phone .
I checked the APN settings, called Rogers, they confirmed all my settings were correct, but still, nothing.

[Q] Strange network connection issues

Hello fellow S3ers! I am David and I am new here.
I seem to be having a strange problem with my data network connection: My S3 is with Verizon and I have had it for several month now.
This morning everything was working fine down in FL and I hopped on a plane, set my phone to airplane mode, and returned to Philadelphia. After landing and disabling airplane mode, my phone refused to connect to any sort of data network - no 4G, 3G, or 1x. Calling and txting works fine.
I have been searching for a while now with no success. But here is the strange thing: I went into About Phone > Software Update, and clicked "Check now." Low and behold, the 4G icon flashed on and downloaded the latest update! (Which was over 140mb).
The phone updated and restarted, and now it says Software up to date. I saw the 4G icon flash on for a moment after the initial update restart, and then it flashed off. I went into software update again, and clicking Check Now caused the 4G icon to turn on again! It immediately turned off again, however. I was able to repeat this cycle several times, but now the Check now button does not turn the 4G back on at all - even for a moment as it did 10 minutes ago.
Any ideas how to solve this issue or what is going on?
Please let me know if I can provide you with any additional settings or details, but here are some details that may be relevant:
Mobile data: checked.
Network Mode: Global
APNs: None checked, EHRPD and LTE - Verison Internet are white, the rest are grayed out.
Mobile network type: LTE:14
Service State: In Service
Mobile network state: Disconnected
I appreciate your time.

I got the same issue, was working yesterday but today nothing. If I force it to cdma only I can get 3g data but it didn't stick around very long either...

northeast is having data connectivity issues at the moment- I called in and thats what support told me so most likely its the network right now and not your phone with the issue

Thanks for the quick replies Neo and Chewwy.
Good news, 3G is now up on my device and it appears to be stable for the moment. No 4G yet, but I do have one more question just to make sure I didn't accidentally change something when I was troubleshooting it.
Network mode should be set to Global?
Should a specific APN be selected? Currently, both EHRPD - Verizon Internet, and LTE - Verizon Internet are white and selectable, however none seem to be checked with the little green dot. The rest are still grayed out. Is this normal, or should I select one?
Interesting to hear about the N.E. network issues. I suppose that makes me feel better lol.

Many people have posted issues with LTE where their cellular signal was fine for "2G" functions like calls and texts.
I'm having the opposite problem. After leaving airplane mode (landing at an airport today), I have a "No Service" message in the status bar drop down (notification tray), and the Settings>Network information page shows "Not Registered." However, I do have an IMEI (see details below). However, LTE data works perfectly fine.
I've obviously tried changing the settings in Settings>Mobile Data (preferred network to Global / LTE / LTE/legacy 3GPP mode) connection type global/auto/LTE/etc), to no avail. If LTE is connected it works flawlessly, but I cannot make calls or texts, and show not registered on the network. Data roaming is set to deny, but even allowing roaming does not change the situation.
Before this happened, I HAD gone through all the XTended Settings, and even 'looked' at (but did NOT change) some advanced settings pages, including the 'hidden' HTC network info page ( *#*#4636#*#* ). Again, however, I didn't change anything -- unless by accident?!
Does this sound familiar to anyone? Anyone know if I may have inadvertently changed something and can change it back (a setting that would persist in the hardware through NANDROID restores and factory resets...). Or, any other advice to restore the cellular service connection to normal?
I've tried a full NANDROID restore (multiple times) to a working copy, and a factory reset. I have limited access to a PC since I'm traveling, so re-flashing the VZW firmware or stock recovery or lollipop/verizon RUU would be challenging.
I did spend a good 45 minutes (at a library, my only PC access!) searching the forums and web, but to no avail.
Settings information:
OPperator Name: Verizon
Signal Strength -114 (I've had better but still have the same issues)
Mobile Network type: LTE
Service state: In service
IMS service state: Not Registered
Roaming: Not Roaming
Phone Identity page:
IMEI shows up (15-digit number...how can I verify I didn't mess this up?)
Phone Number is correct
IP Address: 100.66..... (looks good)
Any help is GREATLY appreciated!

Same here
I'm having the same issue. When i try to make a call my LTE bars drop to nothing and it says call failed no network available. Any ideas or help would be nice. I was using venom rom as well. I'm currently trying to flash the newest RRU to see if that resets things. I'm wondering if it somehow my sim card. I took it from my droid turbo. I've made sure to turn off advanced calling on my VZW account though.

I had this same issue, running from ruu then rooted. I didn't noticed until I started seeing voice mail notifications but never heard the phone ring. When I tried to dial out I got the immediate call lost message. I couldn't figure what was causing it so I just did a reset. I made sure not to restore any systems data from prior to the Lollipop upgrade. At this point everything is working, the only thing I haven't installed yet is the xposed framework and sense 6 toolbox.

What kind of reset did you do? I know my issue is slightly different, but I did a full RUU-flash yesterday (latest lollipop version) and still no luck. Unfortunately I'm out of the country now and access to a computer is limited, and I don't even have a SIM card yet to check if cellular service would work anyway.
I do intend to do a flash of the stock recovery and radios once I have the time and access, but that may be a while...
Still, I'll keep checking this thread to see if anyone posts any other options

Just go into settings and to Backup & Reset , this will return your phone to a fresh install and remove all non bundled apps.
Before doing the reset try going into Settings then Call then change Preferred Network to Global, or toggle from LTE then back to Global.

Carrier Settings and phone settiings

I've been using Three on my OPO for a couple of weeks now after I transferred from Giffgaff.
I am trying to avoid speaking to the support at three as they are notoriously bad. I've tried emailing them twice about settings after I searched everywhere for APN settings and advice. Eventually I managed to get a basic APN from a post on here along with instructions on how to change the preferred network type. However I am unsure I have covered everything and I have been having issues with the reception dropping out.
When it does drop out it keeps telling me there is no network (giffgaff) even though I think I've got it set up for 3, which is confusing me.
Other than the APN and selecting the network, is there a setting I've missed somewhere?

I'm still having issues with my phone dropping signal. I don't know if it is three or the phone. Is there any way to check this?
While sitting at my desk at work, I go from having H+ or LTE to having nothing with the "emergency calls only" notification.
Can anyone help?
