Personally, I had this issue the first time i flashed test4. No data without wifi, and voice bars were very laggy. I switched back to my stock rom for a day, and when i returned to play with it that night (reflash from .zip, not restore from backup), no more problems. The initial transition to 4g from 3g seems to take a bit longer than on the stock rom, but once it is up, everything is smooth. Not constructive, I know, but it is a data point.

ok thanks. but which is the link to test 4. i have a feeling i installed the wrong one. can u send me link if u can? thanks

Check the device thread on cm7 pre alpha links are at end. You want the one with a three which is actually the fourth one.
Here is how to get signal.
1. Goto network settings, scroll down to network type, select the cdma/edvo option.
2. Wait until green 3g. If it doesn't pop up repeate step 1
3. Once green, change setting to cdma+lte/auto and hit your screen off button. Don't touch phone for 5 minutes.
I'm not sure turning screen of makes a difference but this is how I've repeatedly done it.
I have found that if you loose 4g you can loose all data. Just repeate above. It seems to work for about 10 hours then a reboot is required.

tonyagee is correct. This worked for me when I originally had your issue.

thanks guys but this doesnt work for me. ive tried it with stock and leaked radio.

I too have CM7 and have issues with data/3g. I'm not in a 4g area so I can't speak for LTE. What I noticed is that if I'm connected to a wifi-network and move out of range. My phone has a hard time getting into 3g and vice versa. If I go from 3g to wifi. Same thing. It appears that this is a bug but I'd like to find the buglist so I can confirm. I have, however, been able to get around this issue by rebooting. A good indicator of data transfer is when the wifi icon or 3g icon is green and in the case of a 3g icon, the arrows are flashing. If they are white, you are connected, but you aren't getting any data.

Not sure if this answers your question but I would try the wififix that Imoseyon made (link is in the CM thread somewhere). I enabled 3g, then rebooted into recovery and flashed the wififix file. Once the phone rebooted, I was able to move between 3g and wifi without issue as long as 3g was enabled first.

After I flashed CM7, Data/3G doesn't work

Just got an atrix, unlocked bootloader, rooted, did all that...
H+ and 3G were working fine with stock rom. I then flashed to CM7 and no data... There's no H+ or 3G icon, and internet doesn't work.
Any ideas??
Check your apn settings.
Checked the apn settings, everything was fine there.
Try downloading and flashing Other Radios via CWM. There's a thread in the General section with tons of radios in it. Choose the ones for you and see if it solves thir problem.

Just updated from 0.91 to 1.77.36 radio and still have the same problem.
Tried reflashing CM7 again, doing several wipes before and after, didn't help.
One thing I noticed is when I delete all APNs, and then create a new one using the Straight Talk APN or some of the ATT ones, is that as soon as I save the changed I get either a H+ icon or a 3G icon (depending on the APN) at the top of the screen, but it stays there only like 3 seconds and then goes away. So it's not enough time for me to even check with a browser if there is a connection.

[Q] WiFi & Network Signals turn blue when connected to Google Servers.

Hello,
I was wondering if there was a How-To thread on doing this? Or could someone help me do this? I couldn't find any from my search's.
Current ROM: δ-HyperDroid-Androidmeda-v3.0 (with petsaj's surgeon)
This feature is already there in the Hyperdroid + petsaj surgeon combo I use. The reason I ask on a how-to for this is because, for some reason, custom ROM's that have this particular feature are the only one's I can use to get 3g data connectivity. Otherwise, I always get this irritating "Refreshing SIM data" pop up, which eats up battery, and heats up the back of the phone.
I'm still not a 100% on whether this would be the actual reason, or whether its a an issue with my carrier, but i want to give it a try so i can know for certain.
Any help would be greatly appreciated.
Arjun.
Im on Revolution ROM, and it has this feature. Try it c:

Thanks. But I'd like to find out how to do it myself; to test and see if this is whats causing issues with 3g data connectivity for me. I think even Simple & Clean v2.x has this, and so do a few others.
But I don't think MIUI ROM's have this (not sure about this again - from the MIUI's I've tried, doesn't seem like they do).
My main concern has to do with 3g.
Thanks again.
Sorry to bump this. I didn't want to create another thread with the same question.
Hopefully someone from Hyperdroid would see this.
It's as simple as changing some png's... Download my surgeon, navigate to /vrtheme/SystemUI.apk and see which ones are blue and which ones are grey.
Thanks petsasj.
Will try it once I'm back from work.

Ok. I was just having a look at the pngs in the Androidmeda 5.2.xx and the pngs in /vrtheme/SystemUI.apk (of your surgeon). Only difference I see is the colours are green in the base while they blue in the surgeon.
I dont think this could be the coz of my 3g issues.
Petsasj: any idea why I am able to use 3g only after flashing your surgeon? Like i said before, if i flash the base ROM (or any ROM for that matter), either of two things will happen:
1. In GSM/WCDMA mode, it'll search for my 3G network -> the 3G icon shows up, and instantly disappears. I am still connected to my 3G network, but there is no data connection. On checking the "Status" in Settings it shows up as Mobile Network->Connecting.
2. In GSM/WCDMA mode, it'll search and connect to my 3G network -> there wont be a 3G data connection. "Status" in Settings says Disconnected.
For both the above instances, this "Refreshing SIM data" pop-up keeps on coming. The phone heats up at the back - battery goes down the drain! Very annoying. 2g works though (with data connectivity).
But if I flash your surgeon (and only your surgeon btw, the other surgeons dont help me with this issue ), everything works! 3G, 2G, switching between the two... !
Would u have any idea as to whats causing this??

Turl CM9 data connectivity issues

Ok, first off I've searched many of the data connection issue threads out there but nothing seems to apply to my situation.
I'm having a problem where my data will disconnect whenever i receive/make a call and/or send/receive a text message. About 1-2min after the call has ended data will reconnect, if I toggle airplane mode data will reconnect a bit quicker.
I'm using a Bell Atrix, unlocked running Turl's CM9 from the below thread
http://forum.xda-developers.com/showthread.php?t=1500535
I've had the phone for a year running the stock 2.2 then 2.3.4 then 2.3.6 and never had any problems until I unlocked the bootloader and installed CM9 a couple days ago.

You sure you're not in an EDGE/GPRS area? You can only have data during phone calls on 3G/HSPA+.
Edit: To verify this, go to Settings > About phone > Status and look at what it says for Mobile Network Type.

System settings/about phone/status/Mobile network type is :"HSPA:11"
I'm in a HSPA+ area, same location I've been using the phone since I bought it a year ago which is in the city core
ok, after a bit more trial and error I haven't been able to solve the problem but I have been able to narrow it down. As it turns out when GPS activates my connection will disconnect for the 1-2min as per above.
My workaround was just to disable GPS for the time being, but this isn't exactly a solution, if anyone has any advise it would be very much appreciated.

Remove multiple APNs. This happened with my old Desire Z. Whenever the GPS is on, data disconnects. Deleting unused APNs fixed this.
hmm, I've never deleted an APN before, if I do this will the network automatically reselect ones for me?
Don't delete everything, just delete what's not needed. The APN that's in use has a selected radiobutton at the right side. Leave that and the MMS one alone, delete the others.
I just deleted one of my two apns, then tested internet and a voice call which both still work, I turned GPS on and opened maps, I get the gps icon on the notification bar but it isn't blinking(also my network connection reset again), then I tried GPS test and again the gps icon at the top isn't blinking like it used to(it has the icon but it's hollow, i.e. no dot on the inside of it blinking) though my network connection didnt' reset this time at least.
I'm about ready to just chalk this up to CM9 on the Atrix just not working right because its unofficial and lacking proper drivers.
GPS icon in status bar does not blink when searching in ICS. You get a blank crosshair when it's searching for a signal, and a filled crosshair once it gets a lock.

ok so I tried turning gps on and running gps test, I let it go for 20min and it didn't pick up a single satellite(this is outside)
Try clearing agps data.

Thanks for the advise, I downloaded "GPS Status & Toolbox" from the market and used it to clear my A-GPS data, this seems to have solved the problem of my network disconnecting, however I'm still unable to get any satellites to show up in GPS test(yes GPS is turned on).
Any thoughts?

4G Issues on CyanogenMod 10.2

I am new to root and ROMs so perhaps I overlooked a setting.
I just rooted my phone and flashed CM 10.2 a few days ago and I cannot get 4G anymore. I can only get 3G. I have tried a few fixes like dialing *#*#4636#*#* and adjusting the APN settings but nothing worked. I have the LTE button ON and I am wondering if I am still getting 4G because I have LTE on and it's just showing 3G. But I don't think that's the case.
Any help or tips would be greatly appreciated!

reflash stock rom. make sure you have 4g. flash the vram3c radio then flash cm10.2 rom. you should have no problems with 4g after that.
I will try that. Thanks!

I tried flashing the radio and CM again and sometimes 4G comes up for a few minutes and goes back to 1X. This happens where I have gotten 4G before. Maybe the radio isn't as strong?

My personal experience, living in a fringe signal area, is that AOSP roms just don't have as strong a signal as TW roms (it presumably has to do with how the RIL had to be hacked/reverse-engineered to work for AOSP). I would prefer running AOSP, but unfortunately in my experience on my S3 and Note2, where I am located on the fringe of full 4G coverage areas, I have the same issues as you: on TW, full, fast, 4G; on AOSP, very obviously slow 3G or 1X.
Edit to say I've only tried 4.2.2 ROMs, haven't tried the 4.3 ones yet, so if I'm handing out wrong/outdated info, I'd love to be corrected.
I am now running a stock 4.1.2 ROM and still cannot get 4G. I now for some reason can't even dial *#*#4636#*#*. When I try it just says "Welcome to Verizon Wireless, this call cannot be completed as dialed." Anyway to get that number to work so I can check my networks again?

Try going into settings and factory reset phone now. If that doesnt work, reboot into stock recovery and factory reset from there and reboot. That seems to restore signal for those of us that got stuck in roaming mode from the Carbon thread. Might help your problem too
So I decided to re-flash CyanogenMod 10.1, adjusted the APN settings again, and I have 2 bars of 4G right now. Usually 4G will flash a couple times and change to 3G, but it is staying 4G, so hopefully it stays that way!
Well it stayed 4G for a bit until I turned WiFi on. The moment I turned it on, my 4G went to 3G. I turned WiFi off and I still have 3G. Anyone know what would cause this?
EDIT: My network type shows eHRPD with 3G, where as when I had 4G (before I turned my WiFi on) it showed LTE. If this helps any.

Where do you live, i know the mid Circle drive all the way over across platted to the airport are just dead zones. I lived on Verde drive and rarely had good signal, then when i moved up circle behind the bowling alley i never had a good signal. Just something about the antennae in that area. T-mo is a complete bust in that area. But i'm sure you probably all the way over on the Nevada side completely making what i said irrelevant.

Do a search on towers in your areas. If I remember correctly the closest tower to you in right by the interstate by the new (now not so new) MCD's in Security. That tower had alot of problems in the area past the Olympics complex all the way back to Peterson because of the radio towers for the Jets. I have been gone for almost 3 yrs so don't take what i say as truth tho. Just how it was when i was there.

I've had that problem before. .I used a mod like this.
This mod is from DroidXcon, Try this and hopefully it will work. (make a backup of your buld.prop first)
Instructions:
1)Go to market install BuildProp Editor
2)Once installed find and open Build Prop Editor
3)Hit the menu button and select Edit
4)Scroll to the bottom of screen and add the following lines
Code:
ril.sales_code=LOL
ro.csc.sales_code=LOL
5)Hit the save button at the top right hand corner of the screen(looks like a disk)
6)Once this is done saving restart the phone
7)After restarting go to Settings>More Settings>Mobile Networks>Access Point Names>Menu Button>+ New APN
8)Add desired carriers APN info, when finished hit menu button and save
9)Power down and change to your desired SIM card if you hadn't already done so
10)Power back on and go to Settings>More Settings>Mobile Networks> Access Point Names (if done properly you should see the APN data you entered for your respective carrier).
11)Select the respective APN listing and then you should have working data

I tried this but having the same problem, so I decided to save the APN each time I edited an item, and every time I would change the MNC and save, it would not be on my APN list, and it would be blank again.
Bump... also having this issue. Trying CM 10.2 for the first time since August. It had Bluetooth issues back then, so I've been running Bean's ROM until yesterday. Can't get 4G serivce in what is absolutely a saturated 4G area...
Was able to fix the issue by wiping the phone completely (including internal storage!), installing Bean's ROM, doing a factory reset, then coming back.
FWIW I always wipe internal storage when going back and forth between 4.1 and 4.2+ roms, seems to alleviate any SD card issues that can arise from the changes to filesystem in 4.2.

[Q] Cyanogenmod 11 3g Connectivity Issue

Hey,
Just rooted and flashed CM 11 onto my HTC one and everything is working perfectly besides 3g. The only issue I have is that the 3g isn't working very well, if at all. Sometime I can get it going for a couple of seconds but that's often it. Sometimes it modulates between 3g and h before shutting off.
I checked the APN so I don't think that's the problem. Has anybody else had similar issues? Have any solutions? Do you think I'll just have to wait for the next nightly to come out and patch this over?
Thanks!
Still Nothing
I've tried cycling down to other versions. Most notably stable versions of both 10.2 and 10.1. Even in these stable versions 3g connectivity doesn't work. This leads me to suspect I'm missing a file. I noticed threads elsewhere in which people had to flash special files for the radio? Not sure if this has to with this.
Also something about S-Off. Could really use the help because right now 3g doesn't work in any version of CM.
You're saying you get H often but not 3g? Because that's how it is supposed to work

Nothing
Even when it goes to H it immediately shuts off. Nothing really sticks for more than a couple seconds (3g nor H).

access the phone’s test menu by dialing *#*#4636#*#* From there, tap Phone Information and you just need to change the “Preferred Network Type” and try and force the settings you want.
