Try updating prl and profile. Then if you have a custom recovery, wipe cache and dalvik.

I never realized my problem was due to network issues. No new device was registering EVDO, my dealer & friends tried everything under the sun to get the data working. Finally I called up customer care and asked, they said it's because of network issue, will ok after a day or so. It did.

EVDO PPP Connection Error

I upgraded to the new DCD Beta 2.0 and when I try to connect to the mobile internet I get an error stating it cannot connect for an unknown reason. It also states Error Code: 11 - PPP Connection Error.
I am on Verizon and dialing #777, this still happens when I manually enter my username (ph#@vzw3g.com) and vzw password. I've tried a hard reset, but still the same issue.
Any ideas or does it look like a call to Verizon?
Ok, So I called Verizon and talked to the for a long time. They think it's a bad phone and I should try and get a warranty replacement.
I'm pretty sure there has to be a setting in the rom that I can change from when I originally had the Sprint ROM on there.
Any ideas?
I have Verizon also. I pay as you go so I normally do not connect with the data connection. So I put in your settings and had no problem connecting or surfing the web. I am also running the new rom. Hope this helps.
I think my main problem is that I installed the Sprint 3.16 "unofficial" rom onto my phone. When I went back to the Verizon rom I had to manually load a PRL to get back on the Verizon towers. Now I need to figure out what else to change to get Data Back.
Data/MMS OTA download resolved
Good news I got it fixed. I had to call Verizon. It's a problem on their network, something to do with the way the account is provisioned. This is an issue that shows up for folks that don't have an unlimited data plan and are only setup for pay as you go. I wish I could give you more detail about what to say but as usual with tech support it depends on who you talk to. I would just keep calling back until I got to the right person.
Data Connection Resolved
I also had a similar problem on the VZW network. Tried many setting changes last weekend to no avail, I needed to get a new A-key so I downgraded to 1.6.10 because of the 3.27 radio issues. The Data connection still didn't work, so I called and got a new A-key, then once that was working, chased the Data connection with a different tech support group, they tried the usual resets and programming. Finally, the tech guy exhausted his list and pushed the problem to network support, an hour or so later the data connection was working again. Network support called later to check to see if my problem was resolved, which it was. He said they had to reset the local switch, something about a hung data session.
I've on Sprint, and I've been having problems getting my data working again with the new 3.16 ROM. I called tech support, and after verifying all the settings, they looked for outage reports.. and found a global Sprint vision provisioning issue currently logged. We'll see if things improve in a few hours..

[Q] No Data connections via Phone in Android

Hi:
I am using AmeriCanAndroid AOSPHD2GB232CM7RC1|bkup2sdext234[KERNEL:AmCanAndroid r2.21] and just about everything works perfectly.
The only issue I seem to have is in Android, I cannot use the mobile phone to get internet. The Phone sends and receives call perfectly, but if I want to use Market or the browser, I get the error:
A NETWORK ERROR HAS OCCURED. rETRY OR cANCEL AND RETURN TO PREVIOUS SCREEN.
I think I have tried every combination of settings in the wireless section. Is anyone else having this issue?
Thanks in advance for your help!
Chaz
the only known temp(!) fix is to restart ur phone , given ur settings are correct it should work for a while .... have you been switching data on/off a few times? thats when it happens to me ....
be sure to report this problem to rom cooker so it gets fixed faster ...
When you say restart, do you mean restart android? I don't think I have ever been connected, unless there was WIFI in the area.
I use this ROM without these problems.
Try to check the apn and the DNS. Have a look at the faq.

everything works perfectly fine except for my data connection.
the only way i can use the internet is via wifi
No data connection
Yes I also has the same problem. Please let me know if you find a solution. Wifi works fine on my HD2 after flashing to Anroid 2.2 Bur no data connection through phone connection.
Thanks,

No Data connection
I am have the same problem on my phone also. Have the T-Mobile phone using the ATT system. Have tried several different roms and still cannot get a Data connection. A lot of us need some help please. If anyone can shed light on this, please let us know.
call t-mobile
i called t-mobile and told them, i could only connect to the internet via wifi. i pay for data and i cant connect unless its through wifi. DO NOT mention that you flashed your phone, put a different ROM or Android.
After doing this my internet started to work again
hopes this helps
do you set your APN?
May I ask what you told TMO?
I read in an older post that you may have to switch from smartphone data plan to android data plan to connect to the internet, does anyone have any idea about this??
I also am curious if my build is synonymous with failed data connection... as well as (not related item) battery sucking....???or any other know issues as I seem to misplaced the page I downloaded it from...

[Q] Mobile Data Not Working

Hey guys, So I recently restored my phone to the factory stock and I noticed that there was bars for signal on my notification bar, but nothing showing up about my data. I tried rebooting and restoring yet again to fix this, but I had no luck. However, I can still make calls and text people using my phone, it's just that the mobile data won't function properly. Is there a way to fix this or am I stuck with only using Wifi for the rest of my time with the phone?
Have you checked your apn? Settings-more networks-mobile networks-access port names. What apn is active?
Your APN settings has got messed up. Search on how to set it correctly and also what to set for your carrier

Thanks guys! Just got it working again by checking the APN of my parent's phone.

No Cellular Connection error after flasing cm-12.1-20150918-NIGHTLY-hlte

So after not really being into the custom rom game for awhile i decided last night to flash the following to my Sprint Note 3.
ROM: cm-12.1-20150918-NIGHTLY-hlte
GAPPS: open_gapps-arm-5.1-stock-20150918
when I left my house this morning I called my wife and it worked fine. Since then, however, any time I attempt to place a call I get a "No Cellular Connection" error. Data seems to work fine. In phone status it says it's connected to Sprint. It has an IP address. But the SIM status is Out of Service or something similar.
Any clue on WTF the issue could be? It would be awesome if I could place phone calls again.
Thanks!

I'm still fairly new to Sprint but IIRC Sprint doesn't have APN settings....
Is the phone running the latest bootloader and modem/baseband?
Old thread, but I'm having the same problem.
I just flashed CM 14.1 to my Note 3 (to freshen things up after all this time!) and now I have no cell service. I have successfully re-flashed the modem.bin to the phone from the stock ROM, but it did not fix the problem. Phone says Emergency calls only... and I have been getting emergency weather notifications, but I cannot place or receive a call.
Some help, please?

Phone shows network but no data connection or calls possible

I have purchased a used Note 4. It was already rooted so i went ahead and installed Nameless ROM and the appropriate bootloader_modem.
Now, i have no data connection and can't make any calls. Even if the bars show that there is coverage. WiFi works fine.
My first idea was to revert it to stock so i downloaded the N910GDTU1COJ3_N910GXSA1COJ3_XSA stock rom and flashed it in Odin. Full wipe and cahce clean after the flash.
I am still facing the same problem that the phone doesn't have data or voice service. Any ideas what else to try or what could be the problem?
TIA
Anyone?
for me...i always lost signal... i dont know why...910f
Same issue
Went back to stock ROM a few months ago, but this has just started with me. 4 days and not able to connect to any data service.
Tried new Sim and manual network selection, just refuses.

Hi @dosada, i guess I.have the same problem as you, I can't connect to any 3G or 4G anymore. Now, I only can use 2G and Wi-Fi. so try to put network mode to 2G only, because if you put network mode in 4g or 3g or 4g/3g/2g automatic or 3g/2g automatic you will always end with Emergency calls only or no service. I already asked help for that but no one can solve it. I already tried everything I know but no way, no one can solve it. So just courage and let us know if you get solution somewhere.
I think that it is the last time that I use or buy a Samsung phone, they really suck recently. it's better to spend our money to buy other phone than Samsung, they lost the trust of their customers. They were number one but now...puffff...
