I just modded my phone (unlocked, custom recovery, s-off, super cid) but now that I have a custom rom I have no service. Well it says I have a couple bars but its basically just the basics I can call and text but no internet. I tried flashing the tmobile radio but that didnt fix it. I was using paranoid android but I noticed the problem so I tried a different rom but Im still having the same problem. Does anyone know a fix for this?
Also in my settings it says "Mobile network state: Disconnected"
Check your Apn settings ?

Hi guys
I have problem after rooting DHD with AAHK with gprs/EDGE data and 3G data. GSM works fine, WiFi, GPS also but I cannot turn on data over mobile network. Tried different ROMs, flashing different radio versions, return to stock rooting again and still nothing. Tried to change APN settings, pull off the battery also but no luck. Also I tried with *#*#4636#*#* to switch radio off no luck. Is there any way that I can troubleshoot this to find out what is causing the problem. My radio version is
12.56.60.25U_26.10.04.03_M
Sabsa Prime V8.0 - tried CM7.2, stock, Revolution HD, Jelly Time, Pacman Jelly... no luck
Thanks in advance for any help
I think the problem is with your APN settings. Something like this happened to me recently and it was because my APNs were messed up. Try this app to save your APNs. Maybe there's some error in what you're manually entering. I see no other reason as to why your mobile data shouldn't work on any ROM, especially if you're getting a signal.

Thanks on your reply. I found that the problem was with my operator, because they disabled the data service for my account. I thought that problem is with my phone but it was on their side. Thanks again
Hi,
After flashing one of the CM11 nighties I started getting the message "error while searching for networks" when as msg says searching for networks, I found out too I can't use any USSD code I get the message "Connection problem or invalid MMI code" however I am connected to my local network and able to use LTE.
Flashed the latest modem version and for some time it works but now again it doesn't work, attempted flashing again and issue persists.
Attempted a newer version and switching to Paranoid and issue also persists.
Help?
My device is a SGH-i747m from Telcel (Mexico).
Does this happen with a completely stock ROM?
Sorry for late reply, my phone got bricked
Anyway, I was able to use USSD codes again after going back to 4.1.1 stock, therefore the problem is either 4.3 or the modem upgrade which disabled USSD codes.
I previously had a Resurrection mod that was using jellybean. The new custom mod i installed is Cynaogenmod 12.1 lolipop.
After i installed the new custom rom i got a "Root Access Possibly Lost. fix" error message straight from CWM recovery mode. After the first long boot of the new custom mod i had no cell service. Also, i tried restarting into CWM but i think it is now lost because of that error message.
Anyways, i looked at the back of my phone and the IMEI number matches the number in the About Phone. Another thing of note is that there is no APN. I tried putting in the APN settings but it wouldnt save. It says: "Acess Point Name settings are not available for this user.
I'm new to rooting so, im not even sure how to root the phone again. Should that be my first step? WIll it be different because it has lolipop installed?
My phone:
SGH-T999
android version: 5.1.1
UPDATE Ok, it says "No Service" but i can make phone calls and send text messages. However, my DATA service isnt working, when i turn off WIFI i cant use the internet. Thats the problem.
Is the phone running the latest bootloader and modem?
Hi, I'm having some troubles here with a GT-9192 (Stock ROM 4.2.2), one of my friends brough me his phone which he tried to root (I don't know how or what software did he use to do so) and I think he did something really wrong because now the phone boots as normal but doesn't get any network signal at all. SIM1 doesn't recognize any SIM inserted, SIM2 does but there's no service at all, every time I try to search for a network provider it fails and if I select automatic selection it says "registered on network" but there's no signal at all.
I tried flashing today Bliss 6.0.1 ROM and it flashed nice, booted up and worked as intended yet the device has no network signal. WiFi and bluetooth work nicely.
What can we do to fix this? I did a Nandroid backup of the official Stock ROM on TWRP 3.0.2-1 and I just did a restore. Do you need more info? I'm out of ideas.
Recently i have entered some state in which mobile data is busted on my phone. I have tested multiple android pie roms to find the same thing in each. When i flash the latest stock android (PQ1A.181205.002), mobile data is fine. In this broken state i can see the signal bars with a little 'R' by them (notification on lost mobile data connection Data roaming is turned off. tap to turn on). Every time i navigate into Settings> Network & internet > Mobile Network > Advanced > Carrier Settings. The screen will flash and take me back to Mobile Network, this happens with every custom rom tested. The app SprintDM tries to set up the phone 5 times and then fails. Phone codes seem to have no effect. the code 4636 will allow me to view current info in which it says mobile data disconnected. It doesn't appear to matter if i connect to wifi and allow the basic stock apps to update first. Reboots do not help. I even tried flashing the modem and radio for PQ1A.181105.017.A1 and OPM4.171019.021.R1. I can also say the phone app shows a message "This device is not supported and phone calls may not work correctly". Phone calls work fine. Previously i was running LiquidRemix (10.0.2) just fine, everything working. Randomly mobile data died so i tried a update to LiquidRemix (10.0.3) and still busted. Tested multiple other PIE roms to find the same. And again if i flash any stock firmware mobile data is fine. Anyone else see this or have an idea of how to fix this for custom roms?
I rooted my pixel2xl yesterday and installed Havoc OS.
Today I was out with my family and was trying to navigate via Google maps and it continuously displayed error "try again"
Status bar was showing lte connection then I tried opening chrome and was unable to use mobile data even if it being on and active.
I am planning to move to Stock again tomorrow

vipulkarkar, did you find out any other additional info on this? I went back to stock and everything is fine but would very much rather be running a custom rom.
Just seeing this post, fortunately, I've not run into this issue on stock or custom roms ... What I do run into, on stock or custom roms, is when I leave my house, with a T-Mobile CellSpot, I tend to switch to 3G or H+ in an LTE area. I sometimes have to cycle airport mode a couple times to get LTE back.. So odd and annoying!
Is there something we Sprint users could do to help the devs include Sprint connectivity in their roms? Like provide a nandroid backup of our device or ?
