Guys I have a strange problem my razr wont connect to any of the data 2g or 3g only on custom roms like 4.4 Kitkat,Carbon rom etc . I flashed them on slot 1,2 even on stock slot but no luck.. I tried to change Baseband But It always failed So guys help me.....
Edit 11.12.2013:::
I fixed the problem partially..
I fixed the network mess It was bad radio which did this all I flashed ICS radio and now network works fine in all roms (Stock and Custom) BuT bo mobile data on any of them
Edit::::
Now Phone says NO SERVICE on both stock And custom rom but reads sim card contacts & SMS's...
I tried reflashing stock rom But no success. Help me guys...
2g/3g for many of the newer roms has been a problem with both the XT910 and XT912. I know with cyanogenmod 10.2 I'm still not able to connect to 2g/3g although LTE does work. With the newest release of cyanogenmod 11 though I do get 3g and LTE, although some people have been reporting they are not. Seems it's headed in the right direction. Give the latest CM11 build a shot and see if it works for you.

kk but still i have no luck getting 3g on newer versions too.
Is there any APN that saved in your network setting? If it doesn't, set it and save it by hand.
Sorry for my bad English
yup apn's are saved as usual

Can you make a call? Did you have paid the SIM card cost?
Sorry for my bad English
Yup my SIM is in contract and working on other phones I can make and receive calls but not on razr I get NO SERVICE message
Open the phone (or dialer, whatever you would like to call it) and Dial *#*#4636#*#* and go to Phone Information and tell us what the preferred network is.

Also:
What ROM did you get LTE Only on?
I learned that sometimes ROMs can mess up NV's. The only way of fixing this is to wipe everything and start fresh. And when you are flashing you cannot downgrade, it will fail every time. You may already know what I am telling you but just in case.
And what carrier are you with?

I purchase a new microSIM & also did a data / factory rest from phone boot option ( u know from tht recovery option comes after rebooting in boot seq mode) to solve the problem but no positive result ... though i found one thing if u go to settings -> more -> mobile networks-> select network ... there you'll find 3 option
1) 2G only

3) automatic default

hey faheemakbar18 how much time & money it took to fix that problem

XT910

Hi. I have XT910 for more than two years. After brought the phone from Australia to Hong Kong (use Hong Kong SIM card) and back to Australia (replace SIM card with Aus one), I have the same problem as you. Phone can make voice call, but no mobile data connection (3G, 2G).
Want to know if your problem is fixed or not?

Hi. Can you tell me how to fix the issue: no mobile data, and phone saying "Syncing SIM card contacts"? Thanks.
Hello Guys,
I have a Tmobile s6 edge. I have unlocked it to use in Brazil. Everything was working fine but I had a trouble with root and ended up soft bricking (not passing the Tmobile logo screen)
I managed to reinstall Tmobile stock rom and make it work again. All was fine but this afternoon the phone decided not to register on the network anymore. Weird thing is that I still have connectivity over 4g. I tried a Tmobile Sim card and get the same problem.
Any suggestions? Should I root it and flash a custom rom? Different radio? Everything else is working fine.
Thanks!
Turned out that the imei was blocked. I managed to change it through a company in the US. Now it's back to normal.
Go to settings > mobile networks > network operators and select search automatically.
If this doesn't helps then tap on search networks and select manually,this worked for me.

Check your IMEI is normal
Hello
Same problem, i can not resolve

I've brought this LG G3 Verizon back in June. I'm running CM 13 20161102 build. Everything seems to work fine except the 4G services. When I change the preferred network type to LTE, the network bar disappear and shows no service. 3G and 2G work fine. I've also tried changing the preferred network type from *#*#4636#*#*, still no profit. I also tried changing the APN, still no luck. Please help me. (I'm using this phone in India). Thanks in advance.
UPDATE: I just found out that I have to enable the LTE bands. So using TWRP, I restored the stock KitKat ROM backup. Then I used Shortcut master to access the hidden menu, selected all bands and restarted my device. Then 4G seemed to work. Then I again restored the CM13 backup. I saw that the problem still persists. I want to know if there is a hidden menu in CM13 like the stock ROM has? If yes, please tell me how to access it and enable LTE bands. Thanks.
Hi!
My phone is Redmi Note 3 SD, Kate version.
I've been using cm14 for a few months and then decided to flash nitrogen os. After flashing I can't call or receive calls from anybody, since my phone can only connect to LTE, but not 2g or 3g, and my network operator doesn't support VoLTE. I can still use data connection on LTE and send/receive text messages. My phone also connects to my Wifi network. When I select 2g only, 3g only or 2g/3g in settings I get no signal at all. My sim card and carrier (while connected to LTE only) are being detected, I have the correct IMEI. I've tried flashing MIUI through fastboot, flashing CM13, CM14 and flashing different kate firmwares on every rom. Does anybody know what to do?
I solved the issue by installing Network Guru and selected WCDMA in RAT locking menu. Then i selected clear forcings and the problem was gone.

I have the same exact problem, but on a Kenzo.. I don't have 2g/3g in Nitrogen OS, Xenon HD or Lineage os... but I have them on any miui ROM (official global dev/stable and xiaomi.eu)
But the strange thing is that I've been using Xenon HD and the Nitrogen OS for months without any problem... Before I try your solution, can you confirm your solution applies to the same problem?
TIA,
Gustavo Melo
I didn't have 2g or 3g on MIUI roms too. I recommend you to try it, you've got nothing to lose
You need root though.

Well... I don't know what to say... I tried the app still on miui (xiaomi.eu), and did what you described (even if the problem didin't exist on MIUI)... Then installed Nitrogen OS and... I have 2g/3g!... the only difference on this install is that I activated the phone without the SIM...
One of the two: or the Network guru app I used on miui persisted even after installing Nitorigen, or activating without SIM did the trick...
Thank you either way!
Eject your simcard
*#*#4636#*#*
And choose LTE,wcdma,gsm auto

Oh my God thank you! I finally have connection on H and 3g.
I am facing same problem on poco x3 nfc from last 4 days , during 1.5 years it was working perfect
please give me the solution and tell me is it completely software problem or it might be hardware problem??
Hi, I downloaded and installed Lineage ROM, everything was working fine but I found that I was not able to send text messages (receiving messages was okay), I tried change values under test menu (*#*#4636#*#*) but problem persist.
I tried clean installation of new ROM (Aosp).
I tried install new firmware from:
https://forum.xda-developers.com/re.../firmware-xiaomi-redmi-note-5-5-plus-t3759683
And baseband from :
https://androidfilehost.com/?fid=746163614322262750
And finally, text messages are OK, unfortunately I am not able connect to 4G/ LTE networks now. Only 2G and 3G networks are working. LTE services were working without problem on original Miui and Lineage ROM.
Can someone try help me how solve it ? I would really appreciate any ideas.
Do you think this can help?

Thanks in advance and happy weekend
i have the same question! +1
I tried fresh install original MIUI ROM, but it did not help
http://en.miui.com/getrom-340.html?m=yes&mobile=2 .
LTE is not available still.
I did not try this method still: https://androidfilebox.com/app/redmi-5-plus-modem-firmware/
But I don't have another option I guess.
With LTE no Problems = https://forum.xda-developers.com/redmi-note-5/development/rom-omnirom-t3823189
Unfortunately LTE is not working on this ROM (Omni) for me too, but I expected it, because as I wrote I tried original MIUI as well. It's problem of wrong firmware, baseband, modem or something, because hard reset or flashing new rom don't fix it. Btw, this morning I was in big city in my country and my phone was able connect to LTE, but it was 1800 or 2100 MHz, which are available only in bigger cities. When I came back to home, it showing only H+ again. It seems my phone is not able to connect only to LTE on 800 MHz (B20) currently, which is most widespread LTE frequency in my country and this one is only available one in my location. And I was able connect to this network before. Unfortunately I don't know how I can bring it back.
Solved.
My friend share her .xqcn file with me (she has same phone) so I flashed modem file via QPST Flash Tool to my device. Xiaomi started receiving LTE in my location- B20 frequency band, unfortunatelly it was continuously connecting and disconnecting between "no signal" and 4G.
The next step was flash MIUI 10 Global Beta ROM 8.8.9 to my phone via Miflash. LTE seems be stable and fully working now.
