[SOLVED] No 3g after ICS

9020T with stock ICS -flashed yesterday.
But 3g doesnt work anymore??
Any ideas?

Same problem here. Based on my monitoring of the phone status, it doesn't connect to the 3G networks anymore just EDGE and UMTS.
I don't even know what it's supposed to look like on ICS when the network is 3G or if there' a live data connection. I think the network signal bars are supposed to turn blue. But they don't without wifi.
Upgraded to 4.0.3 from stock 2.3.6 on i9023.

I also upgraded from stock 2.3.6 on i9020T
Everything else is working great except for 3g..
I use a program called notification toggle to move from wifi to 3g and it just crashes if I press 3g.
I go into data settings instead and everything looks fine ...data is enabled etc.. but 3g icon never appears in the signal bars ,so cannot connect.
Anyone know how to fix this?

Anyone ?
I Need help getting the 3g working or will have to try and go back to 2.3.6

I had the same problem after going to ics from 2.3.4 and then to 2.3.6. go to network settings and just refresh or delete and renew the settings. it will scan and take like ten minutes. it will find tmo and att. pick tmo and you should see the mobile network work now. did for me. 3g and edge and all

Ok thanks
But can you explain that a bit better..step by step...
click this..click that etc...

I had to do a factory reset to got data working. 9020t

From the top of my head... If rooted
Download root explorer
Locate efs files....
Move the following files to root of SD card:
Nv.log
Nv_data.bin
Nv_data.bin.md5
Once ur done reboot and u should be ok
-Google Galaxy Tab

Also experiencing this. 9023
Factory reset = no dice.
Gonna try to narrow down the problem a bit. I flat out refuse to root my phone to fix an issue caused by an official OTA update.

Same opinion here regarding not rooting. Too bad the factory reset did not work for you, because it just did for me. A great relief that it did, too. Apparently the APN settings remained after the reset and it got 3g and data connection again even during the phone setup.

How did you do your reset?
Settings - backup & reset - factory data reset ?
or
bootup the device holding vol up power and do reset from there?

why dont you guys do what i said to do?
go to settings --> click more at the top --> click mobile networks --> click access point names --> opn the options menu and select reset to default.
now click on network operators in the mobile network settings menu --> allow it to search (can take a while)
here's where it takes a little fiddling. i actually selected ATT first so that it would change all the settings. then i selected tmobile afterwards. then it just connected to the mobile network without a hitch. i believe i rebooted but am not sure.

ok found it!
i9020XXKI1

Seems I am having the same exact issue, with that exact same baseband. Only I am running into it with CM9 Alfa 17.
Sounds like some files for the radio or something got left out.

Not sure if it's related but I can't get a signal either on my i9020a now. Flashing to a previous gingerbread rom doesn't bring it back either.

Flash kf1 radio best one so far

Check your APN settings. Also, try a SIMswap. Old sims do not like new phones, and mobile data is the first to go.

APN is done by Vodafone automatically, checked it manually too. It's proper. Of course I cut my SIM. Big sized SIM can't even fit this device.

Ahhh, there we go. Try a different SIM. Either it's too old (anything before January 2013 is too old), or you're one of the 50% where cutting the SIM causes problems.
(Yes, I know it doesn't fit. 30% of my day revolves around people with faulty sim cards.)

I get my N9005, telephony functions are working (calls - message - wifi bla bla) but I can't use my mobile data. Neither 3g nor 2g.
When I activate mobile data icons are existing like there's a connection. H, H+, E icons exists but no connection. I upgraded my firmware to NF4 too, did all wipes but still not working...

tried update modem?
basic problem lies on the APN setting. but if you said you have checked it and all ok, try to update your modem into your device latest modem.
I use a big simcard cut into smaller one, and no problem. I have old simcard since 2011 as well.

Like I said in the OP. I already upgrade my whole firmware. Modem is updated too but problem is still same.

Put your SIM card into another phone and test.
You may have to check with your mobile operator for data-service registration.

u can try what vndnguyen said.
But, just to comment... actually, when you upgrade firmware, normally it won't flash any modem/csc. You will need to do it manually.
This is what I know when I experienced on any official firmware upgrade on my device.

Hmm, I did the process with Odin. Check SS Isn't that a modem ?

yep. that's the modem.
pull it out from the zip. and flash it from ODIN under CP.
when you go to download mode, make sure you switch your phone completely OFF first. then go into download mode by 3 combo buttons.
if 1st try fail, no need to worry. repeat the same steps, and you are good to go.
Sometimes I need 3 times to succeed. Don't know why also. Sometimes 2 times, and sometimes 1 time also no problem.

I (as with others) are having the exact same issue and is actually something that has been brought to Google's Attention: https://code.google.com/p/android/issues/detail?id=63524 Note that the Android Issue tracker refers specifically to The Nexus 5 but other users in the page are also having the issue on other devices, like you and I.
I have tried multiple different possibilities to fix it but still no solution.

My bad guys. My internet package was out. (I didn't pay -.-) Paid now it's working.

Just so that I'm clear. You did a Factory Data Reset in the Settings menu? Not a Reset Network Settings?
I'm experiencing the same issue with my S7 Edge.
Thank you,

Even without the icon, you can turn hotspot on and off in Settings.

Can one of you send me a unroot
odin with home.csc so i can get hotspot again pls

I rooted PG1 and had the same issue. Miss Wifi Hotspot completely no icon not in settings. I unrooted and made sure tethering was install in my stock rum. Re-rooted after getting pass the auto activation process. I check to see if tethering stucked n yes it was. Fixed.. root unroot until it sticks

One more think i did do the home.csc but didn't work for me.

I've found the cause of this. When you disable or turn off security policy updates under lockscreen and security, it will stay indefinetly.

Yeah, I finally found out from some techs that they lo-key removed the hotspot in an update because they claim that it causes the phone to overheat.

WiFi calling doesn't work on OP5 with Oreo

WiFi calling was working fine with nougat, it doesn't work after I upgraded to Oreo. I have OB4 installed on the phone with T-Mobile USA. I am in remote place without T-Mobile signal. I put Sim card into my Nexus 6, Wi-Fi calling works fine.
So Oneplus team breaks Wi-Fi calling on Oreo?

I have TMobile and I'm on OOS 5.0.1, no issues with WiFi calling here.
Occasionally I will have to toggle airplane mode for it to work, but I had that issue before Oreo.

Still doesn't work on beta 5

Have you enabled WiFi calling in the Sim & Network settings?

If you are using Magisk v15.3 get module VoEnabler v1.1 created by Toucan.
I did not even seen option in the sim and network until I install this module...

I have no problems with US T-Mobile, although it does not work with German T-Mobile. In another thread it was explained that Oneplus and the respective carrier need an agreement to make it work. If your carrier doesn't have one, it will not work.

I don't have the option in Sim&Network for WiFi calling until I did fresh installation. Now it is working.

That's true, without the agreement of German T-mobile no volte or vowi won't work. They want you to buy a galaxy s8 for example which is enabled for both...

It is really strange. WiFi calling option disappear after I switch on the cellular and then switch back to airplane mode.

If you are using magisk with OB5, flash VoEnabler and it works.

I know why. The t-mobile sim card must be selected for data.

i know this is a crazy old thread, but have you ever been able to fix this? i'm still having this issue even after ditching OOS and going to a custom ROM. this has to be a bug in the modem firmware, but i've reported it to OP and they seem uninterested in fixing it...

Nope. I even installed enterprise networking equipment in my home since and it seems to be better (probably placebo). I have also done a factory reset which didn't help.
It seems like I can always receive a call, but can only make a call 75% of the time. There has been times where I tried to call people I know several times when it was acting up, then I would message them telling them to call me and my phone rings minutes later.
What usually works (but not always) is to reboot the phone, then turn airplane mode on, wait a few minutes, then turn it back off.

that may be a different issue then...mine always works when it's turned on, but seems to just stop working randomly for no reason. the vowifi and volte icons disappear, and the only way to get them back (and get it working again) is to toggle airplane mode or reboot the phone...

S10+ Internet Connectivity Issue After Updating to One UI 2.0

So my s10+ (G975-F) was working just fine. After updating it to latest update, it has been acting really weird. The internet would stop working all of a sudden, like messages on messenger would not send, snapchat would not load, same with fac3bpok and chrome.
Anyone else facing thiis issue? Any help would be appreciated.

your mobile signal really poor.... one bar only...
wifi signal also 2 bar only, but... are you sure your wifi connection also running good ?
Sent from my SM-G9750 using Tapatalk

I have similar issue: No mobile data connection since updating to Android 10 on 12/31/2019. WiFi is working fine. Tried wiping the cache partition as suggested above. Tried restarting, resetting network. Tried calling carrier (Redpocket/Verizon) who did provisioning and taking out SIM card and reinserting/restarting. When switching SIM card to another phone (Galaxy S8+ using Android 9), no issue (Internet worked just fine). But another SIM card on my cell phone (Note 10+) didn't work either. So clearly the issue is with my phone (after the software update), not carrier. Took the phone to local Samsung store on 1/2/2020. Was told I was the first one reporting this since the Android rollout. They suggested factory reset which I am very hesitate to do. Then they suggested waiting for a patch to be released, if there will be one ever.
I am using Samsung Note 10+. I am in California.
Any advice? Thanks
