Surpisingly TATA Docomo 3G is not working on my Samsung Focus!!! Including 2G!! Changed to 3G in settings and tried adding APN (TATA.DOCOMO.INTERNET) AND (tatadocomo3g), nothing worked. Vodafone/Airtel networks are detected and works without any issues. It switches to 2G when 3G is not available. Does anybody facing the same issue?
Never mind guys.. I got this thing working All i had to do was to perform hard reset..
I use Docomo, and am from Mumbai. Recently, I had gone out of town, my Focus was showing 3G instead of usual E (EDGE). I did not need to change any settings, and the internet was loading way faster than on 2G. Was in Maharashtra.
Does any one have the same trouble as mine? When i switched from wcdma to gsm i could not use internet anymore. Im currently on three UK. And it is I9505. What could the solution be?
Is it cos three don't have a 2g network?
Hi everyone, I'm new in the forum although been following it quite some time.
I have a problem with my i9505. After a trip to Korea my phone hasn't been able to get 3g connection at all in China Unicom network before the trip there was no problems. (I wasn't able to get network in Korea at all btw). Now connection is always with EDGE and GSM only.
Anyways the firmware I have been using is the new (3g connection with this firmware worked fine before the trip)
United Kingdom BTU (September 2013)
PDA: I9505XXUDMH8
CSC: I9505OXXDMHA
Version 4.2.2
After the problem occurred I have done factory reset and cleared cache. Also tried the new german BTU PDA: I9505XXUDMH5, CSC: I9505OXADMH5 Version 4.2.2
Also tried different modems: ZCUCMH1, XXUDMH8 and now it is XUBMGA - none of these work. I can select all LTE/wcdma/gsm and wcdma only, gsm only etc settings from the phone but only gsm or wcdma/gsm works. Other modes don't even find any networks (in Korea it didn't find any networks with any mode)
Factory reset and clear cache was done after every flash.*#0011# shows only GSM 1800 available so for some reason it seems that the phone thinks it is just a gsm phone or does it get it from the network?
Imei code shows up normally in the "about phone" menu and I also called China Unicom operator and they said that they don't even block any imeis so that shouldn't be the problem. Internet also works so the apn settings are ok, just that it is on edge only and doesn't even try to get to 3g.
I also tried the simcard with my friends i9505 and it got working connection with H+ immediately. I tried her working card on my phone and it was still only in gsm/edge mode. Her phone had xxubmga/xxbmg3 software inside so I tried the same modem with no luck.
One thing is that I can't downgrade the phone anymore since I installed the SELinux forced UK stock firmware. Also knox warranty is 0x1 since I cfrooted the phone at one point when I had gps problems. Still even after that the phone has worked normally with the said uk stock firmware for a long time. It seems that the korea network messed the phone up somehow?
Anyways, any tips about how to fix the problems would be greatly appreciated.

Just a shot in the dark, try *#*#4636#*#*
Under Phone Information > Preferred Network, Make sure you have the proper network selected. I had a similar issue connecting to LTE, it kept defaulting to WCDMA.

The code did't work but I got to that menu via ShowService Mode app. Chose wcdma all which also set the default network in settings to wcdma only.
Anyways no luck I checked with *#0011# and it keeps jumping between three screen No service, No sib19 or sib19 received. At one point it showed hdsp0, etc but I didn't get the chance to capture that screen. Attached are the files.
Just noticed in the service menu that the NAS information - MM reject information list says "Type 1, Cause 15 460-01, UMTS"
I guess this means that the phone is not allowed in 3g network? Operator problem, phone problems or sim problem?
I'd think it is not sim problem since it works in another phone but could the operator still be blocking or not recognizing the phone as umts device? Should call operator? Though they said they don't use blacklist at least or could the korean network had ruined some phone's own network capability database somehow?
Edit: also noticed in service mode that there is plmnsearch going on so it is trying to find suitable basestation to connect but I guess it can't find one. It gives NoCellAvailable(5) error. Crappy modem? although as said previously it used to work. I'm also in Shanghai city center where my friends' phones work just fine - and mine used to.

You need to contact your provider and see if your account is setup for 3G, otherwise it will not access that network.

I called the operator and they "refreshed" my 3g settings. Also my sim worked with my friends phone as H+ so it should be activated. Can operator choose the device to attach to 3g network by phone/imei instead of sim ?
It's supposed to be by IMEI.
Sent from my GT-I9505G using xda app-developers app
anyone any idea? is it because of the imei number?
hey guys, could anyone resolve this problem?
happens to me since I got my s4 after performing root and debradign

--------------------
I have the same problem. An internationally unlocked Samsung S4 I9505 (LTE) lost its 3G connectivity during a visit in South Korea. The strange thing is that there was connectivity during the first two days of the visit and only then it lost connectivity (there were no reception bars and an icon similar to 'no parking' appeared. Also - searching for service provides did not yield any provide). Only after landing few days later in Taiwan, reception was restored. But, it seems that from then on, the telephone operates only on GSM. Setting it to 'WCDMA only' results in the same 'no parking' icon and no data.
Will greatly appreciate any advice that will help me restore the WCDMA operation.
Same problem after visiting Korea. Have you find a solution?

I experienced the same problem and it also started at Korea (a strange co-incidence). It lost all network connections in Korea for 2 days and when I continued my trip and flew to Taiwan, the connection restored (without me doing anything). But a few weeks later I did note that everything is very slow and I found that the phone operates only as GSM (I was not aware to this because it was set to select automatically between LTE/WCDMA/GSM). Since then, it seems to operate only on GSM (if i set to 'WCDMA only' - it will not connect and a grey no- connection icon appears (similar to "no parking" street sign). I Did try 'almost everything'. I rooted, installed lolipop and back to Kit Kat (this morning). To my surprise, i had a few hours of normal operation (the letter H above the data icons as opposed to E when it operates on GSM). but after a couple of hours - "no parking" sign again and it will not work when set to 'WCDMA only' (and will operate when set to 'GSM only' but of course very slow data transfer). Very frustrating! Have anyone find a solution??

Dude you saved my phone!!! THANKS A LOT
Hi all after wifi not working anymore I bought a refurbished motherboard for my 9505 LTE version. After replacing it wifi is working great but I can't seem to be able to connect to 3G. In info menu (*#*#4636#*#*) I read -voice network: GSM and -data network: EDGE, no matter what I set in preferred network type. I contacted phone company (3 Italy) and they say mi sim card is correctly registered on the network and I should get at least H+.
Tried all the latest modem/bootloader avaiable, now I am on I9505XXUHQC1 (GSM/NON-HLOS COMBINED).
Also tried manual network selection and I can only have signal if I set 2G as preferred network type in Settings-WiFi and Mobile-Mobile network.
Any ideas?
Thanks
Whenever I switch to 3G only, my SIM Card signals go down and when I search for network operators, none of the operators are found. I'm living in Pakistan and my area is 3G/4G granted and my SIM Card is also 3G/4G but whenever I keep it to Auto, my signals come back and my phone runs 2G or E instead of 3G. It used to run 3G before but when I installed the latest firmware on my device using Odin, it never switches or finds 3G operators or network. I didn't remember the version of the old firmware installed. Can anyone help me?
I have searched the whole internet but none of the fixes are working.

What firmware did you flash in Odin? Was it the latest firmware for the g550t2 and for your country?
