Hello,
I have an I9505 phone, but since last week, I lost my connection. When I configured my phone to GSM only (2g), I got my connection back.
When I set my phone to LTE / WDCMA (automatic) I lost my connection (mobile and internet).
Thing I have tried:
Another SIM in my phone, doesn't work
My SIM in another phone, works.
Reset to Samsung Stock rom. (with different modems)
Tried different APN's.
Does someone have any idea to fix this? Or is this a hardware issue?
Regards,
John.

Hi!
I have a problem. The phone is refusing to get a service on GSM. It has just stop working.
Initial i thought it was wrong with my SIM, I ordered a new one and the problem remains.
It can connect to 3G fine, and sometime I can get on the GSM bands but then I have edge (I always use to have GPRS (G) )
At home I only get "no service / emergency calls only".
I've tried another sim from another provider and i get GSM from them.
My girlfriend has the same provider and she gets full coverage on the same location as me when all I get is "no service"
I've tried changing modem and roms. No success.
Currently i have CM7 with MIUI, problem remains.
Anyone has a clue whats wrong, my antenna? need service?
Hello,
I upgraded my plan to one which includes LTE data transfer. When I turn on mobile data connection (with data roaming allowed) phone connects only to 2G EDGE network. There is no way to connect with 3G/HSPDA/LTE despite good signal and proper settings (preffered network type, apns etc). I've tried:
- few different modems/radios: XXUHOB7, XXUHOB8, XXUGNG8,
- few roms: stock 4.4.2 I9505XXUGNG8_I9505YXZGNH2_XEO, CyanogenMod 12, CyanogenMod 11, I9505_-_Official_Google_Edition_5.0.0_by_Jamal2367_Stable-R2.1 and JFLTE-GPE-20150315
With no luck. I didn't used data connection a lot before so I can't say when the problem started to occuring. I tested my SIM card on different phone and LTE connection works... I attached screenshot from "Advanced Signal Status"
Do you have any ideas how to solve this issue?
Thanks!
same error here!
any solution??

It really depends on what bands your carrier is using. For example, in romania, we have a carrier (digi mobil) that has 4g signal only on the tdd 38 2600mhz band, a band that our phone (i9505), doesn't support.
You should look into your carrier bands, get info on what bands are they currently using and then see if they coincide with the bands that your phone supports. What variant do you have and on what carrier are you on?
Is your phone showing the correct imei?

How do i know if my imei is "correct"? I checked my imei and i inserted it in a site and i found the specifications of my phone as they should be, but my 3g and 4g are completely dead.
Does the imei in the phone match the imei on the label under the battery?
Hi everyone !
Lately I went to a place were 3G/4G was not reachable and it is there that i noticed that my brand new Moto X play couldn't get any connection in 2G (GSM) mode even if the place was fully covered with 2G/EDGE (GSM)...
In 3G/4G there is no problem only on 2G (GSM).
I tried in the settings to put 2G (GSM) only and I can not get any signal even now that i'm back home ....
I tried a factory reset from the recovery it did not work :crying: Do you have an idea on how to solve that problem ?
I also tried to use the sim card with another phone in 2G (GSM) and there it works fine with maximal signal ....
Thanks ! :laugh:
Hallo,
I did a test and I got the same "problem".
Turned 4G into 3G...no problem.Still connected..
Turned 3G into 2G....no signal.
Turned 4G into 2G..no signal.
You can try to switch networktype in *#*#4636#*#*
No time for me now....I will try it later on the day.

I just tried it and turned the networktype to "GSM only" then i got no signal just like before. If i try to use another type like CDMA/GSM it connects to 3G and works but still the problem with the GSM/2G....
Hi guys. I'm not experiencing this problem on my XT1562. switching between bands is fine and working on my device. What kernels are you guys using?
I'm using the stock kernel, I just flashed the OTA (6.0.1) from the stock recovery
Same Problem, more information
For my Moto Play X I have a very similar problem:
4G works, but 3G and 2G do not. If I'm connected to a 4G network, I see that there is reception and can use all data transfer functions. But when I want to do a call, I get a timeout. When I'm in a place where there is no 4G network available, I see that I don't have signal - but the network is shown in the list of available networks for manual selection.
As I have a dual SIM variant (stock ROM, not a custom modification or "upgrade") my second SIM does work like a charm. I tried now and swapped the SIMs - and it seems that just the SIM1 slot is having those problems. The same SIM also works perfectly in the second SIM slot.
I also tries to reset just the network settings (an option provided by the stock ROM) but this didn't change anything.
Next step I'm currently working on is doing a factory reset - will take a while until backup and restore will enable me to see the real result. I'll keep you up to date....
UPDATE: factory reset didn't change anything - will send phone to repair now. :,-(
Facts:
- OnePlus 2 (European Edition, Germany)
- CM13 (13.0-20160721-NIGHTLY-oneplus2)
- Provider: Telekom (Congstar)
My OPT refused to switch to anything more then EDGE (2G) a few days ago. First I though the network was down but after a few days I checked with other phones and only mine wont switch to 3G or LTE.
When I tried to cheange the "prefered network" toggle, I switched it to 2G and now I can't switch it back to 3G or LTE. The options are still there but when I select them they instantly switch back to 2G. Even in the Advanced menu that you can enter by dialing *#*#4636#*#* I can't change it. The setting is fixed to "GSM only".
When I search for network I can only find 2G networks. In the Results are only Vodafone 2G and Congstar 2G which is my provider.
Does any one else have a similar problem and maybe a solution?
UPDATE:
I reflashed the stock image and everything worked there. Then reflashed cm13 and now I have the same error again. So it seems to be a software bug in cm13 not a hardware bug.
UPDATE 2:
I flashed the modem from stock again. Still not working. Than I disabled the modem from the service menu and enabled it again. Then it worked for a few days but then I was back to only 2G. Now the reflashing trick doesn't seem to work anymore.
I have no idea how to fix this does anyone have a clue? I can't be the only one with this problem.

You can't have 4g/lte active on both SIM cards, so solution is to put phone in flight mode, switch your primary SIM to 4g/lte which should put your secondary into 2g mode and then you're set.

What he said.
That's how I fixed it. Still wondering why this is possible with the stock firmware. At least I didn't notice the problem with stock.

because on stock it does this automatically. You can change the network type of the SIM on which data is enabled.
The other one wont even show you the option
Hi all.
I’m experiencing a problem with my dataconnection which renders my data connection almost unusable.
Hope someone can point me in the right direction!
The situation, I am using a Oneplus 6T with 2 sim-cards. One for calls one for data. The sim I use for data loses the connection multiple times while commuting to work (train).
It happens on the same locations so I assume it has to do with switching between towers. The connections completly drops to no signal (the other card still has a signal).
After the connection drop one of the following happens:
- Reconnect to 4G after a few secons to minute(s)
- Reconnects to H+ and stays connected to H+ until I switch aiplane mode on and off). Even when getting of the train and waiting on the same spot it hangs on H+ until I use airplane mode.
What did I already try.
- New SIM card from provider (Tele2)
- Complete profile reset by provider and check of APN settings
- Tried both SIM slots
- Tried the SIM card in another telephone (connection does not completely drop)
- Use another provider (T-Mobile) with this phone. The data connections seems to work fine on T-Mobile.
So it looks like a combination between Tele2 and the Oneplus.
(By the way Tele2 falls back to h+ and 3g from T-mobile if they can't provide 4G)
Thanks for reading and all tips and tricks.
