You need to swap the SIM card/the phone with another phone/SIM card to eliminate the causes from the SIM card/the subscription/the network...
After eliminating all causes from another sources, you can start to fix your phone.

Thanks for your advice i change my sim but nothing so i do a factory reset and everything now is ok ....:laugh::laugh:
:good: FINALLY SOLVED :good:

My friend has the same problem. He was using Iphone 5s and I convinced him to switch to Samsung/android and he did . But so far its been problems for him on his S5 duel sim SM-G900FD.
I tried to fix it for him but no luck so far. Things I tried,
- Factory reset
- swap sim
- use only one sim
- software update from (XXU1ANF7) to (XXU1ANH2)
Last thing i am doing for him before I give up is to turn off the smart switch between data and wife. Other than that i'm not sure what to do. He always fix the issue by going to airplane mod then turn it off, but it will come again eventually.
Any help is appreciate it as i am trying to get a new guy into android world

1- Does this SIM works fine on another smartphone without any data connection problem?
2- Check the APN settings. Consult your service provider for the proper parameters.
3- Check for the baseband version? Try to flash another baseband...

[Q] network problem (very strange)

Hi guys, first of all i made searches and etc. and found nothing, this is very strange issue,
i have an s4 (I9500) and cell network is not working well. in E mode (i mean 2G) all internet voice and texts are working as should be.
in combined mode, if internet open then no network, or sometimes E with data but no 3G anyway. when internet disabled all is good.
in WCDMA mode, if internet is open, then nothing no internet, no voice no text. when internet disabled all is good again.
strange thing is i can use 3G very different way.
check 3G or combined mode first
make a call
after connected call open network data ( internet)
in a few seconds i have 3G internet. but if call ends no data again and after while no network either.
for troubleshooting in 3G mode before signal lost i see H or H+ sign on my phone but only up arrow shows no down arrow i think that mean 2 thing
1- i send a request to carrier but no returning
2- i cant send a request but phone try to send.
it was the same in 4.4.2 firmware, now i have 5.0.1
i try to patch modem with other firmwares modem files but i could find only 4.4.2 modem files. and tried all of them but no luck
so i want to use 3G mode, my phone has warranty but glass broken and in my country it is avoid warranty.
i have no box jtag or z3x box only have cwm mode and odin with usb. so is there any solution to my problem.

Factory reset your device then. This look like hardware problem anyway

I already tried that too, factory reset, clean to install New rom, and no luck...
Looks like to me software problem too but i cant fix it.. Thats why i choose title as strange i dunno what to do now..

I think im having the exact same problem, it has been like this for the past 3 months. Unable to find any solution. Tried pretty much everything. The problem started 3 weeks after I installed cyanogenmod. Flashed back to stock rom but it didnt fix it.
Let me try to explain it:
I ONLY got internet + a normal cell signal when im on GSM mode.
As soon as I switch to WCDMA - WCDMA/GSM or LTE/WCDMA/GSM I dont have any internet or a cell signal, leaving me with the only option which is GSM, but that gives me Edge internet which is really slow.
The things I tried so far:
- Different ROMS
- Stock ROM
- Updated my APNs manually and automaticly
- New sim card
- Opened my S4 to check for any damage or water damage, everything looks fine!
I tried my SIM card in my friends phone, I got perfect 4g then.
Im starting to believe its a hardware problem

No service

Hi,
I have a problem with my brand new Galaxy S7 edge. It's a European model, unlocked, bought in the official Samsung store. It was working fine but yesterday it lost service for a while. I switched it in and out of plane mode and service was back. Today it suddenly lost service and nothing seems to help. Tried plane mode, factory reset, changing network settings. Sim card works fine with my old galaxy s5. IMEI and serial number are correct. Any thoughts?

Thank you for a fast reply! Is there any chance that it's a software issue that I could resolve myself?

We have the *exact* same problem over at android-hilfe.de
I've been dealing with this issue for over a week now, latest update from two days ago didn't help. I reset the phone, switched SIM-Cards, swapped SD-Card etc. Problem persists.
NO service out of the blue.
I guess there is no way to fix thix, and I'm entirely sure more people have this problem, but they often don't notice because they are connected on Wifi.

Exactly, I haven't noticed it at first because I was online all the time. It looks to me as it's a problem with the gsm module in general as when I remove the SIM card the phone alerts me that the card has been removed so it probably sees the SIM card.

I don't know what's going on, but I see many people mentioning the exact same problem. If this happens again I'm giving the phone back. It seems to help if you switch from LTE/3G/2G to 3G/2G - but I depend on the LTE connection and it's unacceptable to me.

In my case nothing seems to help. It permanently has abosutely no service.

I've just had it die on me again. No chance I'm bothering with this any longer. There are really many things I like about this phone, but the 6S Plus has one unbeatable advantage: it works!

I've done one more test. Even emergency call doesn't work.

I have this no service problem as well please let me know how do you fix it?

How did you end up fixing it?

i have the same problem on a used s7e that i bought. i tryed with reflash it with pit etc etc and nothing helps

My T-Mobile S7 edge just had its radio bite the dust as well I guess. Phone was going slow so I rebooted it then I got no service. Rebooted a few more times, new SIM card, factory reset, software reload with SmartSwitch... nothing fixed it. I'm now 3 for 3 with Samsung phones that have mysteriously crapped out on me for no discernible reason. Not impressed.

Could be APN, I flashed a custom ROM on my phone and then it receives signal but says (and acts like) no services. Resetting APN put it instantly back to working. It can be found in Settings > Mobile Networks > Access Point Names > Reset to default (or find the APN setting for your carrier on the internet/official website, then add & apply)

Radio issue NO 3G?

Hey guys,
I've been fighting with this all day and its time to ask for opinions.
I recently received my phone back from the repair center to fix some serious cosmetic damage. Before sending it there I verified that everything was working properly.
The problem I am having now is that when I turn on the phone, it connects to LTE. I can SMS and use data briefly.
If I try to make a phone call or after a certain amount of time the mobile network will drop to either "no service" or "emergency calls only".
I have tried factory reset, clearing cache, original factory radio/bootloader, new factory radio/bootloader, N preview. No change.
Any help would be greatly appreciated.

Try this settings , other networks, mobile networks, network type change that to 3g then back to lte see if that helps

If I put it on 3G it only shows "no service" or "emergency calls only". I tested my SIM in another phone and it works fine.

Have you changed any settings in the secret dialer menu? I had this same issue and that's where my problem originated. Installing Chroma rom fixed it for me. I was able to switch Roms afterwards without issues.

*#*#4636#*#*? I have that set to the same as my other phone.

I haven't installed any non stock ROMs. I'm going to install chroma and see if it helps. Otherwise I wonder if they damaged the antenna during repair.

So I tried...
Flashing stock radio
Flashing original factory ROM
Flashing Chroma
Restoring. No success...
To make the problem even more interesting.... I inserted a different SIM (Rogers) I'm on Bell and it worked briefly. Got a new SIM from Bell, no good...
Any other ideas?

I unlocked my lg g6 via gc pro remotely, but I also new have issues with my data upload speed. When I do a speed test I get good download speeds but zero upload speed. It is not my provider as if I put the sum in another phone it gets good upload speed. So on data I also can't send pics

Tried a factory reset before, did not work.
I've been through T-Mobile and Metropcs with the same issue (not carrier-related issue?)
I've switched a sim card as well (not sim-related issue?)
Makes me think its a phone issue or unlock issue, or something else I'm missing.

No sir, it's nothing like that, I've already done factory reset card change all that is not, it's not problem unlock, the problem I dare say is the ROM firmware that has sprint lock
