Hello Everyone.
I am from Pakistan and here GSM network is most commonly used. I have Motorola Droid xt-907 (Bootloader unlocked, rooted, custom recovery installed). The problem is, I only get 2 to 3 bars of my network signals hardly and many often fail to receive important calls and texts. I tried different options in Mobile networks and when i select the network option (GSM ONLY), i get the error: "No GSM/UMTS networks were found. Would you like to switch to the global mode?" On global mode, i get very low signals and GSM is not activating.
Anyone of you know about this problem and how to solve it? Please help me..
Waiting for your positive response

Hi experts,
Very frustrated with the SGS phone GT-I9000 I bought a week ago. I keep getting "Data network not available" while trying to make merely voice call (in area with poor signal).
However, I have no problem making call using old Nokia phone with the same SIM card.
The GT-I9000 was upgraded to Froyo 2.2 (DXJPE) lately.
Anyone encountered similar issues? What's wrong with this Android phone, modem issue?
Regards,
Void
That new i would return to seller and get them to check phone under warranty .

i got the same problem after upgrading to froyo, im from Panama, but i flashed my device following some UK guide, so i flashed it with another CSC, so if you did so, we both lose our network settings, so you have to set up the APN manually.(thats what i read) but i did so and i still cant make calls nor receive 3G
It happens on EDGE. Make sure you've selected the network to operate in WCDMA only..
Switch the Wireless and network -> Mobile network settings -> Network mode to "GSM only" or "WCMDA only" but doesn't resolve the issue.
However, I notice when the problem occurred, the Setting->About phone -> Network showing "Unknown" but the Signal strength seem to be OK, fluctuating between -87 dBm 13 asu (with 4-bar) and -111 dBm 1 asu (2-bar )
Probably, SGS transceiver/modem is not as good as Nokia E71.
Anyway, I guess I can only use this "smart" phone in city area.
in my case the problem was the orange phone card. i have changed it.
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?
My i9505 only connect to GSM network (Only 2g mode) After switching to auto connect (2g and 3g) mode or 3g only mode, phone doesn't register on network. (but showing some of signal bars) emergency calls only. no Data.
When using WCDMA only mode, some time phone showing H sign and connecting to Data network for 1 or 2 min. But again switch to emergency calls only
On 2G only (EDGE) mod phone work perfectly DATA and Voice calls.
Phone has original IMEI and new KNOX boot loader
I've tried the following tasks : not fixed the issue
Changing stock rom to from 4.2.2 to 4.3 and 4.4.2
Flashing custom roms (Slimkat)
Flashed Modems : ModemXXUEMFK_BMH1, I9505XXUEMKE-MODEM, I9505_ZHUDMH6_MODEM, I9505_DVUBMG1_MODEM, I9505XXUEMK9_MODEM and more...

could u fix it? method pls
Is your phone carrier-locked?
Because certain phones can't access 3G/4G if it's carrier-locked.
Where do you live and what service provider do you use? Try changing between service providers to see if you can access 3G/4G with one of those providers.

Hi guys,
I am with Freedom Mobile - Canadian provider. I've purchased the phone from Amazon, - US version. Connected it yesterday. Worked fine, but had no LTE. I played with some settings and now I ONLY have LTE and cannot make voice calls. Whenever I try to make a voice call phone is trying to connect, but fails in around 30 seconds telling me Network is not available for voice calls.
Was wondering if anyone experienced similar problems.
Additionally, would you mind sharing settings under the below 2 menus, that work for you for Freedom Mobile:
1. Mobile network settings -> "Preferred Network type"
2. In the hidden menu, dial: *#*#4636#*#* under "Phone Information" what is your's "Set Preferred network type" selection?
thank you, I would appreciate your help.
Flash modem from your OS once again. My collegue had similar problem. Tapped something what shouldn't be tapped and disabled 2G, 3G networks. Does Freedom Mobile support VoLTE technology? If not then you will not be able to call via LTE.
Hello there. So i just got a Nokia 6 and i'm having the same issue. Can't make or receive calls but i can send and receive texts and can use the LTE service for data. So i'm supposed to flash what exactly? And any resources i can refer to for the flashing process? P.S: I'm a noob
hello!
I am trying to set my network mode to WCDMA because I want to use data and receive calls on the same time since my carrier hasn't enabled VoLTE (that's another story...) but I can't!
The option is there, settings, more, Mobile networks, network mode, i make the change to "GSM/WDSMA auto" but it won't stick! If I go back and come again to this menu, the option is reverted back to "GSM/WDSMA/LTE auto"!
There is no luck either with the LG hidden menu, *#546368#*870# , it says "Connection problem or invalid MMI code".
Could this has to do with my modded kernel?
Any other ideas?
Here is my setup right now:
LG G6 H870
Android 7 Nougat V11i-EUR-XX
Melina kernel 3.18.62-melina-rel7_2017.12.31_uber-6.x_STOCK_zefie
Thank you in advance for your help!
That is a GSM phone. You cannot simply switch to CDMA. Different hardware.

what?
If i know that correct, WCDMA = 3g, right?
I want my device to be locked to 3g only, not 4g, because when I receive a call, it drops from 4g to 3g and I lose my internet connection, which is really frustrating if you are in the middle of a video call!
