I have this problem "Your SIM card does not allow a connection to this network"
at the top see Red Cross icon similar as:

It usually means your phone is SIM locked to a specific carrier, and you'd need to SIM unlock it if you want to use a different carrier's SIM.
If you have a Verizon XT1060, or a GSM Developer or GSM Unlocked XT1053, it shouldn't be SIM locked.
If you have a Sprint or Republic Wireless variant, there is a thread for SIM unlocking.
If you have any other 2013 X, you'll need to find an online source to buy the SIM unlock code, unless you meet your carriers conditions for them to give you the SIM unlock code.

Where did you get your handset and on what network?
Sent from my XT1058 using XDA Free mobile app

Model XT1052 network bands supported on my area (asia) . ( GSM / LTE 1800 / 2600 )

I do not know what happened, maybe because flashing Root is not compatible
previously working well,suddenly appeared after receiving the first call

i try factory rest from bootloader & factory reset from recovery
and this trick by code *#*#4636#*#* radeo on/off etc...
All attempts did not succeed

[Q] Frequency Band messed up

Hey guys,
it seems like i messed up my frequency band on my i9305.
i installed an app to change my network status to WCDMA only as the signal at my working location is very low and my phone automatically switches to edge (which i dont want it to)
The app itself is just a shortcut to the service menu.

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Changing the network mode worked fine, but i accidently tapped the menu button AND changed the frequency band to USA while holding the phone in my hand without watching the screen.
my question is:
how can i change it back to EURO band?
as you see, there is no option for that.
i switched the preferred network mode back to LTE/GSM auto (PRL)
as you can see on the first screenshot, it shows -81 dBm 59 ASU for the signal strenght.
so for me (im a noob at this) it seems like the phone actually recognizes there is a network but it doesnt connect to it because it is set to USA band. May that be right?
However, i need to know how to switch back to EURO band, flashing another modem didnt help at all.
can i do that with adb for example?
(com.android.settings.BandMode) << scratch that.... am start -n com.android.settings/.BandMode in adb gives me the same options of course (USA Band, Cellular 800, PCS 1900)
Please help me somehow
Edit: to clear things up: When using *#06# it still shows my imei. it also shows the baseband in the phone info under settings.
if i get it right that means that the efs partition is still okay.
i have no idea what could be wrong

Update:
Looks like i solved the problem.
i just flashed a lollipop cm12 rom + gapps, flashed the modem again and voilà.
I even have a better signal now due to the new modem.
After that i went back to the nameless lollipop rom and everything is still fine.

Dual SIM Note 5 Duos not receiving very good 2G signal. Can I do anything to improve?

Hi Everyone,
I have a Samsung Galaxy Note 5 Duos and reception with one of my SIM cards is quite poor. Since purchasing the phone I have come to realise that the Duos operates on 2G/3G/4G using one SIM card, and on the other it operates purely on 2G. Unfortunately 2G reception in my area is very poor, so in essence I now have a phone that doesn't work equally well for both phone numbers that it services.
My question is two fold, 1). Is there any way of improving 2G connectivity?, 2). Are there any mods / ROMs / etc which attempt to improve the dual SIM operability of this phone?
Kind Regards,
Davo

Unfortunately, it seems like this is an issue with the phone's hardware, not software. There is however a possible fix, and that would be to flash a diff radio onto your device. I'm not sure which radios would work the best, or even where to find them. But good luck!

Hi Everyone,
Further to my original post here are some screen shots from my phone -
1). This is a photo of my 2G/3G/4G (auto connect) SIM coverage at home (on my old phone, and my wife's phone I get full bars!).

2). This is a photo of my 2G SIM coverage at home.
3). This is a photo of my 'About phone'.
4). This is a photo of my 'Software Info'
As can be seen above my reception is extremely poor, particularly on my 2G/3G/4G (auto connect) SIM.
I have tried swapping 2G/3G/4G (auto) and 2G between the two SIMs. Furthermore I have tried the phone with only one SIM inserted. No matter what I do configuration wise the reception remains very poor.
Any further suggestions here will be greatly appreciated.
Kind Regards,
Davo

the same baseband ****AOJ3, the same problem here.
Problem is arising from your installed baseband model. nothing else

My carrier doesn't claim it supports Wifi calling with Xiaomi, Can I do something?qq

Hi,
I have Xiaomi 9t pro and I opened the Wifi calling (and LTE) with the codes and I see in the sim settings the toggles as expected.
I check with my carrier and they opened wifi calling option for me.
But still, there is no wifi calling icon (seems like LTE works because I see the LTE icon).
My carrier says it supports wifi calling out of the box for Samsung and LG devices, so I guess it doesn't work for me because I use Xiaomi device. If I put my sim in a Samsung device wifi calling is working.
Is there anything I can do to make it works with my device?
I'm from Israel and my carrier is Pelephone.
Thanks!

Man i had to call Hot like 5 times till i got someone that wasnt some frecha that knew what volte was and enabled it again on my phone(after they disabled it!). Keep on calling and seeing till you find someone in tech support that understands. Wifi calling works with my girls samsung note 10+ also on hot, im not sure if they enabled it for me but im waiting for next corvus rom release to test because it will have wifi calling.

Force LTE only without root access, Huawei P30 Pro

I would like my phone to always reconnect to the network once it looses LTE bandwidth.
The thing is that the provider gives me LTE for the first few minutes, but then reduces my speed to HSDPA
So what I need is an app that goes into the airplane mode for just one second and then reactivates the connection.
I found out that rooting my phone is impossible and all the apps that I tried do not work without root.
I downloaded about three different apps all claiming to provide a "Force LTE" experience.
Any suggestions on how I can achieve the goal of auto reconnecting to the network in case my bandwidth drops lower than LTE?
It wouldnt be an issue if I would be actively sitting on the phone, but I am using it as a hotspot with the phone at the window to have best connectivity.

Download this app and change the numbers I've circled in red to just "11" and reboot. You'll have loads more network choices.

It appears to me that the provider doesnt allow me to choose LTE only? Is that possible?

The method is very easy:
1. Use SIM 1 as the default connection setting
2.
You need to install this app for FREE
at Google Play
https://play.google.com/store/apps/details?id=com.teknokia.force4glteonly
pro version : https://play.google.com/store/apps/details?id=com.teknokia.force4glteonlypro
galaxy store: https://apps.samsung.com/appquery/appDetail.as?appId=com.teknokia.force4glteonly
pro version : https://apps.samsung.com/appquery/appDetail.as?appId=com.teknokia.force4glteonlypro
3. Run the application, press the SIM 1 only or Android testing button. You will enter two LTE Switcher options and also 2 Android testing options.
4. You can try all of them which support your phone.
If the telecommunication operator you are using does not support VoLTE (Voice over LTE) and uses LTE Only Mode, so regular calls will be blocked.
