I'm preparing to install Russian rom from xiaomi . So you advice me not to do

I'm pretty sure that it is a GSM only phone. The W-CDMA listed in the specs is actually UMTS, the competitor to CDMA2000 and the 4G standard used by GSM networks.
What network are you trying to connect to?

Yes it is CDMA2000 EVDO.
When I insert *#*#4636#*#*
I have cdma among networks' list.

I don't think it is going to work. Which cell provider are you trying to use? In what country?
Most US reviews of unlocked phones specify that they will only work on GSM networks like T-Mobile.

I'm from Yemen Arabia. My network is Yemen Mobile Telecom.CDMA2000 3G EVDO.
and the rn7 reads the sim information like network name and services on the sim .

I have no idea about Yemeni carriers, sorry. Have you tried calling them?

Hi I don't know if this helps anyone and I know this is an older post but I think I found how to turn CDMA on. developer options enabled, go into about phone settings and tap "internal storage" until it opens up phone info. Choose the sim slot and there you can set preferred network to CDMA only or something like that. I don't know much about mobile network but I saw that CDMA setting in there.

That menu you get after clicking on internal storage is the same as typing *#*#4636#*#* in Phone. I've tried changing it to CDMA only or LTE/CDMA but nothing happens, the UIM card is recognized but it can't log on to the network.
More info: the Global Rom version of the phone only works with CDMA carriers that have LTE data and VoLTE voice. It does *not* work over CDMA 1x or EVDO. I had to swap a new China Telecom UIM to get VoLTE working.

Hi. I bought Redmi Note 7 Pro from aliexpress with global Rom. It does not connect to my carrier in Poland. The status of the sim keeps changing from no service to emergency calls only every 2 seconds. Is there any way to fix it?

RN7 not work on the network CDMA.

Is there anything I can do or should I return the phone?

WDCMA/GSM
WCDMA only

Does this mean that the phone wont work on lte? can anyone else confirm if they have the same phone.
Thanks,

It's there but you have to unlock and root the phone. flash a modem to enable it.
That is not true, you do NOT need to root the device or modify it in any way to get LTE to work simply plug in an LTE sim once the device is unlocked and it will pick up the network. I purchased my Note 3 from WINDMobile on friday and tested a Rogers SIM in the device to check out LTE compatibility it picked it up no problem and I can pull about 25Mbps on the Rogers LTE network in Calgary

Moto x pure not registering onto GSM sim

Hi,
I have a Moto X pure 16GB (xt1575) bought from USA. I used it on multiple carriers in USA and it worked fine.
I am on a visit to India, where I intend to use the phone for couple of months.
I tried with these networks:
CDMA sim (Operator Tata Docomo) - Network gets detected and sim is operational
GSM sim (Operator Airtel) - Sim is detected but doesnt get registered onto network
GSM sim (Operator Reliance Jio) - Sim is detected but doesnt get registered onto network, seems some problem with Jio network, they have additional things for VOLTE to work.
So, I am pretty sure, the handset is fine, changed the network settings thru the secret menu phone info, to LTE, GSM to what not. nothing works for Airtel Sim.
The bands do work in India and are compatible.
Any idea's what more can I do?

The rom is stock and generally dont fiddle around with the ROM's as I have never done it.
Can try it if nothing works.
I am noob, a procedure would be helpful or a link to it.
Thanks.
Apn?

It does show the Apn, but the gsm service shows as unknown and network type as unknown.
Any users from India have any suggestions.
AIrtel and Jio work fine on the Moto X since many users here have and are using it with them, except the VoLTE part of Jio you have to use the Jio4voice app to make/receive calls.
Have you tried going into the Phone app, dialed *#*#4636#*#* and gone to Phone Info and changed "Set preferred network type" to something different?
Also, I think the Jio SIMs require a very specific registration process, going through several apps to get them working... check with a local shop.
Here's some snapshot from the menu screen and network finder applicaton.
I know the ans to this soln
i am a jio user and basically the problem is that mxp supports volte but the frequency is the main issue.. due to unmatchable frequency the volte ain't activated for jio
u can try t&t and Verizon sims volte is working on them but jio frequency is not up to that mark as mxp but an official nougat update might help the frequency to maintain and volte might get activated.....
so we need to wait for official nougat update only... trying romcwont work..
screenshots are here

Thanks for the response, I will wait for the Nougat update.
Does the same apply for Airtel also ? It shown network type as unknown.

No Global Network Mode

I have a factory unlocked S8 I just recieved that I've been using on Straight Talk(verizon network) and that's been working fine but I wanted to test the reception of t-mobile in some places and I can't get anything to work. I have a Flash Wireless sim that I've used to at least see if I have service on other phones but I get nothing on the S8.
In Network Mode I only have the option for LTE/CDMA or CDMA. No Global or GSM options are even listed. Does this have to do with the SIM card not being properly registered? I would think I would have a Global option regardless of SIM I put in it.

I have the same problem. I'm on MetroPCS and I bought a Galaxy S8 used on Straight Talk before. I can't make any phone calls, but I have LTE and SMS works just fine. Does anyone else experience the same issue? I really appreciate any help. Thank you.

Flash Verizon S8 with european firmware

Hi guys,
I bought a Verizon s8 in the states and wanted to use it in Europe. I live in the Netherlands, so I swapped in my Vodafone some instead of using the Verizon Sim and everything works fine besides mobile data. I can not change the APN settings as they are locked. Carrier says it's Verizon though it's using the Vodafone Network.
So I was wondering, can I flash the firmware with a european version to get access to the APN settings and remove the carrier lock?
Best
the s8 verizon is not locked just put your sim card in and thats it.you cannot flash international rom on the us version odin wont let you it will fail even if you somehow made it it will brick the phone.the reason is because the us s8 version uses snapdragon chipset and the s8 international version uses exynos chipset they are completely different.
the option you have is to flash the us unlocked version to the verizon s8 i did on mine i have verizon also.

I was wondering is there a way to add more international languages on my s8+. I have managed to change parts of it but on menu and while scrolling in facebook it doesn't recognise i.e some norwegian / turkish letters and doesn't switch language in parts of menu.
The model i have is G955U1 ?
Thanks again.

Tv87, I am in the exact situation as you. Have you resolved your problem? If so, what was the solution?
I just moved to the Netherlands a few weeks ago and switched my S8's SIM Card from Verizon to Vodafone. Everything worked fine except for mobile data. The Vodafone rep told me that my APN settings were grayed out / locked; therefore, until they could be edited, my phone would not receive mobile data.

They are not locked, the phone still thinks it has a verizon sim and that's why you cant edit the settings, do a complete factory reset.
And anyways, even with editable apn settings you wont get lte, because your s8 is lacking the european lte bands.

What makes you say that?

Says:
"In Europe, most carriers base their networks on bands 3 (1800 MHz), 7 (2600 MHz) and 20 (800 MHz). China, on the other hand, uses a whole different 4G LTE standard - while the Western world has rolled out FDD-LTE networks, China and large parts of Asia use TDD-LTE."
And several places online show all those as being supported on the g950u.

I said that because most phones that verizon sells dont have the lte bands for europe, but according to frequency check, it is compatible !
Sorry about the error

I did a factory reset while my Vodafone SIM Card was in the phone. I am now getting the following message:
Sorry, we're having trouble activating your phone.
If you're moving your phone number from your old phone to this one, make sure your old phone is turned off.
In addition, I get the following message on the very next screen:
You can set up your phone using Wi-Fi, but you won't be able to make or receive calls until your phone has been activated on the Verizon network.
Is there anyway to unhinge my phone from the Verizon network!? Before I left the United States, Verizon assured me my phone was not locked to their network; however, it appears to be based on the messages received after factory resetting my phone.

What you can try is to flash the USA csc instead of the VZW one that you have right now.

Issues with LTE on Unlocked Sprint Note 4

Hi all,
I've been having a Sprint Galaxy Note 4 that is unlocked. I bought it unlocked already. My mobile service provider is T-Mobile. I have an unlimited plan with them. The issue is that the Note cannot connect to LTE network. The only option available for me to access the internet on the go is the GSM/UMTS option under the network mode settings. Using this option my phone can only connect to a 3g service that is painfully slow. If I try selecting the CDMA or LTE/CDMA option under the network mode settings the Note will not get any service at all as if there was no sim card inside of the phone. Therefore I can only use the GSM/UMTS option. Is there a fix for this or am I stuck with 3g service on this phone? Please ask me questions if you have any that will help me get to a fix. Thanks :fingers-crossed::fingers-crossed::fingers-crossed:

I believe the LTE bands in sprint CDMA/VERIZON CDMA are different. they are not compatible with T-mobile because T-mobile required completely different LTE bands and they are locked in sprint phones and they cannot be unlocked.
If you have N910V/N910P You will only get HSPA/HSPA+ 3G/3.5G with T-MOBILE/AT&T network.
My best suggestions will be you can swap your sprint with T-mobile note 4 because N910T has more LTE bands unlocked then any other note 4 models actually more bands then international models too.
