hi try this code *#2683662#, then go through the 2nd menu option and you should find a menu option for band selection in there somewhere.

[Q] IM-A890L Hidden code RF band selection help!?

My phone is the Vega Secret Note. The phone does work, and I am able to access LTE 2100 here in Canada with it.
I just want to double check if there isn't any bands that could be locked... I've read somewhere on Naver that it does support LTE 2600. And since LTE 2600 is LTE MAX here it would be my prefered choice if it's available somehow on my phone. I'm wondering if it could be a hidden band that needs to be selected....
*#*#4636#*#* Does work, but there is no band selection on that menu
I am trying to get RF band selection menu.
I know Samsung usually uses : *#*#2263#*#*
But there is limited info for Vega phones on here and around the web....
the closest I came to was using thise code # # 7593 # but there is no LTE band selection menu.
I found this thread assuming since these codes are also from Vega that most would work, but only 2-3 works ...

Thanks for your help or hints!
What happens if you switch 4G data from sim 2 to sim 1? Will that other network indicates correctly then?
I think they removed it in latest update?
I used to see 4g icon even when connected to wifi now it disappear when on wifi.
So maybe they disabled one when the other is active.
Between which region you got?
It depends by region. Don't know why...
There is system setting in local.prop, so it can be changed if you have root and cust partition read/write.

Is it Possible to Enable LTE Band 1 (2100Mhz) in Moto XT1225?

Is it Possible to Enable LTE Band 1 (2100Mhz) in Moto XT1225? I have tried editing NV values in 06828 and 06829 which enables LTE Band 1 but, it's of no use. I still couldn't use LTE Band 1. Vodafone India uses LTE Band 1. Looks like it hasn't been enabled. Is there any other way or chance to enable it? I'm in crDroid Android based on CM14.1 with @bhb27 kernal.
My ROM:

After flashing those values I visited Vodafone store and a person there showed me the their CRM. the values which I wrote are seen in their CRM.
And I have a doubt.
I visited Vodafone Store and confirmed that they transmit 2G in 900Mhz, 3G in 1800Mhz and 4G in 2100Mhz in India.
My phone operates in 2100Mhz Band when I select 3G, and 1800Mhz in 2G. And no signal in 4G.
Is it possible to operate in such bands? Or since my phone as 2100Mhz support in Both 3G and 4G, the 4G is being used as 3G thinking it's 3G?
Please Help.

What is your model number? Is this a 5G Plus, or Stylus, or...?
We have device specific sections that you'll probably get more help in, so if we know where this thread needs to go, we can move it for you.

It's regular moto g 5g 2022 that is the model name.
You should have a toggle for 'Allow 5G' that will do what you want. If not, use the dial code *#*#4636#*#* and pick an appropriate config under Phone information -> Set Preferred Network Type that does not start with 'NR'.

Awesome. Where can I find the breakdowns of each network type. Which one is 3g. I think 4g is LTE
On the TMO network 2G is GSM, 3G is WCDMA, LTE is 4G, and NR is 5G. CDMA/EvDo would be for Verizon 2G/3G. TDSCDMA was developed in China so you won't see it deployed in the US.
