I decided to test his method, and put everything in order at the expense of Band 20, and its presence or absence in different models .
Two models will participate in the test:
Redmi Note 4X- 2016101
1) Redmi Note 4X- 2016101
Redmi Note 4 Qualcomm Global -2016102
2) Redmi Note 4 Qualcomm Global -2016102
The test will be conducted with two SIM cards:
Beeline - The LTE frequency at which the 20-800MHz Band operator operates
Geocell - LTE frequency on which the operator operates Band 3-1800MHz
Before you carry out the test, and I tried to find out the frequency at which the two operators work. I called each of the operators in the call center and asked for clarification on what frequencies LTE works
their network. Because in our country mobile network operators do not disclose this information - the operator simply replied:
"That would use our 4G internet needs the support of the respective frequencies by the user . "As expected - it turned out to be the frequency
Band 3 at
Geocell and
Band 20 at
Beeline . The frequency of the test experiment was expelled operator
MagtiCom , Since it has the support of the operator as
Band 20 so and
Band 3 .
Let's start! I insert a Beeline SIM card in Redmi Note 4X-2016101
I wait for 5 minutes to determine the network ... And here is the result
As you can see Redmi Note 4X 2,016,101 identified only 3G or 3.5G, more I do not got him. I waited not much, however the previous result, Redmi Note 4X 2,016,101 does not see Band 20. Now insert the SIM card into the Geocell Redmi Note 4X - 2016101
In this case, just pick up a 4G network, even not have to wait
We conclude, Band 3 Redmi Note 4X - 2016101 running, while Band 20 has not earned.

We perform the same manipulation Redmi Note 4 Qualcomm Global 2016102 I insert the SIM card of Beeline in the Redmi Note 4 Qualcomm Global 2016102
And as you can see Redmi Note 4 Qualcomm Global 2016102 immediately picked up 4G from Beeline
Now insert the SIM card into the Geocell Redmi Note 4 Qualcomm Global 2016102
And here, too, everything is in order, Redmi Note 4 Qualcomm Global 2016102 immediately picked up 4G from Geocell.
We conclude on account Redmi Note 4 Qualcomm Global 2016102. The model works as a network
Band 20 from
Beeline And network
Band 3 from
Geocell .
We conclude the account Redmi Note 4X 2016101. The model works only in the 4G network of Geocell, ie Band 3. Cmelo declare that Redmi Note 4X 2,016,101 no support Band 20.
Firmware on devices are the same
Total: This test I wanted to show clearly how I tested two different versions of the device for the presence of networks, without any programming and rue. This post I end the discussion on billBand 20 and its presence or absence. In addition, I want to make it clear to all those who think that Band 20 can be unlocked by software. It is not possible, because the required hardware-level support. Those who do not want to believe this test without screenshots from the app Network Signal Guru and the like - it's your choice. This post is not written with the intent to deceive someone. If anyone needs further proof, the cap Fill your tests. I think it was all clear and understandable!
I think you can add a cap!
