unlocking Yureka?

can we unlock Yureka to be able to use a SIM card from a different carrier? like EMTEL?

anyone? any inputs?

YU Yureka isn't locked to any particular carrier.
Yureka supports the following bands:
2G bands GSM 900 / 1800 / 1900 - SIM 1 & SIM 2
3G bands HSDPA 900 / 2100
4G bands LTE band 3(1800), 40(2300)
Emtel operates on:
2G Bands: GSM 900
3G Bands: W-CDMA 2100
4G Bands: LTE 1800
So there shouldn't be any problem.

Thank You so much Titokhan

It also supports B2, B4, and B17 LTE
LG G4 (GSM)

Really good feature and hope it appreciate people a lot.

How will International Version work on T-Mobile US?
I referred to - http://en.wikipedia.org/wiki/T-Mobile_US
LTE:
B2 - 1900 MHz - YES
B4 1700/2100 MHz AWS - YES
B17 No
Wifi calling and VoLTE will not work? HD Voice won't work either?

Model LG H815? Should be ok for ATT LTE, it seems
hmm...

So how will this version work on T-Mobile US?
I have less need to T-Mobile wi-fi calling or HD Voice.

Tmobile 1900 3G refarming status

I have a 3G GSM modem for sierra wireless. It supports 850/900/1800/1900 GSM/EDGE frequency bands and UMTS B1/B2/B5/B6/B8 frequency bands.
Is Tmobile's 1900 MHZ 3G refarming completed in most parts of NYC and USA ?
Will I be able to get a 3G signal on my modem in USA (primarily all boroughs of new york city) and be able to upload and download data despite not having the B4 frequency band ?
I believe B1 is 2100, B2 is 1900 , B3 is 1800, B4 is 1700, B5 is 850, B6 is 800, B7 is 2600 and B8 is 900.

support for t-mobile 3g & 4g?

anyone working on facilitating >2g on T-Mobile network with the Xiaomi RedMi Note2?
Per mi.com/note2/specs/ it appears the device will support:
4G Network TDD-LTE (B38 / B39 / B40 / B41: 2555-2655MHz); FDD-LTE (B1 / B3 / B7)
3G network TD-SCDMA (B34 / B39), WCDMA (B1 / B2 / B5 / B8)
2G network GSM (B2 / B3 / B8)
Whereas T-Mobile support site indicates it utilizes these bands:
4G via: Frequencies: Band 2 (1900 MHz), Band 4 (1700/2100 MHz), Band 12 (700 MHz)
3G via: Frequencies: Band 4 (1700/2100 MHz)
2G Frequencies: Band 2 (1900 MHz)
Or for starters does anyone know if this type of mod is even possible given the modem chip used in the device?

Very Confused On How Bands Works

I'm comparing two different models of the S10. The T-mobile carrier model vs the Factory Unlocked model. Found this link for a direct comparison.
https://www.techwalls.com/samsung-galaxy-s10-model-number-sm-g973-differences/
If you compare the two under band support, you get some really confusing numbers and abbreviations which I will list off below.
S10 Factory unlocked band support;
===============
2G GSM: GSM850, GSM900, DCS1800, PCS1900
2G CDMA: CDMA800, USPCS1900
3G CDMA: CDMA2000, EV-DO: 800, 1900 MHz
GSM 3G/3.5G: UMTS, HSPA+: 850, 900, 1700, 1900, 2100 MHz
4G LTE: 1, 2, 3, 4, 5, 7, 8, 12, 13, 14, 17, 18, 19, 20, 25, 26, 28, 29, 30, 38, 39, 40, 41, 46, 66, 71 Bands
=======================
S10 T-Mobile Carrier version:
======================
2G GSM: GSM850, GSM900, DCS1800, PCS1900
3G UMTS: B1(2100), B2(1900), B4(1700/2100 AWS1), B5(850)
3G TD-SCDMA: B34(2010), B39(1880)
4G FDD LTE: B2(1900), B4(AWS), B5(850), B12(700), B66(AWS-3), B71(600MHz)
4G TDD LTE: B46(5200)
=======================
As you can see, there are some terms or numbers missing from one model that are on the other, and vice versa.
Can someone please walk me through what all this means and what the differences are? I want to be able to use Tmobile on the unlocked model without losing any band support or network coverage/quality.
Thank you!

alos curious
I am also curious about network support on various types of same model.
EX: Redmi K20 and MI9T are the same phones, the only difference is supported networks.
K20 doesn't have B20 network for example.
I don't understand why, since both devices have SD730 processor which has x15 Modem inside.
Does this mean that some networks are disabled by software?
Would kindly appreciate the answer...
