Question about Mi 4i 3G bands and variants - Xiaomi Mi 4i

Official site has
2G: 850 / 900 / 1800 / 1900MHz
3G: WCDMA 850 / 900 / 1900 / 2100MHz, TD-SCDMA 1900 / 2000MHz
LTE: FDD-LTE B3 / B7, TD-LTE:B38 / B39 / B40 / B41
But most chinese sellers like GearBest.com and almost all on eBay and Aliexpress have
2G: GSM 850 / 900 / 1800 / 1900 - SIM 1 & SIM 2
3G: HSDPA 850 / 1900 / 2100, TD-SCDMA 1900 / 2000
4G: LTE 1800 / 2600, TD-LTE 1900 / 2300 / 2500 / 2600 (Bands 3, 7, 38, 39, 40, 41)
Are these different variants or do people just omit some frequencies? I am looking for one that has WCDMA 900Mhz like the official site lists. Is anyone able to test for the existence of these frequencies on their device and where did they buy it from?

T-mobile UK, will it work?

If i buy the Droid 2 Global from America and unlock it, will the 3G/UMTS work with my T-mobile UK sim.
Frequencies are: My current UK T-Mobile Pulse which of course works fine GSM 850 / 900 / 1800 / 1900 HSDPA 900 / 2100
Droid 2 Global GSM 850/ 900/ 1800/ 1900 UMTS: 850/ 1900/ 2100
is the omission of the 900mhz UMTS band a problem?

[Q] What US Carriers will this phone work with?

I am thinking of purchasing a phone that supports the following bands:
2G: GSM 850 / 900 / 1800 / 1900
3G: HSDPA 850 / 900 / 1900 / 2100
4G: LTE 700 / 1700 / 1900 / 2100 / 2600
There is a variant of the phone that supports the following 4G instead: LTE 800 / 900 / 1800 / 2100 / 2600
Which bands, if any, would work on Cricket Wireless (my current carrier). If none of them would work on Cricket, which 4G bands in particular work on US carriers?
TIA

[Q]. Need to know Model vs 3g bands used

I have been looking in many different places and could not get a decisive result towards which E8 model has which frequecy bands, especially concerning the 3G bands.
I hope one could give us a conclusive answer to this.
I myself have an M8sw chinese dual sim E8, and I still cant tell this answer wether I have
850, 1900, 2100 or
900, 1900, 2100 or
850, 900, 2100 or
850, 900, 1900, 2100
And I could not find one conclusive answer to this.
Please if someone can link each model to its bands, I would be extremely greatful.

Use Google translate, man...

What bands do the F510S/K model support?

I'm looking to purchase this f510s/k model from Amazon
But i'm getting conflicting info about the bands.
According to one on amazon:
2G GSM900, GSM1800, GSM1900
3G UMTS1900 (B2), UMTS2100 (B1)
4G LTE2100 (B1), LTE850 (B5), LTE1800 (B3), LTE2600 (B7), LTE900 (B8)
Yet this one says
2G GSM: 900 / 850 / 1800 / 1900 MHz 3G WCMA: 2100 / 1900 / 850 MHz (Band: 1 / 2 / 5) 4G LTE: 2100 / 1800 / 850 / 2600 / 900 / 700 MHz (Band: 1 / 3 / 5 / 7 / 8 / 17)
Both for the same type of phone, just different colour (would post links but the forum isnt allowing me to)
Which one is correct? I need GSM 850 and UMTS 2100 for my country's provider.
Also does anyone have this version of the phone? Does it work fine with AT&T / T-MOBILE?
Thanks
