hi, I m from India. I would like to buy the S21 ultra snapdragon variant as in India only Exynos variant is available. I have few doubts, so please clarify them.
1. I understand that this is Hong Kong Variant. Hence the serial no would be SM - G9980ZKGTGY.??
SM-G9980

2. Google services will work ??
Yes. 

3. What about 5G? as of nw, in India 5g services arent available. Will this mobile get a 5g service in the future? I cross-checked with Samsung exynos variant 5g bands and HK Samsung snap variant 5g bands. I could see some similar 5g bands. I hope using this HK variant in India won't be an issue when 5g comes to India.

Here is the supported Bands.

4G bands 4G FDD-LTE: B1(2100),B2(1900),B3(1800),B4(AWS),B5(850),B7(2600),B8(900),B12(700),B13(700), B18(800),B19(800),B20(800),B25(1900),B26(850),B28(700) 4G TDD-LTE: B34(2010),B38(2600),B39(1900),B40(2300),B41(2500)

5G bands 5G Sub-6 FDD: N1(2100),N5(850) 5G Sub-6 TDD: N41(2500),N78(3500),N79(4500)

4. How long it will take to get delivered in India?
