What's the phone for me? What's the data deal for me - in South Africa

I have been asked... What's the phone for me?  What's the data deal for me?

I have taken out contracts - but only if the price of buying the phone plus data  plus airtime makes sense.  Otherwise, it's buy the phone for cash, and go PrePaid for me.

I like Samsung J70 Pro, and now their A71 - Telkom FreeMe deals were gr8 until 1st May 2020 when Telkom reduced their value so much so that I cancelled getting the new A71+FreeMe 1GB.  

I decided to stay with my J7 Pro with its "expired" contract - which still has the "old" FreeMe 1G plan (free 3,000 Telkom to Telkom minutes (cell and landline), and 1GB data and 100 any network minutes included).

I also like Xiaomi phones -  Redmi 4X dual SIM phone was a gr8 phone and still working well.

All phones in my house are dual SIM.  I purchase the following pre-paid deals for my family - depends on their use:

• 365 days validity: CellC data 10GB for R599: https://www.cellc.co.za/cellc/get-databundles  (works out to 6c per MB)
• I am also considering moving them to Afrihost AirMobile (PrePaid): https://www.afrihost.com/airmobile/prepaid# where you get 2GB for R69 on MTN - if you login to their app once a month.(this works out to 3c per MB)Data lasts for at least 60 days.
