I dont have any budget issue as such but I dont want to spend much as I already have a primary cell so as less as possible, I want this cell for secondary use which I can use while travelling to other cities, to avoid getting robbed of expensive cell, already happened once.
So it should be able to run normal apps like whatsapp fb, telegram, careem etc without lagging and be 4G supported and can act as a hotspot.
I saw an ad of redmi go with 1gb ram for 11k, not sure if that can handle this much.
