This is for a friend with this specific request. BUDGET: I was told it has to be cheap. I assumed it to be below 10k but it actually could be much lower Has to be new. Should be good and reliable, she's coming from a nokia, If I give her a sub-10k android recommendation I will most likely not survive the following day. I want to know if there are any Nokia options around 5k or upto 10k. Other brands if any should be reliable and not lag. Presently uses a Nokia feature phone S40 series, I think was 5k or 6k CRITERIA: Has to be compatible with whatsapp. There could be better messengers out there but this is the specific request. That is all I was told. Kindly make some suggestions. Thanks Any brand is ok, Nokia, Samsung iphone , etc. Any OS is fine as long as it's easy to use and does not lag.
