Nokia 110 & 112 Dual-SIM phones launched in India

In recent years ,Thare are more number of entry models are launched from nokia than their sold items😨.
Why not they are just concentrating on Nokia 1100 type device. like a weather proof phone, cheap and allrounder.
If I am not wrong these phones are for village people who just want call facility in their phone. The dual sim phone got boom but now people are just getting sick of dual sim, and returning back to single sim as it is more managable less costly.
