>There is still a huge population which wants basic phones as a backup atleast.

I don't just want a basic phone as a backup. I want real sim card portability/functionality. I want to have a smart-phone when I need it, and I want a lightweight, rugged, long battery endurance phone I can pop the sim card into for activities where I'm willing to compromise features for durability (or speed/ease of use).

> The senior citizens even though have migrated to smartphones stil are in the dire need of a durable small phone.

I still can't believe that nobody has done this. I attribute it to my cynicism about dealing with telecom middlemen (data providers).
