I'd suggest to go for SE (SonyEricsson) phones. They have excellent UI that attracts (and easy to use for) even someone aged 55+. As your budget is limited to 10K, I'd suggest to go for SE Zylo. It doesn't have touch screen/wifi and have low battery standby time. Actually, every other phone does have some negative points to talk about in 10K range. It costs 6.2k.If you are really looking for a (capacitive) touch screen phone, then I'd recommend SE txt pro. It costs around 7.4k. It has almost everything for an elderly person. Touch screen/wifi/slider qwerty keyboard, etc. Again battery standby time is the issue in this model too. 🙂 But for someone who doesn't make a lot of calls, the battery should come for a day, at least.Hope this helps.
