I've had a couple of affordable smartphones that I used for my overseas SIM cards. Tried the lower-end Samsung ones but the camera was not so sharp. Xiaomi is very value-for-monies as a phone (I have 4 of these) but the Malaysian SC sucks big time. If something broke down, they would require a month or two to order the spare parts in (they don't stock them enough locally, and that was why I started with 2 Xiaomi Mi4i phones but bought an additional 2 when the first 2 broke down and had to be kept at the SC for 1-2 months). Huawei has been faring very well thus far- I had the P8 and recently started using P9 too, as the Leica camera was pretty good. For RM1k, I would recommend you look at Huawei ones.
