Hi Sifu, would like to have some recommendation as below:

1. Brand: Any
2. Budget: RM600
3. Specs: 4GB & above, dual sims 4G.
4. Type/Size: doesn't matter
5. Usage: Women use, good battery life hotspot for Google class, good camera.

Current using Samsung J7, only 1 sim can be 4G, and another have to be 2G. Recently my area Maxis 2G become very weak, always no signal.
Been survey on vivo Y20, Oppo A31, redmi 9, Realme 5i or Huawei Y.

Any recommendation or comment?
