using umobile P70 right now :

1. data wise no problem (KL area) and light usage is good (4G full bar indoor can get u like 100kb-5MB download) not consistent
2. network coverage so-so but can be frustrated at certain area especially north places like perak,penang,kedah
3. not really good speed inside public transport(bus/train/highway)
4. data add-on is expensive
5. use paid mangarock app in android and ios for auto download favourite manga
conclusion,go back to maxis
