This is cheap product then other brand same level product,
the network stability is not up to the mark, but the you can’t expect to much in so much low price.
aapko kahi na kahi samjhota to krna hi hota hai, sometimes network gayab hi ho jate hai.
kabho net accha chalta hai to kabhi bura.
so I can say that it is good for low budget user, but if you wanna better feature and service please don’t go with it.
