Thanks to Indians who bought this.
True...Realme have highest signal range...This phone is made for rural areas and for inside building rooms...One thing i must say about Realme which i noticed today itself.
Its Network adapters and radio is awesome.
I was sitting in a meeting room. Niether my iPhone nor Samsung S8 was getting 4G reception but one of my colleouge who was using Realme was getting 4G and hence i have to connect to his hotspot.
