In some region zenfone laser2 not supporting JIO 4G service or not getting JIO4G SIGNAL BAR because network band 850mhz (provided by JIO NETWORK using other companies tower which provides 850mhz band) signal cannot properly catch by Asus zenfone laser 2.But other brand devices such as MOTOROLA,XIAOMI,OPPO,VIVO can catch the signal of 850mhz band and the users fully enjoying the JIO4G service.Infact 1800mhz & 2300mhz signals are not properly caught by this ASUS ZENFONE LASER 2.Therefore it shows low signal.It's irritating.
