iMAN Victor Mobile

[abasu.kolkata]

I have purchased one Mobile Brand iMAN Model: Victor from Netherlands it's made in China and this phone supports: Network: 2G: GSM 850/900/1800/1900MHz 3G: WCDMA 900/2100MHz 4G: FDD-LTE 800/1800/2100/2600MHz Now I am trying to use this phone in India, Kolkata, but no SIM (tried with Vodafone, Airtel, Reliance 2G/3G/4G SIM & Jio 4G VoLTE SIM) is working, manually when I am searching network all available 2/3/4 G network are showing but not allowing to register on the network, same SIM working fine in other handsets. In Automatic Network search mode it's not selecting any network, on manual search & select it's not registering on the network & giving message "Can't connect to the network at the moment. Try again latter" Can any body please help me on this.
