According to your description, the current Samsung G3819D model mobile phone does not support the use of G network card (mobile and Unicom mobile phone card) for data traffic Internet access, and can only use China Telecom mobile phone card for data traffic Internet access.

The telecom version of the Samsung 3819D model mobile phone does not support switching the Internet data card.

The telecommunications version of the customized mobile phone, although it supports dual SIM dual standby, card two can use the mobile phone card of Unicom Mobile, but it does not support G card Internet access, so it is impossible to switch the data card.

You can change your phone's SIM card from card slot 1 to card slot 2, provided that your card slot 2 also supports telecom cards. Otherwise, there is no signal.

Then you have to change your mobile phone card at the network connection to set it up.

The positions of the two cards should be reversed.
