Hi,
Not enough information to add modem support.
The most important thing is missing.. at commands to change bands and interface for communication with modem.

UNISOC vendor ID and TOZED LT70-C modem which is based from UNISOC
SL8563. The modem supports the NCM mode. Interface 0 is used for running
the AT commands. Interface 12 is the ADB interface.

P: Vendor=1782 ProdID=4055 Rev=04.04
S: Manufacturer=Unisoc Phone
S: Product=Unisoc Phone

set band-AT+SPLBAND=,<band_tdd_49_64>,
<band_tdd_33_48>,<band_fdd_17_32>,,< band_fdd_65_80>

after changing bands you have to turn on and off flight mode AT+CFUN=0 , AT+CFUN=1
