Hi,
my brand new xz2c doesnt book into any of the available local mobile networks. It only detects the network as 2G but I know I have full 4G coverage here (!&&* the cell tower is right across the street!). Problem is I only found this out after I had already unlocked the bootloader so now the support company refused a repair/exchange. But they DID officially confirm the issue at least, happening on latest stock image/firmware (and LineageOS too). Anything I can do here or is that thing now a wifi-only “phone”?
