Fixed wireless would offer more consistency than 5G residential service, as the 5G service is lowest priority on the tower and a way to squeeze more revenue out of the network and spectrum.

Due to how few units there are, your options are fairly limited unfortunately. You might try bonding together ATT, Verizon, and T-Mobile 5G Home service with a compatible router if there are no other options. It’ll cost ~$120-$140/month, but you’d have diversity that might improve the overall experience. When done natively vs using their 5G home devices, this is referred to as “cellular carrier aggregation.”
