As per my prediction:
Mostly they will launch AirFiber along with the commercial rollout of 5G tariffs. I would expect the mobile plans which have a daily 4G data quota to get either 10 to 15 GB of 5G quota per day or 300 to 500 GB bulk 5G quota per month depending on the plan denomination.
As for the FWA segment (AirFiber, portable and non portable) there may be a separate set of pure-5G plans with data quota up to 3.3 TB a month similar to Jio Fiber. And the sims to be locked to the device or made non-usable with smartphones.
They may offer some free bundled usage or 1 month free trial on buying the device and a full refund if you choose to not continue beyond the free trial.
