The shopfront is optional. The billed services are not.

Mobile dealers often mix walk-in retail with a quiet business-account book. Buyers in this network usually care about the connections, dealer codes and residual trail, not the lease on the high street.

If you are a dealer, a partner, or a small telco reseller with handsets on the side, describe the mix honestly. A private sale can split retail from the B2B book if that is what makes the file transferable.
