# How to Prepare the Wireless Module

If your business uses wireless sales or bill payment, confirm the module’s core records before launch.

- Add the carriers your store sells.
- Add the providers used for service or bill payment.
- Review carrier and provider availability.
- Attach the correct surcharge behavior where applicable.
- Test a safe wireless workflow.
