Commercial Mobile Radio Service / Cellular (CMRS) and VoIP Providers
The PSC does not regulate the rates, terms or conditions of commercial mobile radio service (CMRS) and Voice over Internet Protocol (VoIP) providers' offerings, nor does it regulate other facets of their operations. CMRS and VoIP providers are required to register with the PSC, however, and to file brief annual questionnaires on intrastate revenues which is used to calculate assessments. These providers, like all Wisconsin telecommunications providers, are subject to assessment for the Wisconsin Universal Service Fund and for Commission expenses pursuant to Wis. Stat. § 196.85.
CMRS and VoIP providers are required to register with the PSC. To register, the providers must provide the following information in a letter, or by providing the following information in a Word document:
- The legal name of the company, along with the physical address.
- The name, title, email address and telephone number of the official contact person for the company.
- The name, email address and telephone number of the person to whom inquiries about the application should be addressed, if different from the above.
- The name, email address, and telephone number of the person responsible for submitting the Annual Report.
- The name, email address, and telephone number of the person responsible for handling inquiries and complaints from Commission staff.
- The company website or websites
- A list of any trade or "doing business as" names the CMRS and VoIP provider will use in Wisconsin.
- A description of the types of service to be offered and the classes of customers to be served. If the company is using particular d/b/a names or websites for individual customer classes, include an explanation of which names, contact information and websites apply to each group.
- The geographic market and originating exchanges to be served. A list of wire centers in Wisconsin is here. "Statewide" or "in the footprint covered by the [name of underlying wireless carrier]" are also acceptable answers.
- An explanation of how the provider will ensure that 911 calls are routed appropriately, and how location information will be provided.
A copy of the provider's articles of incorporation (or equivalent) and certificate from the Wisconsin Department of Financial Institutions (DFI) authorizing the petitioner to transact business in Wisconsin as a corporation should be attached to the letter or application form. If the company is not registered with that office, call (608) 261-7577 for information, or write to the Wisconsin Department of Financial Institutions, Attention Division of Corporate and Consumer Services, PO Box 7846, Madison WI, 53707 7846. You may also contact that agency via their website at
The letter (or application form) and the supporting documents must be filed via the Public Service Commission's Electronic Records Filing (ERF) System. Applications for certification should be uploaded as "new / nondocket" filings under the providers' PSC utility ID number, if one has been assigned, or under the number "9300" if the provider does not yet have a PSC ID number. There is no filing fee, and petitions are generally processed within one week.
