Walmart Family Mobile is one of 6 brands on a single FCC registration
Walmart Family Mobile is operated by Verizon Value, Inc. of Florida, which has filed with the FCC under the same registration since 1997 — 29 years. Only 42 of the 360 carriers and MVNOs currently filing in this category hold a registration that old. The same registration also covers Tracfone, SafeLink Wireless, Simple Mobile, Page Plus Cellular and Total Wireless. The customer-inquiries line on file with the FCC is 1-800-867-7183. It is a separate contact from the support number above, and worth trying if that line goes nowhere. Checked September 22, 2026 against the FCC Form 499 filer database.
