Major carriers like AT&T, T-Mobile, and Verizon charge $50-$100 monthly for postpaid plans, often bundling unwanted extras. Mobile virtual network operators (MVNOs) lease network access from these carriers and resell it at lower rates. MVNOs like Mint Mobile, Visible, US Mobile, and Google Fi Wireless operate on the same infrastructure but prioritize direct carrier customers during congestion.

Most MVNOs use prepaid models without contracts or credit checks, avoid physical stores, and skip bundled subscriptions to reduce costs. Mint Mobile (owned by T-Mobile) offers plans starting at $15/month for 6GB on a 12-month term. Visible (Verizon's MVNO) provides unlimited data for $275/year including taxes.

US Mobile supports all three major networks with flexible switching and shared family data pools. Google Fi Wireless excels for international travelers with data working in most countries on its $65/month Unlimited Premium plan. Switching to an MVNO can significantly lower phone bills while maintaining reliable coverage on major networks.
