T-Mobile for Business pricing on the CoreMobile and SuperMobile plans is structured per line with significant savings on multi-line accounts. All pricing below requires Autopay and is plus taxes and fees.

Buyers evaluating T-Mobile’s pricing should request written confirmation of which specific plan terms are protected by the 5-Year Price Guarantee and which T-Mobile reserves the right to modify, given the 2025 class-action litigation challenging the scope of that guarantee.

Final Verdict: T-Mobile for Business Review

T-Mobile for Business earns an Expert Score of 4.6/5.0, reflecting its operational strength as a wireless-first communications provider. Our analysis confirms its leadership in 5G network coverage and performance (Best Mobile Network in the U.S. per Ookla 2H 2025), which is a significant advantage for SMBs with 11 to 999 employees seeking alternatives to traditional wired internet. The current Q2 2026 lineup offers CoreMobile (essentials) and SuperMobile (premium with Network Slice and Threat Protect), supported by a 5-Year Price Guarantee on monthly on-network talk, text, and 5G data.

Business customers should weigh the operational strengths against the regulatory and reputational record: T-Mobile USA, Inc. is not BBB Accredited; the BBB profile shows 26,942 complaints in 3 years and a 1.13/5 customer review average; there is an active BBB Government Action alert citing Multi-State Attorneys General; and the company has been subject to multiple settlements totaling over $440 million in recent years (data breaches, advertising practices, throttling) plus ongoing 5-Year Price Guarantee and hidden fees class actions. Performance for SuperMobile Network Slice features requires Ultra Capacity 5G coverage with capable device.

For Q2 2026, the active offers (10 lines for $200 + $150/line credit on CoreMobile, 20 lines for $20,000 savings on SuperMobile, $1,500 activation credit for Small Business Month on 15+ SuperMobile lines) provide meaningful incentives for SMBs in T-Mobile’s target verticals (Retail, Hospitality, Construction, Manufacturing, Healthcare). Our recommendation: T-Mobile for Business is a strong option for mobility-first SMBs, provided buyers obtain written confirmation of all plan terms (especially 5-Year Price Guarantee scope) and review the BBB Government Action alert and settlement history during their evaluation.
