AT&T announced its new Build-A-Plan wireless service launching May 27, offering customers unprecedented customization options. The entry-level option costs $15 monthly with unlimited talk and text but just 1GB of data, positioning itself as cheaper than T-Mobile or Verizon equivalents. This flexible approach targets light data users seeking budget-friendly mobile service.

The plan's structure allows customers to add 5GB of data for $5 or 15GB for $10 monthly. Those needing more can choose unlimited SD video streaming for $35 or UHD for $40. Hotspot options range from 5GB to 50GB for additional fees. Crucially, the service is pre-paid with no data rollover, and streaming speeds cap at 2Mbps on 5G without an unlimited plan.

This offering directly competes with Google Fi's flexible model but requires eSIM-compatible devices. The plan serves light data users who primarily rely on Wi-Fi, those needing occasional extra data, or single-line customers ineligible for family plan discounts. AT&T's Build-A-Plan delivers a genuinely budget-conscious option for wireless consumers seeking control over their spending.
