Build Your Own Plan | Customize Wireless from AT&T​

This guide is a comprehensive reference for AT&T Build-A-Plan, designed to walk through every detail of how the plan works — from the base $15/mo. service through the available wireless data tiers, hotspot options, configuration rules, and signup process.

It includes detailed tables covering all 13 valid plan configurations, the complete pricing matrix, eligibility requirements, and how Build-A-Plan compares to AT&T's postpaid wireless plans. You'll also find answers to the most common questions about hotspot add-ons, mid-cycle data options, plan changes, billing, device requirements, and what happens if you run out of data. 

Available wireless data tiers include 5GB, 15GB, unlimited SD, and unlimited HD, with optional hotspot tiers of 5GB, 25GB, and 50GB based on the wireless data tier selected. The unlimited HD tier includes 4K UHD streaming; other tiers stream video in standard definition. Plan changes take effect at the next monthly renewal, and mid-cycle 5GB data add-ons are available for $8 (good for 5 days).
