AT&T is increasing rates on its "retired" unlimited wireless plans by up to $20 per line starting in April, according to a support page on its revamped "2.0" service tiers. The price increase is capped at $20 depending on the number of lines. Affected plans will receive an extra 20GB of high-speed hotspot data each month. The changes only apply to wireless plans activated prior to July 24, 2025. If you signed up for the company's previous AT&T Value Plus Plus VL, Unlimited Starter SL, Unlimited Extra EL or Unlimited Premium PL plan in the last half of 2025, this increase won't apply to you. The increases make it worth comparing prices between holding onto an existing plan or switching to the new plans.
