The price of legacy AT&T unlimited plans will increase from April 2026, with single line plans increasing by $10 per month and multiple line plans rising by $20. This move is part of a strategy by the company to persuade customers to switch to its new unlimited plans. However, some customers are not seeing the changes differently, with one stating that plans with less than 6GB of data are increasing $5 per month if they include more than 600GB. As part of this change, customers will receive an additional 20GB of hotspot data per month starting in 2026.
