AT&T is once again raising the prices of its grandfathered unlimited data plan, up from $40 to $45 for anyone who’s managed to still hold onto one since AT&T discontinued the original $30 unlimited plan in 2010, via MacRumors.

This marks the third time that AT&T has raised the price for grandfathered unlimited customers in the last decade (first to $35 back in 2015, and then to $40 last year). While the slowly increasing price tag is certainly onerous to customers, you’re still paying far less than any of AT&T’s current unlimited plans, which the company reintroduced in the wave of new unlimited plans last year.
