Advertisement The addition of truly uncapped data for AT&T’s Unlimited Elite plan is set to arrive this week as a no-cost upgrade for both new and existing subscribers, with the plan’s cost staying the same at $85 per month for a single line, or as low as $45 per month for a plan with five Unlimited Elite lines. The uncapped data will apply to both 4G LTE and 5G data, with AT&T saying it will send a text to any existing customers when the free upgrade gets applied to their plan.
