To keep this free line credit
  • To validate eligibility, a customer’s total number of active voice lines was captured on the promo's announce date of April 7, 2026. We add the number of newly-activated voice lines required for this promo, which includes the free line, to this number. That final, combined number of active voice lines must be maintained for at least 1 year after enrollment to continue receiving credits. 

    Example:     An account with 2 active voice lines on  April 7, 2026, must activate 2 new voice lines to enroll, and they do so on April 9, 2026. They must then maintain all voice lines for 1 full year after promo enrollment April 9, 2027).
  • After 1 year of enrollment, customers must keep at least 2 paid voice lines AND the free new line that was activated to enroll in this promo to continue to receive the credit.
  • No Install cancellations for voice lines will not impact the free line credits.

     Your credits should begin within your first bill cycle after activation, but in some cases, it may take up to 2 bill cycles to begin. If you don't see a credit on your first bill, don't worry. You'll see a double credit on your second bill.

FAQs

Customers shouldn't cancel an existing voice line with the intention of replacing it with a newly activated voice line to take advantage of this promo, even if the cancellation happens after the new voice line activation.

Customers should never be told to cancel lines, before or after a promotion, in an effort to qualify or justify a promotion. If a customer does not need additional lines, explore other promotions or discuss device price points. Driving CHURN to close sales is not the right thing to do.

The free line credit applies to newly activated lines with logic this way:

  • AAL lines with subscriber-level MRC receive the credit first before lines that are included in a family/pooled plan MRC 
  • Lines with lowest MRC receive the credit
  • If multiple lines have same lowest MRC, lines with earliest activation date/time receive the credit

It depends on the type of line and timing:

  • Paid lines can qualify for device promotions (including monthly bill credits) at activation and on future upgrades, if promotion requirements are met.
  • BOGO or targeted promo lines are not eligible for device promotions on upgrades.
  • Other discounted lines (e.g., 3rd Line Free, Yearly Upgrade) may be eligible, depending on the specific promotion requirements.
