As the group owner or primary account holder with TGTVS Mobile, your billing date is determined on the day you activate your number. If you’re a secondary line holder on the plan, your billing date aligns with the primary account holder’s. Should a line be activated on the 29th, 30th or 31st of a month, the billing date will reset to the 28th for all subsequent billing cycles. This ensures a consistent and smooth billing process for everyone on your plan.
