The Ultra Flex activation process allows individual subscribers to purchase multiple months of service through line credits. During the “Plan Length” step, select how many months you’d like to purchase. Remember, the more line credits you buy, the greater the savings. Up to 16 line credits can be purchased at once.
Current subscribers not on Auto Recharge can purchase line credits by logging into your account and selecting “Recharge.” Up to 16 line credits can be purchased.
