Supplementary Line is a plan offered by U Mobile to all existing and new postpaid customers. This plan is open to all Malaysians and Foreigners; customer must be of age 18 and above.
The credit limit is shared with the principal line. Eg. Principal Account subscribed to U88 with RM300 credit limit and its supplementary lines will share this RM300 credit limit with the principal line.
The Principal will have to walk in to U Mobile centres to get the USIM replacement. However, if you have an authorization letter from the principal, you can get the replacement card on your own.
