dont get confuse.. it mean your credit wont expired till you're 26 years old..
1. its not 3g activated by default, you need to upgrade to 3g simcard first.. however, if you're porting from maxis/digi/umobile to UOX, you may request 3g simcard straight away..

2. no credit expired mean, you can use your available credit at anytime without worries about it will expired.. you can reload rm10 today, and keep it till next year for example but still can use.. it wont expired.. only expired after you're 26 years old.

* again, for those people who their credit still got normal validity.. you need to visit celcom branches, and verify your mykad, personal info, etc.. then only celcom will give you this special credit validity..
