You have to use it at least once in 30 days (i.ex: make or receive at least 1 call).

They will renew it every months as long as you use it, so you can keep your free number for ever. If you don't use it after 30 days it gets canceled (but then you can request a new number).

The free INUM number (+88351000: the new worldwide local call - can be called via SIP or worldwide local dial-in numbers: Dial in numbers | inum ) however, has no limits. You keep it even if you don't use it.

The INUM number is very useful for:

• calling people who have INUM numbers (SIP users)
• forwarding between SIP providers that don't allow SIP address calling/forwarding but do handle free INUM calls (i. ex: betamax clones, localphone,... don't allow external SIP addresses, but call INUM for free)

Edit: these landline & mobile operators route calls to INUM: http://www.inum.net/?page_id=22 , and these are known to route SMS to INUM : http://www.inum.net/?page_id=24
