How to access wifi with WEP encryption

Hello,

I just bought Samsung S3653w for the reason that i can use it at my home with wifi connections..but the problem is i cannot access my own wireless spot. The following are the wifi details as seen on my mobile phone when i am trying to connect. I know my wireless WEP key with 13 characters but i dont know where to enter it in...Please help me to have my mobile connected to internet. Thanks in advance.

Auth Type - open
Encryption type - WEP
Key length - 64 bits
Index ID -1
Network key - limit to 10 characters only
