boropol Once my account is closed don't suppose I will be able to come on this forum either
You don't need to close your account, in fact if you're planning on coming back it might be best that you keep it open.
The pac code only transfers your number and you don't need an active sim to use the forum, however with no sim you won't earn payback but can still post.
Remember to cancel any recurring goodybags, topups, etc. that you may have too when you transfer your number out (you can do that on your account).
All the best!
