Wanted to like it... – Too - A Second Phone Number Review

Great concept but not ready for the real world... First, it seems as the UK numbers are landline so no SMS. You cannot really tell what numbers are phone and which have SMS so this may be true for other numbers. Second, there is a per-minute call charge on top of the number charge. But it is very reasonable and would be worth it for a local travel number. (It gives you $1 free for calls.) But it doesn't explain this anywhere. Third, help and access to help website is tough to find or non-existent. You can give it a shot cheaply, but prepare to be frustrated.
