I think it's fine as long as you have evidence of Long-Term Visa or Work Permit. I am not sure they provide an account for anyone on a Tourist Visa though.
I think when I set mine up I had to contact them by phone as my application didn't get any attention for days.
Oh another thing about TrueMoney Wallet - if the Long-term Visa or Work Permit date expires from when you set it up, they instantly lock you out of your account and you have to upload new evidence again (renewal of Work Permit etc).
