It was convenient to receive the SIM cards and touch-and-go service immediately upon arrival at the airport. I purchased two cards for two people, but the voucher said two cards for each person, so I was disappointed when only one was given. The staff seemed a bit casual, so I wish they would do their job more seriously. You have to replace the SIM card yourself, but the setup was easy and didn't require any special setup. I think it would be better to have a case to store your original SIM card in to avoid losing it.
