Your package will stay in Belgium for a week if you order with standard shipping to Ireland.
I had to wait one month for my phone, but it says it would take 10 to 20 days. If you are buying something from china with standard shipping it will take one month, this is mainly because it stays in Belgium for a whole week, I thought it was lost there but other Irish people ordering from China had the same problem as me. Also when the package did arrive the sellotape securing the phone box was cut, I am not sure if it is normally like that, but the phone looked like it was safe in the cover.
