How do I get a dual sim model in Grey? Also how do you mark it for customs? every time DHL deliver there is importation tax to Thailand. I think it is the invoice price. How do you show invoice price. I want avoid heavy import tax. Reply:you can leave comments of color and sim type on step 2 of 3 before check out,always we write the phone as gifts value 50USD only on invoice,so you will not pay taxes,thanks...
