Beware to Duplicates! 

There are some duplicate in the market now, which plagiarized our design. It’s techniques are very crude and incomplete.

 Fake ones normally have black line route on board and also small different than the real one. Please compare with your "GEVEY-3G" sim and make sure you have a real one before asking any questions of trouble shooting.

 There are more than two type of fake GEVEY-3G sims on the market, if you have one different than the one showing on above. Please send us a picture with front and rear side. Many thanks!
