Hey Mesostafa i can def hook you up with the unlocking. Im the owner of HorizonWirelessOnline.com - Horizon Wireless, Canada’s Cellular Repair Center ß send me an email and we can discuss price for unlocking all those units. Youll be happy with my quote. Send me a pm, and ill give you my email and we can talk from there. To see if they are locked, go to settings, advanced settings, sim card and type MEPD. its a magic menu, you wont see anything until its finished typing..
