I ordered unlock codes for two different phone models. I received both within a hour.
I was worried one of them would not work because the model number was one digit higher than the model CellUnlocker listed on it's site.
However, both codes worked without issue.
CellUnlocker's email provided clear instructions and guaranteed they will support purchases.
However, I feel CellUnlocker's website could be improved to be more clear in guiding the customer. Some navigation and instructions on the right & left side are extraneous, and may be making purchasing more confusing than helpful.
