My Samsung SII purchased unlocked from Expansys locked up after a year. The original vendor would not help. Cellunlocker solved the problem at a fair price.
I then ordered a code for an older Motorola. This did not go as smoothly and I got to try out their customer service. After 4 exhanges of email over a few hours they identified my error and all was fixed.
In both cases the codes came within a couple of hours.
You cans see why I rate them Five Stars.
