"Cellunlocker asked me to give my honest feedback on my order with them, and did not offer me any compensation for this review. I have never heard of resellerratings before either, this is my first time here.
I was given a locked phone from my friend, and since I am on a different network I was looking to unlock my Galaxy S3. I found cellunlocker and paid them to unlock my phone, which cost a fraction of what the original provider (Bell Canada) was asking.
Cellunlocker gave me an unlock code in reasonable time (during business hours) but I had problems with the unlock code. I sent them an email detailing my problems and they got back to me with some options to try in a step by step fashion.
I did their troubleshooting steps and it worked, the Galaxy S3 is now unlocked and I am very happy with their service. I was worried that the unlock wouldn't work or that the seller couldn't help me with my issues but they came through in stellar fashion. I would buy from them again to unlock another phone anytime."
