I have a Samsung S7 and a Canadian mobile service provider. I recently switched providers but, due to the age of my phone, it was locked to the previous network and needed to be unlocked by them. After spending several days trying, in vain, to contact a real person to get the unlock code (in Canada, this must be done, at no charge, when a customer requests it), I searched the web for an online unlocking service. Cellunlocker.net came up again, and again, as a reliable and trustworthy provider. So I submitted the necessary info about my Samsung S7 and, within 24 hours, I had a return email with the unlock code. It worked on the first try. My phone works perfectly on the new network. Cellunlocker is a great service and I would certainly use it again, if needed, and would recommend it highly to anyone who needs their phone unlocked.
Pros and Cons:
Bottom Line: Yes, I would recommend this to a friend
