I was gifted a Samsung Galaxy S21 Ultra 5G by my cousin in the US. Iam in India.
He had been using his phone a short while in the US with carrier AT&T.
I paid freeunlocks USD 39.99 to unlock my phone.
Payment made: May 12, 2022
Code promised : May 15, 2022
I emailed them on May 14 as a reminder. I got a reply on the same day stating that they had a delay, and that if I wanted they would refund me.
I said I would wait.
They sent the code on May 19, 2022.
It worked the first time and my phone was unlocked. Now Iam using it with an Indian SIM!
So thank you!
I was initially afraid this was an internet scam and that i had lost my money,
But at least in my case, they sent the code and my phone is unlocked.
Thanks again to the company!!

I think it worked really really good got me all the answers I needed to know about my phone..very satisfied thank u unlockbase.
Neat! Phone was unlocked much faster than expected. on 05/21/2022
ATT gave me a hard time when I tried to get my iPhone 13 mini unlocked through them. So I ended up putting in and paying for an unlock through Unlock base. I put in the request Thursday and an email arrived around Friday midnight saying they were able to get the phone unlocked and low and behold, the about section on the phone now says "No SIM Restrictions". This was a very pleasant surprise and much faster than expected. I can definitely vouch for this company!

This website is the only one that was able to unlock my galaxy s20 Ultra and in a timely matter. I tried two other websites with no luck. I will be unlocking two more devices!
