Needed to unlock my galaxy note20 ultra I was pretty hesitant at first to use this service because of obvious reasons. Took the chance and used paypal to have the dispute option. They delivered my network unlock code in less then 24 hours, with great instructions and it worked like a charm. They are the real deal. I hardly every write reviews but the boys at cellunlock 100% deserve this.

Network Unlock successfull for Samsung Z Flip 3 J'ai commandé un code de déverrouillage réseau pour Galaxy Z Flip 3 bloqué par AT&T. J'ai reçu le code en 1 jour ouvré. Le code fonctionne a correctement fonctionné. Il suffisait de renseigner le MCK et ensuite le NCK.

I strongly advise against using this… I strongly advise against using this service. Their website claims that once a device is unlocked, it stays unlocked permanently. However, my experience tells a different story. I had 8 iPhones, all on a reseller flex plan, which were temporarily unlocked by CellUnlock. Unfortunately, about a month later, each iPhone relocked, this time to a minor carrier. Despite numerous emails and attempts at resolution, the issue remains unsolved. Now, all these iPhones are essentially useless, locked to a carrier with no available unlocking options. While they did refund the service fees, there was no further compensation for the significant inconvenience caused. Please be wary - even if your device is initially unlocked, there's a high chance it might relock.

AT&T IS THE WORST! Awesome company. AT&T was trying to hold my phone hostage even though it was completely paid off. After days of trying to resolve why with reps and management, finally receiving an email saying that my phone would be locked permanently into the AT&T network if I continued trying to unlock, I came to cellunlocker and got my code (that worked!) less than 24 hours later.
