John entered the code provided by his network carrier (which he had found online), and to his surprise, his phone displayed "Network Unlock: Successful." His Samsung A01 Core was now unlocked, and he could use it with any SIM card he wanted.

John's friends and family were also impressed when they heard about his achievement. They asked him to help them unlock their own phones, and soon, John became the go-to person for phone unlocking in his social circle.

From then on, John was known as the "phone unlocking expert" among his friends and family. He continued to help others, while also being mindful of the potential risks and consequences.

As he searched, John stumbled upon a YouTube video that claimed to show a simple method to unlock the Samsung A01 Core for free. The video explained that he needed to dial a specific code on his phone, which would generate a request for an unlock code. John was intrigued and decided to give it a try.
