Over the past few days i’ve unlocked about 4 phones and hardlocked 1 😳
The one i hardlocked was an old nokia 6101 which i later found out had a firmware version which made it difficult to remotely unlock using codes.. so i had to send that one away as it can only be unlocked using cables and boxes.
Basically you get 3-5 attempts to unlock a phone. You input your network operator, phone serial number and model of phone into a calculator and you’re given 7 generated codes. Key in the codes into your phone and usually it’ll unlock your phone so that you can use any sim card from any operator in it.
You *can* call o2, vodafone or whatever to get the code, but i’m not sure if they have to give it to you. They could charge you. Anyway here’s a few DIY links which will allow you to do it for free.. 😉
Nokia’s are in general the easiest to unlock. Back in the days of 3210’s and 3310’s i used to be well up to date with unlocking, but i’ve sort of lost interest now 😎
