I requested a code for an LG G3 mobile phone, as my network were going to charge me a crazy amount to buy out the contract and unlock the phone. The website itself looks very dated and basic, but I decided to give it a go as it was a lower price.
The code came in a very reasonable time frame, but entering it into the phone was another matter!
I expected one code, but was presented with five. I'm not very technically savy and the instructions were not clearly written in laymons terms. There was a great deal of information in there that I simply did not understand. This delayed me using the code as I had to get help from customer support, who do take a while to answer emails.
Once I had clarified which code to use, and how to enter it the phone did however unlock and accept mu new sim card.
I recommend updating your instructions, you need to remember that we are not all technically minded and do need a little extra help when it comes to things we aren't familiar with.
Other than that, thanks for the code and I would come back
