We actually don't have the code... that's the answer I got the next day.
I needed a back up cell and had found a good deal. Being locked to a different carrier I asked the guy to send me the IMEI.
Entering all the phone and carrier info on GSM Liberty, their webpage confirmed the phone model and set the price and code delivery time.
The next day what I got was not the code but a message, stating that they couldn't find the code...
Of course they never offered any explanation. You can also call their help line, in case you wanna speak to Apu...
Wasted time and stuck with a phone I cannot use.
