I was a bit sceptical about using this service having tried to use a similar process several years ago (different business) to unlock a phone I bought in Germany. However, having read the positive reviews on this site I decided to take a risk and was really pleased to receive the unlock into my email Inbox in just five minutes. Worked a treat. For those who might be considering this the process was just as they describe:
With the Telstra SIM in the phone dial *#06# to display the IMEI code
Locate HTC Wildfire S in the pop up lists
Carefully enter the IMEI code for the phone and select Australia - Telstra network
Supply a valid email address to receive the code to
Pay the $18.00 via my visa card ($10 cheaper than Telstra were offering and I wasn't able to do the unlock over the phone)
Wait for code to arrive meanwhile removing Telstra SIM and inserting a SIM from another provider
Turn on phone and type in provided unlock code and hey presto - I'm FREE!
Sorry for the long post but I hoped it might help others with the process. Thank you htcunlockingservice.com
Cheers
