How To Unlock Palm Treo Pro
Learning how to unlock a Palm Treo Pro takes a few steps. Unlocking a Palm Treo Pro requires a Palm unlock code and can be done in a few steps. Unlocked Palm Treo Pro’s will work on any GSM phone network you choose! Essentially all GSM or SIM based Palm phones in general come with a SIM lock by default. This SIM lock prevents them from working with other phone carrier’s SIM cards. The free unlock instructions in this phone guide help disable this SIM lock.
Before you can use the free unlock instructions on your Palm Treo Pro you will need a palm unlock code. You can usually get a free unlock code for your phone by calling up your current phone carrier and requesting one. I have heard a lot of success with both AT&T and T-Mobile. In exchange they will request your Palm Treo Pro’s IMEI number, which you can find easily by typing *#06# and hitting enter on your keypad.
Once you have your Palm Treo Pro’s unlock code, use the instructions below to remove the SIM lock. Warning: Entering 3 or more incorrect unlock codes could permanently lock your mobile phone!
