How to Unlock a Cingular HW6515

The HP iPAQ HW6515 Mobile Messenger is a Windows Mobile smartphone available with service from Cingular Wireless before that carrier became AT&T. HW6515 phones branded with the Cingular logo may be locked to AT&T and unable to use SIM cards from other carriers. Each HW6515 locked to AT&T/Cingular has an unlock code that, when you enter it on the phone, will de-activate the lock, allowing you to use your HW6515 with another carrier's service.

Things You'll Need

• Non-AT&T SIM card

Instructions

1. Press the battery cover latch on the back of your HW6515 and slide the battery cover off the phone.

2. Lift the battery out of your HW6515.

3. Replace the Cingular or AT&T SIM card in your HW6515 with a SIM card from another provider.

4. Request the unlock code for your HW6515 from AT&T customer service. You may need to provide your phone's IMEI number, which can be found on a label underneath the battery.

5. Return the battery and battery cover to the phone and hold down the "Power" key to turn the phone on. The phone will prompt you to enter your unlock code.

6. Enter your unlock code using the phone's keypad. Your HW6515 will be unlocked, allowing you to use the phone with a SIM card from any wireless provider.

Tips & Warnings

• Even though an unlocked HW6515 will accept a SIM card from any provider, you will be unable to access voice and data services on frequency bands that the phone does not support.
