To disable the SIM card lock so you can use non-Verizon SIM cards in your Dinc2:
1. Call Verizon Global Support at 908-559-4899. Most of the reps at regular Support (*611) do not know how to disable SIM lock.
2. Once you give Global Support your phone number, they can look up the MEID/ESN of your phone from your account data and issue an MEP unlock code immediately.
3. Once you have your unlock code, on your Dinc2, go to Home|Settings|Security|Disable SIM card lock and type in your code.
4. Swap out the SIM card for a non-Verizon SIM.
5. Go to Home|Settings|Call|Preferred Network and select GSM/UMTS Mode.
Like mamuco, this is exactly what I did. Have been a VZW customer for years, though, and they've unlocked several blackberries for me, so I guess I'm a good risk for them. The agent at the Global Support desk transferred me to a Global technician to get the unlock code. Took about five minutes, and I didn't need to know my current SIM ID - just my current phone number. Without a global unlimited data rate available to us anymore, having local data access is much more important now. Used to be $69/month unlimited, but now, as the agent described to me, it's $100 for 70MB. Ouch.
I'm using a Vodafone UK SIM right now. If you are doing for the first time, be sure to know what APN's you need and how to enter them when you arrive so you can use the data networks (a google search for the local carrier and "APN" should do it). As a long-time CDMA customer, I wasn't aware of this the first time I tried to use data on a local SIM, and I had to go to a physical store for help. If you know the APN's and have your phone unlocked, you can pick up a SIM card out of a vending machine when you arrive.
Plus, I love the phone. I am familiar with the original Incredible, and I've used an original Droid, a Galaxy Tab, and Aria/Liberty personally, and I'm really pleased with the speed, camera, battery life, and even the stock UI on the Inc2. With the Incredible S getting 2.3 today, I'm hoping that we're not far behind on the Inc2.
