Root, Custom Rom to Unlock?

Hello,
From what I have read if I understand correctly if I root the verizon droid 2 global, then install a custom rom the phone will be unlocked and I can use any provider outside the usa.
Can you confirm if this is in fact correct?
Also I live in Florida but have a german cell phone with a german chip that I use here in Florida. If the above does unlock the phone, when I put my german chip in the phone will it work in the usa or do I need to also do the band unlock first?
Thanks
JB

No. Custom ROMs don't support the SIM unlocking mechanism of the D2G, nor they disengage the SIM lock.
You have to unlock the device with an unlock code to use it with SIM cards that aren't Verizon-issued.

Thank you for the information.
I guess there is no way someone can shoot me a bone and provide the unlock for free since ive been a member for 3 years? It would be appreciated greatly...

The unlock code is specific to each handset, so no-one has one that they can give you.

Rooting and Band Unlock Help Please

Hi Guys,
I have a D2G unlocked thanks to another member who was kind enough to assist me.
The situation now is I am currently in the USA and have a German chip in the phone. I believe it is not working as it is band locked to Verizon in the USA.
From what I read have to band unlock the phone but to band unlock I have to root first. Problem is there are so many rooting methods I am getting somewhat confused.
So my D2G is Android Version 2.3.4 and System Version is 4.5.629.A956.Verizon.en.US
Could you tell me what steps I need to do to get the band unlock?
Thanks in advance.

I think I was able to root my phone successfully. I followed all instructions and used USB boot.
Is there an easy way to confirm I have indeed routed my phone?
Thanks

It should be sim unlocked out of the box. Have you stuck a sim in the phone and tried to add Telus APNs?
The only root exploit available for the VRUDNE1 4.4.2 OTA is to use Towelroot. There is no bootloader unlock available for this OTA which means there is no chance for AOSP nor downgrading the firmware to anything prior to 4.4.2. Safestrap is available but you would only be able to dual boot another VRUDNE1 based rom, nothing else.

Of course it didn't, the sim card would belong to the previous owners phone number etc. You need a sim from your carrier with your info, phone number etc. See my post http://forum.xda-developers.com/showthread.php?p=58582227

Does anybody found a way to do it? i cant buy it online....

SIM Unlock
If you have your phone paid off and/or have had service for a few months, you should be able to get the unlock code and instructions from TMo. They provided me with the aforementioned info without any pushback. Just call their support number or hop on chat and they will help you out. Also it's free
