The last K51 device on our list is from Verizon.

Many years ago, I had the Motorola Droid 2 Global from Verizon and it was factory unlocked out of the box. This continued for many years. Now, it seems they have changed their policy to curb theft and fraudulent activity.

As per the latest Verizon device unlock policy, the device remains locked for a 60 day period after activation on the Verizon network.
