One of our readers asked me today if it’s possible to get a new Droid 2 or Droid Incredible and switch it back and forth from his Droid X.
Let me tell you that it IS possible even though Verizon doesn’t use SIM cards.
Verizon is based on CDMA, meaning it uses ESN numbers, which you can switch to another phone without signing up for a new 2 year contract online at VerizonWireless.com.
However, if you haven’t gotten your Droid X rebate YET, DON’T SWITCH as you will lose your rebate. Part of the rebate conditions are that your ESN number on the Droid X stays the same for the first 30 days.
After that you should be fine, you can go ahead and buy a Droid 2 without a contract, Droid Incredible without a contract, etc…etc…
This is good to know for those of you who upgrade phones a lot so have it somewhere in your brain, you never know.
Here’s how to switch between multiple phones and Droid X on Verizon: (via howardforums)
More specifically, login to My Account Online at verizonwireless.com and you can change your ESN online. Then just dial *228, option 1 and you’re good to go
P.S. Sprint is also same thing, you can switch ESN numbers just like Verizon.
