This is an interesting and appreciated thing for VZW to do. Apparently, they are planning to make the new Motorola Droid 4 and the LG Spectrum global roaming capable. Being a GSM capable global roamer is a nice and unexpected feature for the Droid 4. According to the report, Verizon is working on network enhancements that will allow them to add the GSM roaming capabilities to the two phones, but those features won't be available until later on in the first half of this year.
Now, if the different carriers could all settle on a single LTE standard, then we could have global high-speed internet everywhere!
If you are going to dream... dream big!
