Nokia is pushing out the new Lumia 520 and Lumia 720 Windows Phones, but what's interesting to note (if you're looking to utilise such functionality) is how the two new Nokia smartphones do not come packing HERE Drive+, but the Lumia 620 does. Windows Phone forum member powersquad received a response from Nokia that may help clear some of the confusion.

We've first got to start with the difference between HERE Drive and HERE Drive+. The former provides turn-by-turn navigation in a single country or region, while the more advanced solution covers almost 100 countries. The selected country or region is calculated with the app launching for the first time, taking into account the country the inserted SIM card belongs to.

All this means is that if you purchase a Lumia Windows Phone with HERE Drive, you'll be limited to the region (or country) the SIM card inserted belongs to. Should you buy one in the UK and insert a US SIM card, you'll have the service activated for use in the states. This is the same for all other Windows Phones that now have access to Nokia's navigation app.

It's not a major difference, but if you're looking to travel abroad, what are your options to use the HERE Drive service and Windows Phone when in a different country not currently supported? For the time being, there's nothing available, not until the HERE Drive apps reach commercial status and are out of beta. But should you be packing the HERE Drive+ app, you're all set to go.

For those with the HERE Drive app, it'll be possible to upgrade to the plus version with a global navigation license for around 100 countries. Nokia hasn't released any information regarding when the apps will come out of beta, or just how much the upgrade will cost consumers. Note that this does not affect HERE Maps. Consumers can download all country maps to the device and enjoy walk navigation, etc.

"So far we haven’t announced any details about timing and pricing yet, but we’re planning this step for the coming months. And even though you will have to pay for the upgrade from Drive to Drive+, you will save more money on roaming costs and data charges when travelling abroad thanks to our leading true offline capabilities than you will have to invest for the worldwide navigation license. This is unmatched by any 'free' mobile navigation solution on the market today."
