Separately, GSMArena claims that the smartphone will be available as Galaxy S4 Value Edition in some markets. It also lists some of the EU markets where the Galaxy S4 mini plus aka Galaxy S4 Value Edition will be available including Austria, Germany, Czech Republic, Romania, and Bulgaria.
It's worth noting that the Samsung Galaxy S4 Value Edition was originally launched last year, and the new Galaxy S4 Value Edition expected to hit the above mentioned markets will be an upgraded version.
The dual-SIM Galaxy Grand Prime 4G is nearly identical to the 3G variant of the smartphone, which was launched back in September last year, except it includes 4G LTE connectivity. The phone supports both Band 3 and Band 40, which means it's compatible with 4G networks being deployed in India right now. It also runs Android 5.1 Lollipop out-of-the-box, instead of Android 4.4 KitKat.
