Verizon Wireless Website shows the 6620L is NOT compatible with XLTE, however the specs show it is available on LTE Band 13 (700 Mhz) and LTE Band 4 (1700 Mhz). These are the same bands that the MHS291L operates on which IS XLTE compatible. Furthermore, PC Magazine says a software update in 2015 will make the 6620L compatible on Band 2, the only Jetpack capable of this - and even claims it is XLTE compatible. So why does Verizon Wireless indicates this in NOT XLTE compatible?

If it operates on the AWS Band 4 @ 1700Mhz as it states in the specs, then why is it not XLTE compatiable? What is different about XLTE other than the frequencies (Band 4 and Band 2 in future) that it operates on?
