Pepwave MAX HD1

We are Fastlink Co. partner of peplink in Yemen.
We have MAX HD1 Devices. Are there firmware or another way to make that device supports CDMA 3G?
I found that MAX HD2 Support 2x Embedded 3G Modem ( CDMA: Verizon and Sprint Certified)
But MAX HD1 Support GSM Only.So, we need some way or firmware or any attachment device make HD1 support 3G of CDMA 2000 EVDO
