So, is it really supports both network?
Using HTC ONE DEV. EDITION in India
CDMA networks (Sprint, Verizon) don't use SIM cards, only GSM (AT&T, T-Mobile, etc.) networks do.
The Verizon and Sprint models contain both GSM and CDMA antenna hardware. If you have a CDMA device, you can get it carrier-unlocked (search the web, costs $20-30) and then activate it on another GSM carrier, or insert an active SIM from a GSM carrier.
The GSM versions of the HTC One (AT&T, T-Mobile, International, Developer, Google Play Edition, etc) only have GSM antenna hardware. They physically do not contain the CDMA antenna. So these devices would only work on other GSM networks if carrier-unlocked.
So with your HTC One Developer Edition, it only contains GSM antenna hardware, you cannot use it on CDMA networks.
There are posts floating around suggesting to flash a different radio to "enable CDMA", but I'll tell you that flashing software cannot magically make a physical piece of hardware appear in your device.
Most of the GSM radio drivers are cross-compatible (an international radio driver will still work with AT&T and vice-versa). But the Verizon and Sprint models use specific radios for those networks.
