Not long after HTC and Sprint cut a swath through CTIA with the debut of the highly anticipated HTC Evo 4G, HTC representatives have confirmed that the device will not support simultaneous 3G voice and 4G data access.
“If you’re using 4G for data, you can’t use CDMA for voice. Currently the only way to do simultaneous voice and data would be through a third-party VOIP solution. However, this is not do (sic) to strict hardware limitations, so it’s possible this could change with future updates.”
Since the limitation is not strictly due to hardware, the only other logical explanations revolve around Sprint and the apparent arbitrary limitation placed on device functionality as well as Android’s limitations.
Update: Sprint has posted a new tweet in regards to simultaneous 3G voice/4G data access, confirming the following:
“Voice+Wi-fi=Yes, Voice+3G=No, Voice+4G=Still TBD, still being tested”
The above now puts to rest initial speculation regarding any limitations placed by Sprint and clarifies what the hardware can and can’t do (yet.)
