3G, 4G Roaming is Not Seamless

Verizon Wireless says it can take up to two minutes for a fourth-generation network connection to switch over to a 3G radio when users move between cell zones.

"Hand-offs can take up to a couple minutes, but that was expected and a fix is in the works," Verizon spokesman Jeffrey Nelson said.

Users of Sprint Evo handsets might note a related problem, namely that when a 4G connection defaults back to 3G, it does not automatically reconnect to 4G when a 4G signal is available. It has to be manually restarted.

Those sorts of issues tend to get fixed over time.
