In the USA, This phone will NOT work with verizon. Apparently verizon will only allow whitelisted phones. I spent a couple of hours talking to various tech support agents at Verizon. The tech support agents had a difficult time accepting the IMEI number as being a real IMEI number. They were unable to get this phone to work on their network.
Vodafone is working okay for the FLX1s in the northern suburbs of Sydney Australia. One minor problem is that the signal level bar is greyed out. Very pleased with the FLX1s overall. Already my daily.
Sorry folks, I was overoptimistic. After one week Vodafone effectively kicked me off the network via an urgent warning by email to the effect that they could not guarantee me making emergency calls. Told me to stop using the FLX1s on their network by early February! Now looking for an alternative carrier.
