the SIM is already activated and receives excellent LTE speeds on all my other phones, tested. The wifi issue is caused by the X3, even with all other devices disconnected it kills the wifi both on 2.4 and 5, cant really explain it, this is a brand new cable modem router picked up last night cause at first I thought it was a problem with the router and not the phone. No other devices that I use on the network cause issues, only when the X3 connects to it. No the other devices can not reconnect after the network goes does, I have to reboot the cable modem/router. When the router goes down wired connection still works but wireless does not work and is not visable to any of my other devices. If I turn off wifi on the X3 and reboot the router everything works smooth as butter getting 170 down 40 up. The LTE speeds being bad are just on the X3 same sim in other Lumia devices, android and iPhone get great speeds, so that too is strictly the X3 issue. I'm taking the phone back tmo and getting refund cause I cant pay over $1000 for a 3G phone that cant connect to my wifi.
