I have access to the Internet via free wifi, I have access to my fixed number via sip,
I can test google-maps and other android apps.
The Bluetooth works perfectly with the hands-free equipment of a BMW X3.
Regarding this phone, no complaints apart the battery recharge every night if you stay connected with wifi and bluetooth; if you take the trouble to disable WLAN and Bluetooth when it is not necessary, you may have hoped 3-4 days of use before recharging.
In conclusion, I do not regret my purchase!
