Only the Whatsapp app needs sometimes a bit too long to the messages are there, despite a full reception. Whether this is due to the app or on the phone I can not say - the result is not that great anyway. But is relatively rare (1-2 times in 2 months) still sucks it in moments.
What's a bit annoying, that's not a data cable is possible - via Bluetooth is the PC connection, even with the Nokia Software, however, no problem. And that no data cable is possible, is indeed described.
Any other existing software works fast and flowing and make me a mature impression.
Overall, I am very happy to have got a decent touch-tone phone with no frills in a neat design. And then in this good quality and low price in my opinion.
