Hello, In my Nokia 2730 classic phone > Configuration > Personal configuration settings > Add new > My web. In this, when I disable "Use preferred access point", I get to manually adjust the access point settings. There are some confusing options here : 1. Data Bearer > GSM Data or Packet Data 2. Bearer settings > Dial up number Data call type > ISDN or analogue Data call Speed : 9600, 14400, 19200, 28800, 38400, 43200 Can anyone explain what these points mean and what effect they have on the internet on the phone. Thanks.
