Which phones are the most comfortable
For daily use, pick models with a comfortable keyboard and a readable screen. Nokia is easiest to set up, Sony Ericsson feels good in Java, and Siemens brings strong nostalgia but needs some patience.
What to check before buying
Ask for a photo of the phone powered on, and check charging, battery health, file transfer, JAR support, and access to network settings. Without these, Jimm may not work even on the right model.
