Jimm works on phones that can install Java ME / J2ME applications. The best candidates are Nokia Series 40, some Nokia Symbian / Series 60 models, Sony Ericsson K and W series, and certain Siemens, Motorola, Samsung, and LG phones. The model name is not the only thing that matters; the condition of the exact device is important too. Check the battery, charger, memory card support, file transfer method, and internet settings. ICQ on a feature phone needs network access and socket/TCP support because the client connects to the server directly. If your mobile operator no longer provides convenient GPRS/EDGE settings, use a phone with Wi-Fi or install the Jimm Android app from Google Play. For a collector experience, choose a phone with a comfortable keypad and readable screen because typing messages is half the fun. If the goal is only to try the client, installing Jimm on Android from Google Play is faster. If the goal is nostalgia, a real Nokia or Sony Ericsson feels very different.
Java phones with a comfortable keyboard work best: Nokia Series 40/S60, Sony Ericsson K/W, some Siemens, Motorola, Samsung, and LG models. What matters most is JAR support, internet access, and a healthy battery.
Even a suitable phone is useless if it will not hold a charge, cannot receive files, or has no working internet profile. Check exactly these things before buying.
