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 test Jimm through J2ME Loader on Android. 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 test the client, Android emulation is faster. If the goal is nostalgia, a real Nokia or Sony Ericsson feels very different.
You need a client, a new UIN, and correct server settings. Use QIP 2005 for Windows, Jimm JAR for a feature phone, or J2ME Loader on Android with the same JAR file.
Jimm is for real Java phones and mobile ICQ nostalgia. QIP is useful for first testing because desktop errors are easier to see and settings are faster to change.
