Yes, if the Nokia phone supports Java ME / J2ME, can install a JAR file, and has working internet access. On old Nokia phones, Jimm is usually the best option: it is a mobile ICQ client designed for a keypad and a small screen. On Series 40, installation is often just transferring jimm.jar to the phone and opening the file. On Symbian / Series 60, there may be additional install options, but the idea is the same. After installation, create a new account, open Jimm settings, and enter server icq.jimm.online, port 5190, TCP/OSCAR. If the Nokia does not connect, check the access point, Java permissions, SIM balance, mobile internet, and socket connection support. Some old WAP profiles are not enough; the phone needs a real internet profile. If the physical Nokia cannot get online, first test the same account in QIP on Windows, then copy the settings to the phone. This helps separate client issues from network issues.
Transfer jimm.jar to the phone, open the file, and confirm installation. On Series 40 this is usually done through the file manager; Symbian may show extra system dialogs.
A common cause is a WAP profile instead of a full internet APN. Also check the Java app permissions, the SIM balance, and whether the carrier supports TCP/socket connections.
