Early Java-enabled phones often had severe memory limitations, which led to the infamous "Error: java/memory full" messages that plagued many users attempting to run complex applications like Viber. Despite these limitations, J2ME powered a vast ecosystem of mobile applications, from basic calculators to sophisticated games, and most importantly for our focus, instant messaging clients like Viber and its competitors.

J2ME was designed to work on devices with limited processing power, memory, and screen sizes, using a configuration known as the Connected Limited Device Configuration (CLDC) and a profile like the Mobile Information Device Profile (MIDP).
