# Series 30+

Series 30+ (abbreviated as S30+) is a software platform and application user interface used for Nokia-branded, then HMD-branded mobile devices since 2024. The platform was introduced by Nokia in September 2013, first appearing on the Nokia 108, and has been the main Nokia feature phone operating system after the end of the Series 30 and Series 40 platforms in 2014. Despite the similar name and user interface, the S30+ is technically completely different and unrelated to the S30.
Many S30+ devices only support MAUI Runtime Environment, and application file (.vxp) developed by MediaTek, but some later devices have included support for J2ME applications. Some S30+ models also come with an online shop that allows downloading new apps and games.
In 2017, HMD Global released Nokia 3310 3G that runs the predecessor version of Series 30+ UI platform based on Mocor RTOS developed by Unisoc, called Smart Feature OS.
Since late 2023, HMD has collaborated with CloudMosa to introduce various cloud-based widgets for feature phones using the Cloud Phone ("Cloud Apps For Feature Phone") technology. This partnership marks the first time that Nokia Series 30+ devices are capable of accessing YouTube, Shorts, TikTok, Google Sign-in Services and real-time modern web applications. The first device to support Cloud Apps on Series 30+ is the Nokia 110 4G (2023), with all devices released in 2023 onwards set to feature this capability through OTA updates. However, the Cloud Phone was not supported in Europe and China.
Since 24 April 2024, HMD launched four new 4G feature phones: Nokia 215 4G (Nokia 220 4G in China, India and Vietnam), 225 4G, 235 4G and Nokia 3210 (2024), all supporting the Cloud Phone technology. The HMD 105 and 110 are the first two devices that use the brand name HMD. These phones drop the name S30+ in favor of the generic Mocor RTOS name.
