v1818ct型号是什么手机

VIVO Y93S is the mobile dual-SIM version of V1818CT. Launched on December 10, 2018, the mobile dual-SIM version Y93S (V1818CT) supports SIM cards from all major carriers, including Mobile, Unicom, and Telecom. When using one Mobile card and one non-Mobile card (Unicom, Telecom), the Mobile card is automatically set as the primary data card and cannot be changed through settings. However, when using two Mobile cards or two non-Mobile cards (Unicom, Telecom), the data network can be manually switched by setting either Card 1 or Card 2 as the primary data card. In the case of using two Telecom cards, the secondary card (non-data card) must have VoLTE service activated and VoLTE HD calling enabled. Additionally, the use of dual Telecom cards requires network support for 4G VoLTE service from the carrier.
