This study evaluates the performance of classical and quantum-inspired sequential models for univariate time series prediction of received SMS activity using the Milan Telecommunications Activity dataset. Due to data limitations, we focus only on SMS reception signals for each spatial grid cell. Five models are compared under various input sequence lengths (4, 8, 12, 16, 32, and 64). All models are trained to predict SMS reception values for the next 10 minutes based solely on past values within a given sequence window. The results indicate that different models exhibit varying sensitivity to sequence length, suggesting that quantum enhancement is not universally beneficial. Rather, the effectiveness of quantum modules is highly dependent on the specific task and architecture design, reflecting inherent trade-offs between model size, parameterization strategy, and temporal modeling capabilities.
