Missed calls had a larger increase in 15-minute SMS activity than calls with positive duration in four weeks of Copenhagen student records

We tested whether SMS activity changed differently around missed calls and calls with positive duration. We used the original four-week Copenhagen Networks Study call and SMS records. SMS activity means at least one message between the same two people in a 15-minute window. The rate rose from 12.30% before to 21.04% after 366 missed calls. It fell from 18.58% to 13.46% around 2,653 calls with positive duration. A comparison within 145 ordered caller and recipient pairs gave a difference in changes of 13.37 percentage points. Descriptive 95% ranges were 6.26 to 20.64 points when sampling pairs and 1.35 to 25.26 points when weighting by sampled people. The contrast stayed positive under all planned timing, duration, and sample checks. A separate scalar scan reproduced every primary SMS indicator. The package preserves source data, code, figures, and repeat instructions. This is one student network. Call purpose, ring time, message content, and automatic message status are unknown. The result does not establish cause or a deliberate switch of channel.

    We build on its call-status distinction and comparison within ordered caller and recipient pairs. We test SMS before and after calls instead of next-call direction. We wrote new analysis code.
