“…For instance, nowadays, quantitative reports of sending instant messages or using social media network sites may be mixed up by participants with reports of sending SMS text messages ( Berolo et al, 2015 ). Moreover, recent research indicates that heavier voice and SMS users are more likely to replace mobile network voice calls and SMS messages with calls and messages over mobile internet (data) usage, possibly due to higher cost savings and unlimited ‘data packages’ on offer from mobile network operators ( Gerpott and Meinert, 2016 ). Hence, it would be more difficult to tease out accurate call frequency/duration and messaging agreement between self-reported and mobile operator traffic data for such individuals.…”

Mobile phone use, predominantly smartphones, is almost ubiquitous amongst both adults and children. However adults and children have different usage patterns. A major challenge with research on mobile phone use is the reliability of self-reported phone activity for accurate exposure assessment. We investigated the agreement between self-reported mobile phone use data and objective mobile operator traffic data in a subset of adolescents aged 11–12 years participating in the Study of Cognition, Adolescents and Mobile Phones (SCAMP) cohort. We examined self-reported mobile phone use, including call frequency, cumulative call time duration and text messages sent among adolescents from SCAMP and matched these data with records provided by mobile network operators (n = 350). The extent of agreement between self-reported mobile phone use and mobile operator traffic data use was evaluated using Cohen's weighted Kappa (ĸ) statistics. Sensitivity and specificity of self-reported low (< 1 call/day, ≤ 5 min of call/day or ≤ 5 text messages sent/day) and high (≥ 11 calls/day, > 30 min of call/day or ≥ 11 text messages sent /day) use were estimated.Agreement between self-reported mobile phone use and mobile operator traffic data was highest for the duration spent talking on mobile phones per day on weekdays (38.9%) and weekends (29.4%) compared to frequency of calls and number of text messages sent. Adolescents overestimated their mobile phone use during weekends compared to weekdays. Analysis of agreement showed little difference overall between the sexes and socio-economic groups. Weighted kappa between self-reported and mobile operator traffic data for call frequency during weekdays was κ = 0.12, 95% CI 0.06–0.18. Of the three modes of mobile phone use measured in the questionnaire, call frequency was the most sensitive for low mobile phone users on weekdays and weekends (77.1, 95% CI: 69.3—83.7 and 72.0, 95% CI: 65.0–78.4, respectively). Specificity was moderate to high for high users with the highest for call frequency during weekdays (98.4, 95% CI: 96.4–99.5).Despite differential agreement between adolescents’ self-reported mobile phone use and mobile operator traffic data, our findings demonstrate that self-reported usage adequately distinguishes between high and low use. The greater use of mobile smartphones over Wi-Fi networks by adolescents, as opposed to mobile phone networks, means operator data are not the gold standard for exposure assessment in this age group. This has important implications for epidemiologic research on the health effects of mobile phone use in adolescents.

“…Accordingly, mobile and telecommunication organizations have been looking forward to expand their products and services provided by mobile phones (i.e. mobile internet, mobile payment, mobile social media, mobile government, mobile commerce, mobile shopping, and mobile learning) (Alalwan et al, 2016;Gerpott and Meinert, 2016;Laukkanen, 2016;Rana et al, 2016;Shareef et al, 2018;Xu et al, 2017). The evolution in mobile technology also represents more opportunities to be utilized by business and governmental organizations to introduce their products and services in a more effective and efficient manner (Mascheroni and Ólafsson, 2016;Tran and Corner, 2016).…”

Mobile internet represents a breakthrough technology that has derived much attention from mobile organizations and services providers in the Kingdom of Saudi Arabia (KSA) 1. However, the level of acceptance of mobile internet in the KSA is still below the level of ambition. This is in addition to the fact that there is a considerable need to discover the main factors shaping Saudi customers' intention and adoption of such a mobile system. For this reason, this study is conducted in the hope of providing further understanding about the adoption of mobile internet in the KSA. The extension version of Technology Acceptance Model TAM 2 with perceived enjoyment was adopted as a theoretical foundation of the current study model. This was expanded by considering two additional factors: innovativeness and trust. The main empirical data collected through questionnaires was analysed using structural equation modelling (SEM) 3. Perceived usefulness, perceived enjoyment, trust, and innovativeness are statistically supported to have a significant impact on the Saudi customer intention to adopt mobile internet. Further discussion regarding the main contribution as well as research limitations and future directions are presented at the end of this paper.

“…One of the great challenges operators face is how to compete with other OTT providers (Wang, Lai & Chang, 2016). The impact of OTT service providers on the telecommunication market, consumer trends toward the adoption of OTT services and how they influence operator revenues were analysed by several authors (Sujata et al, 2015;Lutilsky & Ivic, 2016;Gerpott & Meinert, 2016).…”

The aim of this paper is to show rising importance of business model innovation in telecommunication industry. Work gives an overview of telecommunication market, it presents the strategy mobile operators have and challenges they face to adopt to digital world. The main focus is on new business models operators can implement in order to innovate and stay competitive at the market. Cases when operators work in collaboration with startups were analysed and followed by examples from practice. The influence of digitalisation trend on Serbian telecommunication market and how mobile operators respond to it in comparison to other countries were investigated in more detail.
