Background:
BELL WIRELESS RESULTS
REVENUES
Bell Wireless operating revenues increased by 3.7% in 2019, compared to 2018, driven by greater postpaid and prepaid service revenues and higher product revenues.
Service revenues increased by 2.5% in 2019, compared to last year, driven by: • Continued growth in our postpaid and prepaid subscriber base coupled with rate increases • A greater mix of customers subscribing to higher-value monthly plans including unlimited data plans launched in June 2019 • The favourable year-over-year impact from the 2018 CRTC retroactive decision on wireless domestic wholesale roaming rates
These factors were partly offset by: • Greater sales of premium handsets and more customers subscribing to higher-value monthly plans • Lower data and voice overages driven by increased customer adoption of monthly plans with higher data allotments and richer voice plans
Product revenues increased by 6.6% in 2019, compared to last year, driven by greater sales of premium handsets and the impact of higher-value rate plans in our sales mix.
