Our Quarterly Average comparison is aimed at providing insight into key trends, as we endeavour to share insight across the UK Enterprise and B2B markets.
Data Usage
UK data usage dropped, after 11 quarters of continuous growth, reflecting the offload to WiFi as Omicron UK stayed at home, including the Festive period.
Data Roaming
Average data usage per user remains an upward trend, as roaming volumes were up across all key regions, particularly Europe.
Voice
Average call duration and total talk times returned to almost peak Covid-19 levels.
Voice IDD & Roaming
It did not matter where customers were in the world, our IDD (International Direct Dial) volumes were up, with roaming volumes showing minor increases, across all regions.
SMS
When in doubt, message! SMS volumes peaked in this quarter for the year.
SIGNUM DNA
A Word About Our Data …
As we have integrated our Signum DNA into Telescope, our Self Service Analytics platform for communications insights, what better way to promote one of the UK’s largest enterprise based expense management research and analysis data warehouses.
We process in excess of 1M active subscriptions, 2.5 petabytes of data usage, 200M voice minutes and 25M SMS events per month:
- All voice volumes are reported in minutes
- All data volumes are reported in Gigabytes (Gb)
- Each SMS/MMS as a single event record
Using a 5 month average (inclusive Nov’19 to Mar’20) as our baseline, we wondered how usage had changed and what our “new normal” looks like.
