Network sunsets are a significant undertaking for operators. However, the process is not without risk, and delays can occur due to slow uptake of replacement devices.
When embarking on its 2G sunset, Entel wanted to ensure no one was left behind. The operator offered free phone replacements to 2G users living far away from its stores, and those affected by the 2023 wildfires in Chile. Entel delivered the phones directly to those communities.
A significant challenge was customer outreach. Some 89% of beneficiaries were prepaid customers, making them challenging to contact. Preliminary surveys also revealed that many 2G users were older adults who did not want a smartphone. In response, Entel offered customers feature phones, which were better suited to their needs.
Entel’s multichannel approach – which included special call centres, SMS reminders, local media advertisements and municipal partnerships – has resulted in the delivery of more than 4,100 phones to date, accounting for 42% of 2G users impacted.
Entel’s 2G sunset project has led to the decommissioning of 1,993 2G sites, resulting in a 4.5% decrease in energy consumption (approximately 13 GWh per year) and a reduction in emissions of 3,961 tonnes of CO2. The project also included an ambitious recycling programme; this aimed for 40% equipment recycling but as of June 2024 had achieved 72%, recovering 34.8 kilograms of metal and preventing 2,135 kilograms of CO2 emissions.
