Case Study

Operator

A mobile operator in Africa with 29 million subscribers.

Campaign Scope

5 tariffs plans monitored during one quarter

Case Description:

The operator offers roaming bundles (30–120 mins to home country) whilst roaming. Araxxe testing showed discounts were applied separately for VoLTE and 2G/3G calls.

This allowed customers to exceed their bundle—e.g., using 60 mins on a 30-min plan.

Issues were not identified by standard roaming controls.

Root cause: 

• Limited testing was carried out.
• Testing focused on VoLTE scenarios.
• No testing was carried out on legacy services.
• Changes implemented to bill VoLTE impacted billing of legacy services.
