Case Study: Drimsim enables affordable travel connectivity and in-app VoIP with IceRock

Drimsim launches a companion SIM app in 6 months with IceRock

The customer, Drimsim, needed a companion mobile application for their SIM card service to allow travelers to use cellular data and make calls at local rates abroad. They engaged the vendor, IceRock, to develop this iOS and Android app, which required integration with their physical SIM cards and support for multiple languages.

IceRock developed the solution, which included country-specific rate charts, expense tracking, and VoIP calls to reduce costs. They integrated with numerous external services and built a robust tech support system. The resulting app successfully works in tandem with the Drimsim SIM card, providing users with clear cost breakdowns and cheap in-app calls. The vendor, IceRock, reported that the app achieved 100,000 downloads.
