What's the best Android app for getting free mobile service with data?

Helium Mobile is a mobile service application that offers free cellular connectivity, making it an attractive option for users seeking affordable phone plans. The app provides 3GB of high-speed data per month at no cost, along with calling and texting capabilities. It utilizes eSIM technology, allowing users to set up a virtual SIM card alongside their existing carrier, which is ideal for managing dual numbers or testing service without committing to a paid plan. Reviews indicate that the activation process involves identity verification, which some users find straightforward but others note requires patience. Customer support is responsive, with email assistance available to troubleshoot issues. However, the service relies on T-Mobile's network, so coverage may vary in rural areas. For budget-conscious individuals, students, or those needing a secondary line, Helium Mobile delivers reliable performance without hidden fees. The inclusion of a rewards system, where completing tasks earns gift cards, adds extra value. While not suited for heavy data users beyond the 3GB limit, it excels as a cost-effective solution for basic mobile needs.
