Google debuts Project Fi group plan to add up to 5 people for $15/month per user for texts and calls
Starting today, Google's Project Fi now offers a group plan. Fi users can now have up to six people on one plan, inviting new members at any time for $15 per month.
Context & Ripple Effects
When Google launched Project Fi in 2015 as an MVNO running on Sprint and T-Mobile at $20/month plus $10/GB, it was a single-line experiment limited to the Nexus 6. The service has since widened its device footprint with tablet and data-only device support, and the new group plan is the next step: up to six people on one account at $15/month per user for texts and calls, with members invited at any time.
That matters because Fi's original pitch was usage-based pricing for early adopters, while the bulk of the US market buys shared family plans from the major carriers. A group option moves Google's MVNO toward the pricing structure households actually shop for.
First-order effects
- Fi subscribers can consolidate a household onto one bill at $15/user for calls and texts, cutting the per-line cost versus six separate $20/month base plans.
- Sprint and T-Mobile, whose networks host Fi traffic, gain incremental lines through Google without running their own acquisition funnel for those users.
Second-order effects
- Group billing raises switching costs per household rather than per person, making Fi stickier against the carriers' own family-plan promotions.
- The move pressures Google to keep rounding out conventional plan features — a path that later produced the $60 monthly bill cap and eventually a traditional unlimited plan.
Third-order effects
- If the pattern holds, Google's MVNO evolves from an early-adopter experiment into a full-range carrier competitor, with Google controlling the customer relationship while leasing network capacity — a structure that shifts brand loyalty away from the underlying networks.
The trend: MVNOs are graduating from niche single-line offerings to full household plan portfolios, using group pricing to compete with the carriers whose networks they ride on.
