Round by round

1. Round 1💰 Price for a Single LineT-Mobile wins
   T-Mobile6/10

   $50/mo

   Experience Essentials Saver, single line, direct from T-Mobile

   • 5-year price-lock guarantee on the plan rate

   • Taxes and fees now billed separately

   Source: T-Mobile pricing data

   Google Fi5/10

   $50-$65/mo

   Unlimited Standard/Premium, base price roughly doubled since 2021 launch

   • Legacy Flexible plan offers per-GB pay-as-you-go pricing
   • Same $50/mo as T-Mobile's base tier for the same underlying network

   Source: Google Fi pricing data

   T-Mobile and Fi's base tiers cost the same — but Fi is paying that price to ride T-Mobile's own network secondhand.

2. Round 2📡 Network RealityT-Mobile wins
   T-Mobile9/10

   Largest 5G footprint

   T-Mobile's own mid-band + low-band nationwide network

   • Owns the largest 5G footprint in the country
   • No reseller layer between you and the network

   Source: T-Mobile network data

   Google Fi5/10

   T-Mobile + shrinking US Cellular

   Fi's 'multi-network' pitch is increasingly just T-Mobile after the Sprint/US Cellular consolidation

   • Genuine dual-network switching still exists on supported devices
   • Secondary US Cellular partner is shrinking as T-Mobile absorbs it

   Source: Google Fi network data

   T-Mobile is the network; Google Fi is mostly a rebrand of the same network with an extra layer.

3. Round 3📱 Device CompatibilityT-Mobile wins
   T-Mobile8/10

   No device-tiered features

   BYOD-friendly, feature set identical across compatible devices

   • No feature gap between device types
   • No Pixel-specific network-switching feature to speak of

   Source: T-Mobile device data

   Google Fi4/10

   Network switching is Pixel-only

   • Full network-switching feature works great on Pixel phones
   • Non-Pixel/iPhone users lose the signature switching feature entirely

   T-Mobile treats every compatible phone the same; Fi quietly gives non-Pixel owners a lesser version of its own product.

4. Round 4🌍 Perks & International RoamingGoogle Fi wins
   T-Mobile5/10

   30GB Canada/Mexico

   Included on Experience Beyond top tier; T-Satellite for basic texting

   • 30GB high-speed data in Canada/Mexico on top tier
   • T-Satellite satellite texting for coverage gaps
   • No flat-rate international data plan for global travel

   Source: T-Mobile plan data

   Google Fi9/10

   50GB in 200+ countries

   Included free on Unlimited Premium, plus calls to 50+ countries

   • 50GB high-speed international data in 200+ countries included
   • 6 months YouTube Premium + 100GB Google One bundled
   • 'Unlimited abroad' use requires periodic return to the US

   Source: Google Fi plan data

   T-Mobile covers North America; Google Fi is genuinely built for the rest of the world.

5. Round 5🧩 Plan Structure & ValueT-Mobile wins
   T-Mobile7/10

   5-year price lock

   Rate-lock guarantee on Experience plans

   • 5-year price-lock guarantee on plan rate
   • Taxes/fees now itemized separately, raising effective cost

   Source: T-Mobile plan data

   Google Fi4/10

   $20 → $50/mo since 2021

   Base unlimited tier roughly doubled; Bill Protection Flexible plan being phased out

   • Legacy Bill Protection auto-caps overage costs
   • Base tier price roughly doubled since 2021 launch
   • Most customer-friendly plan being phased out

   Source: Google Fi pricing data

   T-Mobile's pricing has stayed predictable; Fi's has crept upward while quietly retiring its most customer-friendly plan.

6. Round 6⭐ Customer Service & TrustGoogle Fi wins
   T-Mobile4/10

   1.4/5 Trustpilot, 8,200+ reviews

   • Nationwide retail stores for in-person help
   • 24/7 phone support available
   • 1.4/5 Trustpilot from 8,200+ reviews

   Google Fi3/10

   1.3-1.4/5 Trustpilot

   • Deep integration with Google account/services for support tracking
   • 1.3-1.4/5 Trustpilot
   • No retail stores — support is entirely online/app-based

   Both score in the same dismal range — but T-Mobile at least backs its number with retail stores to walk into.
