Cape is $5/month more than Google Fi Unlimited Premium per line. That premium gets you IMSI rotation, SIM swap protection, SS7 lock, and private payment that Google Fi Unlimited Premium doesn't offer at any price tier.
Which one should you pick?
Pick Cape if…
- You want IMSI rotation, SIM swap protection, SS7 lock. Google Fi Unlimited Premium does not offer these at any tier.
- Your phone number is the account-recovery path for your email and bank, so the carrier holding it is part of your threat model.
- Coverage is not the tradeoff here. Cape rides T-Mobile, the same network Google Fi Unlimited Premium runs on, so signal where you live should be comparable.
- You can find a few referrals. Each one takes $20/month off for both parties, up to five, and four covers Cape's $70 entirely.
Pick Google Fi Unlimited Premium if…
- Monthly cost is the deciding factor. It is $5/month cheaper per line, or $60/year, before any referrals.
- You are buying for a household. Google Fi Unlimited Premium drops to $40/line at five lines, while Cape stays flat at $70 and discounts only through referrals.
- You specifically need 100GB high-speed data, 50GB hotspot, International data in 200+ countries.
