Common Questions About Firebase SMS in Japan
1) Is using a virtual number allowed by Firebase?
Firebase requires a valid number that can receive OTPs. A PVAPin's Number does precisely that. Always follow Firebase’s terms and use virtual numbers for legitimate verification only.
2) Temporary vs. Rental: What should I choose?
Pick Temporary for one-time sign-ups or quick tests. Choose Rental if you’ll log in frequently, switch devices, or expect to reset your account. Keeping the same line prevents lockouts.
3) What if my OTP doesn’t arrive?
Refresh the inbox and wait up to 90 seconds. If nothing appears, release and pick a new Japan line. Network congestion occurs; switching lines usually resolves the issue.
4) Can I reuse a Temporary number later?
Temporary numbers are single-use by design. For ongoing access to Firebase, rent a number so you can reliably receive future codes on the same line.
5) Will a virtual number impact account security?
Security comes down to your habits. Use strong passwords and enable 2FA. A dedicated rental number can improve continuity when traveling or changing SIMs.
6) Can I verify while abroad?
Yes. Select a working Japan number in PVAPins, then verify Firebase as usual. Rentals provide better continuity if you log in from multiple locations.
