Best Second Phone Number Apps 2026: Decision Hub (15-Service Comparison)

By Serhat Doğan · Published May 4, 2026 · 8 min read · Reviewed by TwoLine Editorial

This is the umbrella page for everything I've compared in the second phone number, virtual number, burner, disposable, and verification space in 2026. 15 services, side by side, on what each provider publishes: prices, countries, refund terms, and number type. TwoLine does not publish its own delivery measurements. Most of these services give you a number you keep. TwoLine does not. It sells one-time numbers, so it is the right tool only for a single signup code. Each row in the matrix below links to the deep-dive blog post for that service or category. If you only have 60 seconds, the callout above is the answer; the rest of this page is for picking the right option for your specific situation.

The complete service matrix

Sorted by use-case fit, not alphabetically and not by price. The number type column is our reading of what each provider publishes. Apps decide for themselves whether to accept a number. Treat the column as a guide to the kind of number you are getting, not a promise. Full methodology.

* Number type is our reading of each provider's published information, not an audit of its sourcing. Acceptance varies by app. Strict apps may refuse some number types. Prices as published when this guide was last reviewed. Check the provider's site before you buy. The prepaid SIM row is a general entry, not one provider, so it has no risk score.

Pick by use case (decision tree)

If you can describe what you'll do with the number in one sentence, you can pick the right service in 60 seconds. Find the closest scenario below:

The honest section

I built TwoLine. It shows up in this hub because it fits one sub-niche inside the second phone number search: a single signup code. TwoLine sells one-time numbers for SMS verification. You search for the app, pick a country and a line, see the live price with no account, then buy from your balance. Prices are live and start at $0.39. They vary by app, country and line. A number lasts long enough for one code, usually 10 to 20 minutes, sometimes shorter. The order page shows the exact end time. If no code arrives by the end of the window, the full price returns to your TwoLine balance automatically. You can also cancel after 2 minutes. Once a code has been delivered the purchase is final.

One number is for one code. You cannot keep it, renew it, or reuse it for later logins. That makes TwoLine the wrong tool for any account that may need a future SMS. That's why the decision tree splits the way it does: one code goes to TwoLine, and a number you keep goes to a competitor or to your own SIM. If you do sign up on a one-time number, add email recovery and an authenticator right after signup, and use your own SIM for accounts you must not lose. You can verify the methodology and editorial standards on the founder page and the methodology page.

Every comparison post in this hub also includes a "Where competitor still wins" section that names the scenarios where Hushed, Burner, Sideline, TextVerified, or Grasshopper beats TwoLine on specific axes. The picks above reflect that honest split.

What this hub is not

• Not a guide to anonymity from state-level adversaries — see anonymity layers and consult specialized resources (EFF Surveillance Self-Defense, Tactical Tech, journalist-protection organizations).
• Not legal advice — see legal guide for general framing; consult a lawyer for specific situations.
• Not a banking 2FA solution — most rentals fail bank carrier filters; use a real SIM. TwoLine does not sell numbers for banks, payment apps, money transfer, crypto exchanges, securities accounts, or government identity services. Those are refused at checkout.
• Not an enterprise telecom procurement guide — the Grasshopper / RingCentral tier is consumer/small-business; enterprise procurement involves SLAs, redundancy, and compliance frameworks outside this scope.
