Second phone number apps and alternatives, compared

Updated 2026-09-30 · By the ZuteSIP team (ZuteSIP Inc.)

Short answer: Most second-number apps focus on the US, Canada and a few other markets and live inside a mobile app. ZuteSIP supplies real mobile, local and toll-free numbers in 181 countries with SIP credentials, a browser web dialer and call forwarding, for one flat price per number. The pages below compare each option fact by fact.

Choosing a second phone number depends on where you need the number, how you want to use it and how you prefer to pay. These comparisons stick to public, sourced facts about each service so you can pick the right tool, even when that tool is not ours.

How we compare services

Every comparison on this page follows our editorial policy: facts about other services come from their official websites, help centers or app store listings, each linked in the sources list and dated September 2026. If we could not verify something, we left it out rather than guess.

Each page covers what the other service is, a side-by-side table, when that service is the better choice, when ZuteSIP fits better, and how to get a ZuteSIP number if you decide to switch.

The main differences at a glance

  • Country coverage: consumer apps such as Burner, 2ndLine, Hushed and MySudo centre on North America and a handful of other markets; ZuteSIP offers numbers in 181 countries.
  • How you use the number: most apps are mobile-first; ZuteSIP works in a browser web dialer, in any SIP softphone or PBX, and through call forwarding to any phone.
  • Pricing model: app subscriptions, ad-supported free tiers or pay-as-you-go APIs, versus one flat ZuteSIP price from $1.80 per month billed yearly for every number type in every country.
  • Payment: app-store or card billing elsewhere; ZuteSIP accepts USDT or USDC only.

What ZuteSIP does not try to be

ZuteSIP does not ship mobile apps, voicemail, call recording, a customer API or number porting. If one of those is essential, the comparison pages point out which alternative covers it. What ZuteSIP does provide is the real number plus SIP credentials, so you can connect it to the softphone or phone system you already prefer.

Getting a ZuteSIP number

  1. Sign up with an email address.
  2. Choose a country and mobile, local or toll-free number.
  3. Pay in USDT or USDC; most numbers activate within minutes.
  4. Call from the web dialer, add the SIP credentials to a softphone, or forward calls to any phone.
