Can I use TextNow to call without a US phone number?

Yes, TextNow assigns you a free US phone number when you sign up, so you don't need an existing one. You watch ads in exchange for free calls and texts to US and Canadian numbers. The catch is call quality depends on your internet connection, and some users report account suspensions if TextNow detects you signing in from outside North America. If that happens, a paid pay-as-you-go option like World Dialer at $0.04/minute or Viber Out at around $0.012/minute is a more stable fallback.

Which pay-as-you-go app has the lowest rate to US numbers?

Viber Out has the lowest published rate at around $0.012/minute to US landlines, but you need the Viber messaging app installed to use it. Talk360 raised its US rate to $0.04/minute in July 2025, matching World Dialer. Yolla and Rebtel publish their own US rates, worth checking directly. World Dialer is the only one here you can run from a browser tab.

Do any free calling apps work without a Google or Apple account?

Most don't. Google Voice requires a Google account and usually a US phone number to verify. TextNow needs an email signup but no Google or Apple account, and it issues you a free US number on registration. If you want to skip Google and Apple, browser-based services like World Dialer take a credit card and dial from a browser tab, though you give up the "free" part for $0.04/minute transparency.

How much credit should I buy first on a pay-as-you-go app?

Start with $5 to $10. That's enough to test call quality to your most-called number before committing more. Most apps including World Dialer, Yolla, and Talk360 let you top up in small increments. A $5 balance buys 125 minutes at $0.04/minute, which covers a few real conversations. If quality holds up and the expiration policy isn't a trap, scale up. If credits expire in 90 days, don't load more than you'll use in that window.

Best Calling Apps Without Monthly Subscription (2026)

Subscription calling apps charge you $30/month whether you make 100 calls or zero. If you only call internationally a few times a year, that's a $360 annual tax on 5 phone calls.

That math is absurd. Subscriptions are for Netflix. Phone calls are for credit.

Here are the best pay-as-you-go calling apps that charge you only for calls you actually make.

Free Calling Apps (If You Qualify)

Google Voice and TextNow offer free calls to US numbers, but with limitations worth knowing.

Google Voice gives you a free US phone number and free calls to any US or Canadian number. The catch: you need a Google account and typically need an existing US phone number to set it up. If you're an American abroad with a Google account, this works great. If you're trying to sign up from scratch outside the US, you'll likely hit roadblocks.

TextNow offers free calls and texts to US and Canada in exchange for watching ads. You get a free phone number, but call quality depends on your internet connection, and the ads can get annoying. It's genuinely free, though—no credit card required.

Both apps work best for people who already have US phone numbers or are comfortable with ad-supported services. If neither fits, you'll need a paid option.

Best Pay-As-You-Go Calling Apps

For most occasional callers, a pay-as-you-go app beats subscriptions by hundreds of dollars per year. Here are the top options.

World Dialer charges $0.04/minute to US landlines and works entirely in your browser—no app download required. You buy credit, make calls, and that's it. Credits never expire. If you want the simplest possible setup and don't want another app on your phone, this is the one.

Yolla offers rates starting around $0.02/minute with good call quality. It requires an app download, but the interface is clean and straightforward. Your credit becomes inactive after 365 days of no use—but it doesn't expire permanently, it just needs reactivation. Good choice if you prefer a dedicated mobile app.

Talk360 charges $0.04/minute to the US and works in 196 countries. Credits expire after 12 months, but any top-up resets the clock. Solid reliability and wide coverage make it a safe bet for people calling multiple destinations.

Rebtel stands out because it can route calls through local phone lines, not just the internet. If you're in an area with spotty WiFi, Rebtel still works. Rates are around $0.028/minute pay-as-you-go, with optional unlimited country plans if you call one destination frequently.

Viber Out offers some of the lowest rates—around $0.012/minute to US numbers—but you need the Viber app installed. If you already use Viber for messaging, adding Viber Out credit is painless. If you don't use Viber, downloading a messaging app just to make calls might feel like overkill.

Watch Out for Credit Expiration Policies

Some apps expire your unused credits after 90-180 days. That $10 you added "just in case"? Gone.

Credit expiration is the hidden gotcha in pay-as-you-go calling. You buy $20 of credit for emergencies, forget about it for six months, and discover your balance is zero when you actually need it.

Best policies (credits never expire):

World Dialer
CallSky.io

Good policies (12 months, activity resets clock):

Talk360 (12-month expiry, resets with any top-up)
Yolla (becomes inactive after 1 year of no use, but can be reactivated)

Watch out for:

Apps with 90-180 day expiration (read the fine print before adding credit)
Skype—it's retired as of May 5, 2025. Don't add new credits there. If you have existing Skype credit, you can use it through Microsoft Teams.

Before you buy credit on any app, check the expiration policy. A slightly higher per-minute rate with non-expiring credits often saves money compared to a cheaper rate where your credits vanish.

Which App Should You Use?

Your best choice depends on how often you call and whether you want to install an app.

If free is fine: Google Voice works if you have a US-based Google account. TextNow works if you can tolerate ads. Both are legitimately free for US and Canada calls.

If you want occasional calls with no app download: World Dialer runs in your browser. No installation, no app permissions, no storage space. Open the site, enter the number, make the call.

If you prefer a mobile app: Yolla and Talk360 both offer good interfaces, reasonable rates, and decent credit expiration policies. Yolla edges out on rate, Talk360 on coverage.

If you have bad internet: Rebtel can route calls through phone lines instead of VoIP, which helps in areas with unreliable WiFi.

If you already use Viber: Viber Out has excellent rates. Adding calling credit takes 30 seconds.

Most of these apps let you try a small credit purchase first—usually $5-10. Test the call quality to your most-called number before committing to a larger balance.

The Bottom Math

You make 5 international calls a year. A $30/month subscription costs you $72 per call. Pay-as-you-go apps charge you for actual calls—maybe $1.00 for a 25-minute conversation.

Subscriptions make sense for call centers. For occasional callers, they're a tax on forgetfulness. These apps exist so you don't pay it.
