Is Line2 a good app for business use in 2026?

Line2 holds a 4.4 out of 5 rating on the iOS App Store with over 30,000 reviews, and the Android app sits around 3.6. For a small- business second line in the US or Canada, it works. The Pro plan at $16 monthly on annual billing adds auto-attendant, after-hours call handling, and dial-by-name directory, which competes with OpenPhone, Grasshopper, and Google Voice for Business. The weaknesses cited in reviews are the 7-day trial (shorter than the 14 to 30 days most competitors offer), occasional sync issues between iOS and desktop clients, and metered international rates even on Pro. For a single-user second line you mostly use for texting and US calls, Standard at $10 a month is the right tier.

Is Line2 VoIP or does it use the cellular network?

Line2 is VoIP. Every call placed through the Line2 app routes through the internet using SIP and RTP protocols, the same technology behind Zoom, OpenPhone, and Grasshopper. Line2 does not have a carrier interconnect that lets it ride your phone's native dialer like a traditional cell line. This matters for two reasons: Line2 calls fail without WiFi or cellular data, and Line2 does not support 911 the way a regular mobile line does (you have to register an address for emergency routing in the app). The Line2 number is portable to other VoIP services but generally cannot be ported to a regular mobile carrier as a primary line.

Which is better for a US second line, Google Voice or Sideline?

Google Voice is free for personal use and integrates with Gmail and Google Workspace; Sideline charges $9.99 monthly with stronger business features like team numbers and shared voicemail. Google Voice's drawback is the US-only signup requirement: you need a US phone number and US IP at registration, which excludes most expats setting up from abroad. Sideline accepts foreign-billing-address signups and ships an app-based US number to anyone with App Store access. For solo personal use already in the US, Google Voice wins on price. For business team use or for non-US-resident signup, Sideline is the more flexible option. Both compete with Line2 Standard.

What are the alternatives to Line2 worth considering?

The closest US-second-line alternatives are OpenPhone ($15 monthly, strong CRM integrations), Grasshopper ($28 monthly, the veteran option for solo business), Sideline ($9.99 monthly, simpler than Line2), Google Voice (free personal, $10 business), and TextNow (free with ads). For voice-only with no permanent number, Talk360 and KeepCalling beat Line2 on raw per-minute pricing at $0.01 a minute. For inbound texting plus business automation, OpenPhone is the most-recommended Line2 alternative in 2026. For occasional outbound calling from abroad without any subscription, browser-based WorldDialer starts at $0.04 a minute to the US and covers 214 countries, avoiding the monthly cost entirely.

Can I port my existing US mobile number into Line2?

Yes. Line2 supports porting in any US or Canada mobile or VoIP number through a standard LNP request, which usually completes in 5 to 10 business days. You submit the port request inside the Line2 app or web portal with your current carrier name, account number, account PIN, and the exact billing name on file. During the port window you keep your current service active; switching happens at the cutover moment. Toll-free 800-series numbers and some Google Voice numbers cannot be ported to Line2; check the Line2 support page for the current exclusion list. Port-in is free; there is no setup fee or porting charge as of 2026.

Line2 vs WorldDialer: Honest Comparison for 2026

Line2 charges $10 to $22 per user per month for a permanent US phone number with unlimited US and Canada calling. WorldDialer charges per minute for outbound calls to 214 countries, with no subscription required, no app, and no permanent number assigned. The honest comparison: these aren't the same product. Line2 sells you a phone line. WorldDialer sells you the call you're making right now.

Here's the head-to-head.

The Quick Answer

Line2 and WorldDialer solve overlapping but different problems. Line2 is a long-established second-line phone service from Ziff Davis. You pick a US or Canada phone number, install the app on up to 5 devices, and you've got a separate line for business or personal use with unlimited US/CA calling and texting on a monthly subscription. WorldDialer is a browser-only dialer for outbound calling: 214 countries, pay-per-minute, no subscription required, no permanent number.

Feature | Line2 | WorldDialer

Monthly subscription | $10-22/user/mo | $0

US calling | Unlimited (included) | Pay-per-min

Second US phone number | Yes | No (dialer only)

International outbound (e.g., Mexico, India) | Pro plan + metered | 214 countries, metered per-minute

Free trial | 7 days | Pay-as-you-go credits

Two different shapes of service. Line2 is a permanent line. WorldDialer is a per-call tool. Pick based on which shape you actually need.

What Each Service Actually Does

Line2 gives you a US or Canada phone number that rings on your devices anywhere you have internet. WorldDialer gives you a browser tab that dials out when you need it.

That's the whole difference, and it determines almost every other choice in this comparison.

The honest disqualifications go both ways. If you want a permanent US phone number people can call you on — for business, for inbound texts, for a stable line in your name — WorldDialer can't help. Line2 wins. If you only call US numbers occasionally from abroad and don't need a permanent line, paying Line2 $10 to $22 a month for a phone number that mostly sits idle is overpriced for your use. WorldDialer wins. And if you need to call Mexico, India or the UK, both services get you there. Line2 puts international outbound behind the Pro plan and meters every minute; WorldDialer meters it too, at 4¢ a minute to Mexico and the UK and under 8¢ to India.

WorldDialer's pitch is narrow on purpose: we do one direction in your browser, with no app, no account, and no recurring charge. If your needs run wider than that, Line2 is the better fit and we're not going to pretend otherwise.

Line2 Pricing in 2026

Line2 charges $10 per user per month on annual billing or $15 per user per month on monthly billing for the Standard plan. The Pro plan is $16 annual or $22 monthly. Both plans include unlimited US and Canada calling and texting. International outbound is a different story.

Plan | Annual billing | Monthly billing | What's included | International

Standard | $10/user/mo | $15/user/mo | Unlimited US/CA calls + texts | Not included

Pro | $16/user/mo | $22/user/mo | + auto-attendant, after-hours handling, multi-line management | Available, metered per-minute

A few honest notes on Line2.

The Standard plan is good value for daily US/CA users. Unlimited US and Canada calling plus texting for $120/year on annual billing is a fair price for a permanent second line. If you're using a Line2 number every day for business calls and texts, the per-minute math on any pay-per-use service stops being competitive. Standard wins.

The Pro plan adds business-line features. Auto-attendant, simultaneous call forwarding, after-hours call handling, dial-by-name directory, multi-line management. If you're running a small business off the line, Pro is the right tier. If you're just using it as a personal second number, you're paying for features you won't use.

The 7-day free trial is short. Industry norms run 14 to 30 days. Line2's 7 days is on the tighter end. Worth knowing before you sign up.

Line2 is a Ziff Davis brand. Ziff Davis (NASDAQ: ZD) is a public mid-cap media and tech holding. The brand has been around since the early iPhone era under the same product name, originally as Toktumi. App Store rating sits around 4.4/5. Real product, established team, not a fly-by-night service.

The Per-Minute Math vs The Subscription Math

Line2's annual cost is fixed: $120/year at the cheapest tier, regardless of how many calls you make. WorldDialer's cost scales with usage: pay per call, nothing if you don't call.

The break-even point isn't subtle.

Usage scenario | Line2 Standard (annual billing) | WorldDialer

30 min/year (3 calls × 10 min) | $120/year | Less

100 min/year | $120/year | Less

5 hr/month to US/CA (60 hr/year) | $120/year | More

10 hr/month to US/CA (120 hr/year) | $120/year | More

Plus texting | Included | Not supported

At low usage, the subscription is overhead you didn't need to pay. At sustained usage, the subscription locks in a fixed price that pay-per-minute can't beat. The crossover lands around 250 minutes a month: at $0.04 a minute that's $120 a year, which is Line2 Standard on annual billing to the dollar.

The honest summary: if your annual US calling fits inside a handful of hours, you're paying Line2 for a permanent line you're barely using. If your US calling runs into the hundreds of minutes a month, Line2's flat subscription is the better deal.

When Line2 Wins

Line2 wins if you want a permanent US or Canada phone number. A separate line for business. A way to keep your personal number off business contacts. A stable inbound line you can hand out.

Permanent second line for business or personal separation. This is Line2's core product-market fit. You get a real US number, calls ring on your phone and laptop, texts come in to the same line. WorldDialer doesn't try to compete here at all.

Daily US/CA calling and texting. Standard plan's unlimited US/CA at $10/month annual is the right price for sustained use. At more than a few hours of calling a month, the flat rate beats per-minute math on most services.

Receiving calls and texts on a US number. WorldDialer is outbound-only. It doesn't assign you a phone number, so nobody can call you back. If you need inbound, you need Line2.

Multi-device sync. Line2 syncs across up to 5 devices — iPhone, Android, Mac, PC. Pick up a call on your laptop, finish it on your phone. WorldDialer works from any browser, but doesn't sync state across devices in the same way.

Existing Line2 users with the workflow dialed in. If you have a Line2 account that's working and a number people already have, there's no reason to switch. The Standard plan is honestly priced for what it does.

When WorldDialer Wins

WorldDialer wins if you only make outbound calls occasionally — a few times a year from abroad — and you don't want to pay $10 to $22 every month for a line you barely use.

The case for WorldDialer over Line2 turns on whether you actually need a permanent phone line in the first place.

What WorldDialer offers instead of a subscription:

No subscription required, no auto-renew
No app to install
No account to maintain beyond payment
No US phone number to provision (you don't need one)
Works in any browser, from any device
Pay per call — done after the call

WorldDialer charges per call. After the call, the transaction is done. There's no monthly bill, no app on your phone, no account to log back into six months later when you need to call the IRS or a US bank again.

For the typical user this serves — someone abroad calling US institutions or family a handful of times a year — Line2's $120/year minimum is overhead you didn't need to pay. Pay-per-call beats pay-per-month at low volume, every time.

For US-only callers who value that pattern, this is the cheapest international calling app math when you account for actual use rather than features you won't need.

The International Calling Question

Line2's international outbound requires the Pro plan AND/OR a pay-as-you-go international credit add-on, and it's metered per-minute even on Pro. WorldDialer meters international minutes too, with no plan to upgrade to first.

The difference here is structural.

Line2's Standard plan does not include international outbound. If you sign up at $10/month thinking you'll be calling Mexico or India, you'll hit the wall fast. International calling requires either upgrading to Pro or buying pay-as-you-go international credit on top of your subscription. Even on Pro, every international minute is metered at Line2's rate-table prices, country by country. Multiple reviewers cite this as a recurring frustration.

WorldDialer's version is simpler. Every destination is metered, there's no plan to upgrade to first, and the rates sit on one page: 4¢ a minute to Mexico and the UK, 6.48¢ to Indian mobiles, 27.3¢ to the Philippines. The product is one direction: outbound, in a browser, pay per call. If your route is an expensive one, you'll see it before you dial.

If you call Mexico, India or the UK, both services can place the call. Line2 makes you carry a subscription to get there; WorldDialer charges for the minute and stops. At low volume WorldDialer is cheaper on both the US and those routes, and Line2's advantage stays where it always was: the permanent number, the inbound calls, the texts.

Decision Rule

Want a permanent US phone number with inbound calling and texts: Line2. Call a few times a year from abroad: WorldDialer. Occasional calls to Mexico, India or the UK: WorldDialer, at 4¢ to Mexico and the UK and under 8¢ to India. Need those calls on a business line every day: Line2 Pro. Already happy with Line2: stay there.

Your Situation | Pick

Want a permanent US phone number | Line2

Call US several hours a month | Line2 Standard

Receive US calls and texts | Line2

Call US a few times a year from abroad | WorldDialer

Hate subscriptions and apps | WorldDialer

Need a business line that also dials Mexico, India, UK | Line2 Pro (metered per minute)

Already happy with Line2 | Stay with Line2

That's the comparison. Pick the one that matches what you actually do.

Skip the Subscription If You Don't Need It

If you only make a few calls from abroad each year and you don't want to pay $10 to $22 a month for a phone line you'll barely use, WorldDialer is built for that exact use case.

WorldDialer: pay-per-minute outbound calling to 214 countries. Browser-based. No subscription required, no app, no account beyond payment, no number to maintain.

If you want a permanent US phone line — for business, for inbound, for texting — Line2 is the right product. We'll be here if your needs change.
