Best VoIP Apps for Android and PC in 2026

Intro Choosing the right VoIP app depends on how you plan to use it: personal international calls, a Windows softphone for remote work, or a lightweight Android dialer that records calls. Below I compare the strongest options for Android and Windows in 2026, call-recording support, SMS and messaging features, and performance. I also point to alternatives like virtual phone numbers and international calling cards when those make sense.

Top VoIP Apps for Android Devices

What you want from a voip app for android varies: lowest cost to call real phone numbers, a simple SIP client, or an app that doubles as a softphone and messaging hub. Here are the top choices by use case.

• Telvio (best for inexpensive international PSTN calls)

  • What it does: Calls landlines and mobile numbers in 200+ countries over WiFi or mobile data.
  • Cost examples: from $0.02/min to the US and about $0.08/min to India.
  • Billing: per-second rates, no connection fees, credits never expire.
  • Convenience: no registration or account required; credit packs start at $1.99 (Starter), $4.99 (Standard), $9.99 (Pro). New installs get 1 free minute.
  • Why choose it: predictable low rates for direct-to-phone calling without a subscription.

• Google Voice (best for U.S. numbers and integrated SMS)

  • Strengths: Free calls within the U.S. to U.S. numbers, voicemail and SMS integration, good Android app.
  • Limitations: full feature set limited to supported regions; works best tied to a Google account.

• Skype / Skype To Phone (best-known global app for PSTN calls)

  • Strengths: mature clients on Android, Windows, and macOS; pay-as-you-go Skype Credit and subscriptions.
  • Limitations: pricing varies by destination; UI includes additional features that may not matter for basic calling.

• Viber / Viber Out (best if you also use Viber messaging)

  • Strengths: free app-to-app calls and messaging; Viber Out lets you call phones at per-minute rates.
  • Limitations: requires separate Viber Out credit for PSTN calls.

• Zoiper, Bria, Linphone (best as SIP softphone clients)

  • Strengths: full SIP support, work with business or personal SIP providers, flexible call routing.
  • Limitations: require SIP account setup; advanced features often behind paid versions.

• WhatsApp / Signal (best for encrypted app-to-app calls)

  • Strengths: excellent voice quality for app-to-app calls; end-to-end encryption.
  • Limitations: cannot call regular phone numbers over the PSTN — only other users of the same app.

Choosing between a dedicated voip phone android client (like Zoiper or Bria) and a calling service (Telvio, Skype, Viber Out) comes down to setup and cost. SIP clients give you control and the ability to connect to business PBXs; calling apps let you pay per minute to reach any phone number without configuring SIP.

VoIP Applications for Windows PCs

Windows users look for softphones that work as a desktop extension of their phone or as a standalone calling tool. Here are strong options for 2026.

• Skype (Windows)

  • Pros: cross-platform, easy PSTN calling with Skype Credit, integrated chat and video.
  • Cons: can feel heavy for simple calling; pricing varies by country.

• Microsoft Teams (Windows)

  • Pros: enterprise features, integrated with Office 365, robust meeting and phone features for businesses.
  • Cons: Teams Phone (PSTN) requires licensing and phone system configuration.

• 3CX / Zoiper / Bria (Windows softphones)

  • Pros: SIP-based softphones that pair with business PBX or hosted SIP providers. Good codec support and call control.
  • Cons: setup requires SIP credentials; some features require paid versions.

• Zoom Phone (Windows)

  • Pros: easy PSTN calling within Zoom ecosystem, strong audio performance.
  • Cons: phone service requires paid plan; better for teams than single users.

• Telvio (Windows via Android emulator or web where supported)

  • Pros: if you need a low-cost, registration-free way to dial international numbers from a PC, Telvio’s simplicity and pay-as-you-go model make it worth considering.
  • Cons: primarily designed for mobile but can be used on PC setups that support Android apps or web dialing where available.

For businesses exploring desktop telephony and more complex setups, review business VoIP phone systems to compare hosted PBX and on-prem options: /compare/business-voip-phone-systems-comparison/. If you mostly place occasional international calls from a desktop, a simple option like Skype or Telvio paired with a headset often works best.

Call Recording Features Compared

Many users need a voip call recorder for compliance, note-taking, or interviews. Call recording support varies widely by app and by platform.

• Built-in recording (apps that offer native recording)

  • Skype: built-in call recording for voice and video calls (not always available in all regions). Recordings are saved to chat and available for a limited time for download.
  • Zoom: cloud or local recording for meetings and phone calls (depending on your plan and permissions).
  • Teams: meeting recording available with proper licensing; direct PSTN call recording depends on admin configuration.
  • 3CX and some business PBXs: often include call recording at the system level, stored on the server.

• Apps with recording add-ons or paid tiers

  • Bria (CounterPath): offers call recording in paid versions.
  • Zoiper: includes recording in Pro versions or with additional plugins.

• No native recording (requires third-party tools)

  • Google Voice: limited recording capability (typically incoming calls only, and you must enable the setting).
  • Viber, WhatsApp, Signal: no built-in PSTN call recording; recordings require device-level audio recording apps on Android (which may be constrained by Android version and app permissions).

Important considerations

• Legal and ethical: laws about recording phone calls vary by country and state. Many places require one-party or two-party consent. Always disclose recording and follow local laws.
• Quality: recordings made server-side (PBX/cloud) typically have higher fidelity and more reliable files than client-side Android screen/audio recording.
• Storage and retrieval: business systems often store recordings on a server with indexing and easy retrieval. Consumer apps usually attach the file to chat or save locally.

If you need a voip phone call recorder on Android, look for SIP clients or business apps that explicitly advertise recording, or choose a hosted provider that offers server-side call recording.

SMS and Messaging Capabilities

If you need a voip sms app or messaging built into your VoIP tool, pick an app whose messaging model matches your use case: PSTN SMS to real phone numbers, app-to-app messaging, or virtual-number SMS.

• PSTN SMS (send SMS to regular phone numbers)

  • Google Voice: supports SMS with a U.S. number and syncs across devices.
  • TextNow, Skype (in some regions historically): have offered SMS to real phone numbers; features and availability can change by country.
  • Dedicated VoIP providers: many business VoIP services include SMS when you buy a virtual number.

• App-to-app messaging (internet messages)

  • WhatsApp, Viber, Signal: excellent for encrypted or feature-rich messaging between users.
  • Skype: supports in-app chat and file sharing across platforms.

• Virtual numbers for SMS

  • If you need SMS to a virtual number for verifications or business, see our virtual phone numbers guide: /guide/virtual-phone-numbers-guide/ and options for free virtual numbers: /guide/free-virtual-phone-numbers/.
  • Business VoIP systems and many SIP/VoIP providers sell virtual numbers with SMS-capable routing.

• Telvio and SMS

  • Telvio focuses on calling real phone numbers over WiFi or mobile data. If you need integrated SMS to phone numbers, check for providers that explicitly list SMS/short code support or pair Telvio voice calling with a separate SMS-capable virtual number provider.

Choosing a voip sms app requires checking coverage and carrier rules in the countries you operate in. For international sign-up or verification, make sure the virtual number provider supports receiving the type of verification SMS you need.

How to pick

• If you call many different international PSTN numbers and want simple pricing and no account setup, an app like Telvio delivers direct-to-phone calling with transparent per-second billing and low starting credit.
• If you need desktop softphone features tied to company systems, choose SIP clients or business solutions; review business comparisons: /compare/business-voip-phone-systems-comparison/.
• If you need SMS-capable numbers for verification or business messaging, combine a voice app with a virtual-number provider; see /guide/virtual-phone-numbers-guide/.

Final tips

• Test call quality before committing: most apps or providers let you try a short call or provide sample credit packs (Telvio offers a free minute on install).
• Check codecs and network settings if you use SIP clients on Android — choosing Opus or G.711 often improves quality.
• Watch for background battery use; some SIP clients let you increase registration intervals to save battery.
