Nextiva: Best for client-facing professionals
My expert opinion
Nextiva stands out as my top VoIP app for iPhone because of its mobile-friendly customer engagement platform. It’s a strong fit for remote teams that need access to voice, video, email, SMS, and social media platforms to connect with customers. Integrating multiple communication channels into a single conversation hub gives you complete visibility into customer interactions.
With the NextivaONE app, you can quickly launch meetings, make calls, and message customers on the go. It also seamlessly integrates customer engagement tools with internal team collaboration, making it easy to involve other departments when needed.
That said, based on my experience, the all-in-one setup may feel a bit heavy for solo users or smaller teams. If you’re just looking for a reliable voice-first VoIP app for iPhone, Ooma is a simpler option with over 50 built-in calling features.
Nextiva pricing
| Plans (per user) | Core | Engage | Scale |
|---|---|---|---|
| Monthly | $23 | $50 | $75 |
| Annually | $15 | $25 |
Standout features
- Team chat: With Nextiva’s secure messaging, you can chat with colleagues instantly. Communicate in real time, screen-share, view your message history, and hop into video calls with one click.
- Do not disturb (DND): Activating this feature automatically ignores all incoming calls. Callers will either hear a busy signal or be rerouted to your voicemail.
- Auto-attendant: Callers will hear an instant automated greeting that lets them choose the person, extension, or department they want to reach. Calls are managed without a human receptionist.

RingCentral: Best call-heavy teams
My expert opinion
RingCentral is my top pick if you’re looking for advanced call features right from your mobile device. It combines desk phone capabilities with modern tools, such as multilevel auto-attendants, call flip, answering rules, and custom call routing. Manage everything from caller ID to automated replies and business hours, so you can stay responsive wherever you work. The best part is that it also works with Apple’s Siri and CarPlay, enabling hands-free calling.
As an industry-leading VoIP phone system, RingCentral truly sets itself apart with its built-in AI technology. With a smart assistant, you can create real-time call notes, draft messages, and summarize video meetings. It also includes AI-powered noise cancellation, so your calls and meetings come through clearly without background distractions.
On the downside, I’ve found that its robust feature set might feel like overkill for startups or small teams. If you just need a basic phone and text system, Grasshopper is a more lightweight alternative.
RingCentral pricing
| Plans (per user) | Core | Advanced | Ultra |
|---|---|---|---|
| Monthly | $30 | $35 | $45 |
| Annually | $20 | $25 | $35 |
| *A customer engagement bundle plan is also available. Contact sales for custom pricing. | |||
Standout features
- Call screening: Manage incoming calls by choosing to accept, decline, block, or send them to voicemail based on the caller ID.
- Call-to-video: Seamlessly upgrade a voice call to a video meeting or share your screen during a one-on-one conversation without disruption.
- Call forwarding: Redirect incoming calls to another office, home, or mobile number so you never miss important calls, no matter where you are.

Zoom Phone: Best for Zoom Meeting users
My expert opinion
Zoom Phone is a great VoIP phone app for iPhone users who already rely on Zoom Meetings and now want to add a business phone system without bringing in a separate VoIP provider. Since it’s built into the Zoom ecosystem, you can easily upgrade a voice call to a Zoom Meeting with just a few taps, without requiring any extra apps or logins.
I also appreciate that Zoom Phone offers flexible pricing options. You can start with a metered plan for light usage, upgrade to an unlimited local calling plan, or select a plan that includes unlimited calls to one international country. This setup makes it easy to scale your phone system as your team grows, without incurring unnecessary minutes.
Zoom’s main limitation is its lack of deep integration with customer-facing tools. If you’re looking for a softphone that works seamlessly with your CRM or business apps, I recommend checking out RingCentral instead. It connects with hundreds of platforms to support more advanced customer workflows.
Zoom Phone pricing
| Plans (per user) | Metered | US & CA Unlimited | Global Select |
|---|---|---|---|
| Monthly | $10.50 | $16 | $25 |
Standout features
- Elevate to meeting: Instantly upgrade a phone call to a full Zoom Meeting without requiring participants to take any extra steps to join.
- Shared line groups: Let team members share access to a group phone number and voicemail, ensuring no call goes unanswered.
- Time tracking: Assign client codes to calls to simplify billing and track call duration for more accurate invoicing.

GoTo Connect: Best for remote sales teams
My expert opinion
GoTo Connect stands out with its all-in-one Customer Experience (CX) suite, designed to give your team every tool they need to support, engage, and retain customers. With omnichannel capabilities such as phone, email, web chat, SMS, and WhatsApp, your agents can manage every interaction from a single shared inbox. I’ve found this valuable for customer-facing teams that need to respond quickly and collaborate easily, even when switching between channels or handling high volumes of inquiries.
Unfortunately, GoTo Connect’s user experience can feel clunky compared to more modern cloud-based communication tools. Nextiva offers a more intuitive alternative with a customer engagement platform that supports multiple channels, including voice, video, SMS, and chat. If a streamlined interface and advanced multi-channel tools are a priority, Nextiva may be the better fit.
GoTo Connect pricing
| Plans (per user) | Phone system | Connect CX | Contact center |
|---|---|---|---|
| Monthly | Custom | Custom | Custom |
Standout features
- Admin GoPilot: Streamlines phone system management by offering built-in AI-powered assistance, giving admins quick access to resources, smart navigation, and self-serve tools within the GoTo Connect interface.
- Virtual fax: Send digital faxes to a traditional fax machine or email inbox, and receive incoming faxes as file attachments directly in your email.
- Conference call bridging: Host phone or video conferences with up to 20 participants, using a dedicated link or by dialing participants and merging them into the call.

Ooma: Best for solopreneurs with dual lines
My expert opinion
Ooma is a top pick for iPhone users seeking a simple, affordable VoIP app that operates like a professional office phone system. The Ooma Office mobile app helps you easily separate business and personal calls, clearly showing when an incoming call is from your Ooma number and displaying key caller details.
It also includes helpful features like call swapping, voicemail prioritization, and robocall blocking. I especially like how the app uses iOS-specific tools to boost efficiency. You can assign icons to contacts based on their line type, use a widget for one-tap access to voicemail and call tools, and minimize screens to multitask during active calls.
That said, Ooma falls short in software integration. If your workflow depends on syncing your phone system with project management platforms or collaboration tools, RingCentral is a better fit, as it supports over 300 business platforms.
Ooma pricing
| Plans (per user) | Essentials | Pro | Pro Plus | Enteprise |
|---|---|---|---|---|
| Monthly | $19.95 | $24.95 | $29.95 | Contact sales for pricing |
Standout features
- Dynamic caller ID: Use custom star codes to switch outbound caller IDs, ideal for assistants or operators calling on behalf of different team members.
- Caller info match: Displays a preview window with details about the caller using their name or number, and lets you link searches to sites like Google, Facebook, or LinkedIn.
- Advanced call logs: Offers detailed call tracking, showing whether calls were answered, missed, sent to voicemail, or disconnected for better visibility and reporting.

Grasshopper: Best for text-focused managers
My expert opinion
Grasshopper is my top choice for businesses that rely heavily on text messaging to connect with customers. Unlike many providers that cap SMS usage, Grasshopper offers unlimited texting, so you can send updates and quick replies without worrying about hitting a limit. To unlock this feature, a one-time $19 fee applies for US numbers to meet Campaign Registry requirements.
Enhance your business messaging with instant-response tools that automatically reply to missed calls from first-time callers, and customize texts with images or links. However, Grasshopper doesn’t support video calls or internal team chat. If you need a more collaborative solution, I recommend Nextiva, which combines calling, messaging, video meetings, and customer engagement tools into a single unified platform.
Grasshopper pricing
| Plans | True Solo | Solo Plus | Small Business |
|---|---|---|---|
| Monthly | $18 | $32 | $70 |
| Annually | $14 | $25 | $55 |
Standout features
- Incoming call control: Customize how and when calls reach you by setting up call flows, screening callers, blocking numbers, ringing multiple devices, and creating business hours schedules.
- Wi-Fi calling: Make and receive calls over a Wi-Fi connection, ideal for areas with weak cell service, while saving on mobile minutes and data.
- Simultaneous call handling: Reduce missed calls by forwarding incoming calls to multiple phone numbers at once, ensuring coverage even during high call volumes.

Talkroute: Best for user-friendly interface
My expert opinion
Talkroute is the best VoIP option for iOS users new to cloud-based calling, offering a simple, easy-to-use app. It’s designed with beginners in mind, offering a clean interface that makes it easy to switch between virtual phone numbers and manage calls while on the go.
Plans start at $19 per month and include essentials like unlimited calling, text messaging, video meetings, and basic features such as call routing, voicemail boxes, custom greetings, and virtual numbers. While it doesn’t offer AI tools, I’ve found its simplicity a plus for teams that want a no-frills solution that just works.
One downside is the lack of support for international calling, which may be limiting if your business works across borders. If global communication is important, Ooma is a better fit, as it supports unlimited calling to the US, Canada, Mexico, and Puerto Rico, along with affordable international rates.
Talkroute pricing
| Plans (per user) | Basic | Plus | Pro | Enterprise |
|---|---|---|---|---|
| Monthly | $19 | $39 | $59 | Custom |
Standout features
- Hours of operation: Define the specific days and times your phone system is active, with the option to set multiple time blocks and custom call routing rules for after-hours.
- Text-to-email: Get your business text messages delivered to your email, complete with the sender’s name, phone number, and message content.
- Submenus: Create additional layers within your main call menu to offer more detailed options, such as different departments or language selections.

How to choose the right VoIP app for iPhone
Finding the best VoIP apps for iPhone means looking beyond just call quality. You’ll want a provider that matches your workflow, budget, and communication needs, especially if your business relies on mobility. Here are the key factors to consider when choosing the right iOS-friendly VoIP solution.
Budget and cost
Monthly pricing for iPhone VoIP apps ranges from $10 to $75 per user, depending on the plan and features. Some providers offer metered or à la carte options, which are ideal for low-call-volume or budget-conscious teams. Reviewing prepaid and pay-as-you-go models can help you avoid paying for more than you need.
Core features
At a minimum, the best VoIP app should include unlimited domestic calling, a softphone interface, voicemail, and basic call handling. Top-rated providers also deliver HD call quality, virtual numbers, and mobile apps. If you need more than the basics, premium plans unlock features like call recording, analytics, video conferencing, and call monitoring.
Third-party integrations
Unified communication platforms often integrate with third-party apps, allowing you to manage everything from a single interface. If your team uses tools like Salesforce, HubSpot, or Google Workspace, make sure your VoIP provider integrates with them. This reduces app switching and improves productivity.
Ease of use
For small teams or solo users, simplicity is key. Look for iPhone apps that are easy to install, intuitive to navigate, and quick to configure. Free trials and live demos can help you get a feel for how the system works before committing.
Customer support
Strong support is essential, especially if you don’t have in-house tech staff. Prioritize providers that offer 24/7 live chat, email, and phone support. A searchable help center or knowledge base is also helpful for troubleshooting on your own.
Security
VoIP runs over the internet, which means you need strong safeguards against cybersecurity threats. Choose a provider that offers enterprise-grade security features like end-to-end encryption, call logging, fraud detection, and secure data storage to protect your communications and customer information.
