The Best Android & iOS Mobile VoIP Apps for Your Business

Paul Kilinga
Best Android & iOS VoIP Apps
VoIP technology has completely transformed the way businesses and people communicate, and when these services branched out to mobile coverage, it was an even bigger game changer. Today, there are dedicated apps specifically for this task, and the best VoIP apps come with unique features like messaging services, transcripts, and call handling.

The advantage of these applications is that they work the same way that traditional VoIP services do, but now with the added convenience of mobility (and that comes without wasting your minutes). 

With the help of some of the best mobile VoIP providers in the country, we’ve outlined everything you need to know to make smart choices for your business needs.

What is Mobile VoIP for Business?

Mobile Voice over Internet Protocol (mVoIP) refers to the use of packet-switching technology to digitize audio signals, compress them, and send them to an end user as a voice call through a mobile phone network—3G, 4G, and 5G—or WiFi. mVoIP works through an app available in Android, iOS, and other smartphone stores or recommended for download by the VoIP service provider.

Just as households might use mVoIP to benefit from affordable, WiFi enabled calling services, so too might businesses. Indeed, mVoIP provides companies with an additional solution for business communication on the go, enabling you to connect to both local and international calls. Businesses can also utilize other mVoIP features, such as video and conference calls to enhance collaboration at work.

You’ll need to register your VoIP service account details on your mobile device to begin using it. While there are many convenient mVoIP features, mobile devices cannot replace your VoIP desk phone completely. There may be some missing features (depending on your service provider), such as reliable internet connectivity in various locations.

How Do VoIP Apps Improve Business Communications?

VoIP apps boost business communications by offering cost-effective accessibility, usability, and portability. Unlike a VoIP desk phone, mVoIP offers alternative internet connections like WiFi, keeping communication lines open throughout the day, which is vital for business success.

Mobile phone VoIP apps enable faster interactions, as audio packets are digitized and sent much quicker than on a desk phone. You can always tell when a customer or another contact is online or busy, ensuring that you can plan a business call at the appropriate time. 

With mVoIP, a company can get new employees up and running by providing them with a VoIP-connected device to access contacts and connect to meetings from any location. Mobile phones also save on bandwidth costs by operating within the data plan you paid for, meaning you won’t have to pay extra for costly plans. You can also take advantage of the BYOD (Bring Your Own Device) option to cut costs. BYOD means employees can use their personal devices to download and install the VoIP app for business use. 

In addition, mVoIP offers access to communication features, such as voicemail to email transcription, which converts your voicemails into text, enabling you to send emails faster. Your registered VoIP business number will remain constant no matter your mobile device, meaning that contacts can reach you on the same business line. Furthermore, you’ll save time on registering phone numbers afresh since the VoIP apps maintain your contact information across platforms.

Important Mobile VoIP Features You Must Know

Mobile VoIP has many helpful features for your business:


mVoIP is portable, cost-friendly, and compatible with many mobile devices. Some of its services, such as international calls, can be offered free depending on the VoIP provider. It can integrate with other software, such as Customer Relationship Management (CRM) tools, making it easier to solve different business challenges seamlessly. 

Audio and HD-Video Calls

You can make and receive audio, and HD-quality video calls on your mobile device from anywhere with an internet connection. You can also record phone calls or listen to voicemails on the app. The linked devices feature enables you to connect multiple devices, ensuring they ring simultaneously if a call comes in. This prevents your team from getting missed calls.

The call-flip feature can transfer an ongoing call from your VoIP desk phone or computer software to your mobile device without dropping the call. Thus, you can continue communicating with your contact on the move.


Mobile VoIP enables you to send or receive instant messages, which is valuable for collaboration or getting information faster. You can use the voicemail-to-text feature to read the message or send it as an email without needing to recreate it.

Status Availability

VoIP apps display statuses, which means you can tell when one of your contacts is online before scheduling a call with them. Furthermore, if your team is stationed across various geographic locations, you can confirm a team member’s availability by checking the app.

Group Chats and Online Meetings

For teams to collaborate well, mVoIP enables members who aren't at the office to join chats and meetings to discuss projects. Many VoIP providers focus on secure communications, meaning you can share files safely from anywhere.

Popular Features of Mobile VoIP

Mobile VoIP has come a long way since simple voice calls over the internet. Here’s a look at the many features that can benefit you and your business:

Link separate offices

If you have more than one office, this is a great way of creating a seamless working environment between them. It also helps alleviate time differences for global workers, as staff can take calls or meetings from home or on the move. Check with your provider to see if it offers PBX capabilities, helping you create a private branch exchange for your staff, not only for all of your physical offices, but also on mobile.

Appear ‘always on’

Working hours can become a thing of the past when your mobile phone is also your office phone. Any time a customer has a query or a concern, they have a direct line straight to the correct staff member. VoIP providers allow users to create extensions and groups of extensions so that calls can be routed effectively. If your business wants some downtime, you can also create personalized voicemails or greetings which explain opening hours or redirect accordingly.


Conferencing capabilities are improving all the time, and can include video chat, instant messaging, and a conference floor monitor system. This last tool allows admin to manage invitations to meetings, questions coming in, and options like muting certain members.

Screen sharing

This means that IT support or other colleagues can see your problem or example at a glance from their own screen. Mobile VoIP also allows for video and file sharing, all over the internet, and without a third party middleman.


Customer relationship management tools which can be integrated into the top business VoIP solutions include Salesforce, Act, Zoho, Microsoft Dynamics, and Oracle. These allow you to keep track of your customer data, your incoming and outgoing calls, capture call notes, and explore real-time accountability.


Whether it’s customer service, office staff or teleworkers, your business deserves to get the most out of its employees. Your business VoIP can support this, with integrations with popular productivity software such as G-suite or Office 365. Amongst others, Salesforce Desk and Zendesk can support customer service, while software such as Clio or ConnectWise are great for business management.


Security is paramount when it comes to business VoIP, both for mobile and desktop. The latest trends in security include powerful ID authentication tools, end-to-end encryption, and Transport Layer Security (TLS) or Secure Real-Time Transport Protocol (SRTP) encryption.

Professional look

For small businesses especially, having your business number routed directly to you wherever you are is priceless. Some companies allow you to create unique local numbers around the globe, so that your customers always feel that you are a professional local presence for them. Whether your user is calling from Japan or Australia, they will be able to use a unique local area coded number to call your mobile directly.

Mobile VoIP Quality and Performance 

The biggest concern that customers have when it comes to mobile VoIP is reliability. This is key when it comes to the image of your business and your interactions with both customers and staff alike. 

While free mobile VoIP services, or those intended for personal use, may include issues such as latency errors or weak signal, mobile business VoIPs is a whole different ball game. The most important reason is Quality of Service or QoS. All VoIP companies are required to meet QoS protocols which include an evaluation of jitter, latency and delay, ensuring a certain amount of resources are allocated to voice calls.

Don’t forget to factor in bandwidth, though. If you’re using WiFi, your call is only as good as the bandwidth it is using. Working from a crowded coffee shop full of people using the network might slow you down.

It’s also worth remembering that unlike wired-in VoIP on desktop and in the office, your data charges may vary from provider to provider. While the calls themselves may not be charged, the use of the internet might well be. Users will need to be aware of how much mobile data they have to play with and how much will be used, especially with data-heavy tasks such as video calls. Of course, using home WiFi or any other connection can bring those costs down.

Other common concerns you may want to talk to your mobile VoIP provider about include:

  • Your VoIP works seamlessly between desktop and mobile, updating in real time, for example when it comes to reporting or client management.
  • The ability of the mobile VoIP app to work in the background, allowing you to continue other work or check email while you take part in a call.
  • Degradation issues. Can you limit the bandwidth for certain parts of the interaction, for example giving more resources to voice over video quality, or helping to send a file more quickly?
