You’ll find a full suite of tools to keep your business running smoothly if you operate a contact centre. From a features standpoint, Mighty Call is one of the most capable VoIP providers in the UK.

You can set up different options for different departments, and you can even use custom recordings. It takes your brand to the next level and ensures that customers have a pleasant experience when they call your business.

What separates MightyCall from other providers is that it can integrate with almost all CRM seamlessly. This includes Zapier or ZOHO without any problems. However, connecting with some software applications will require API, which requires advanced IT knowledge.

Pricing

Although all prices are in USD, MightyCall’s pricing is very simple and straightforward. The company offers three business plans: the Small Team plan for $15.00/month per user, the Business plan for $20.00/month per user, and the Enterprise plan for $150.00/month.

4. Voiply — The Cheapest VoIP Service With Unlimited Calling

Voiply promises a 99.99% uptime, which is pretty good. Uptime is the time during which a system is operational. The average uptime for VoIP providers is about 95%. This means that Voiply’s uptime is significantly higher than most other providers, and its customers don’t have to worry about their VoIP service going down frequently.

Voiply only has two plans, Residential and Business; both offer unlimited calling. The best thing about Voiply is that it’s one of the cheapest VoIP services right now. The Residential plan starts at $7.16/month, and the Business Plan starts at only $11.16/month (when paid annually).

However, the Residential plan and its adapter are only available in the United States, Canada, and Puerto Rico. If you live elsewhere, you’ll have to buy the Business plan

Unlike other service providers, Voiply’s auto-attendant is free. An auto-attendant is an answering machine that gives the caller a menu of options to choose from. This is a valuable feature for businesses, as it can help save time by handling customer inquiries without the need for a live operator.

Voiply also offers free voicemail-to-email, which is another great feature for businesses. Voicemail-to-email allows you to receive your voicemails as audio files in your email inbox. This way, you can listen to them at your convenience, and you won’t have to worry about missing any important messages.

To summarize, Voiply is one of the best and cheapest VoIP providers with unlimited calling. If you’re looking for a VoIP provider that can give you great features at a very affordable price, then Voiply is the right choice for you.

Pricing

As mentioned, Voiply only has two plans: Residential ($7.16) and Business ($11.16). Both plans offer unlimited calling to 50+ counties.

This is one of the few providers that offers unlimited voice calls outside the US. If you opt to get the Residential plan, you will get a free adapter.

5. Phone.com — Freelancers’ Best Choice For Unlimited VoIP

Phone.com offers unlimited local and long-distance calling, but only for the US, Canada, and Puerto Rico. Their second-tier plan is just $15.99.

Phone.com integrates easily with popular apps and services like Salesforce, Google Voice, Dropbox, and more. However, some customers report that the quality of Phone.com’s integration with Salesforce isn’t as good as other VoIP providers.

Still, we think Phone.com is the best unlimited VoIP service for freelancers because of its low price, lack of contracts, and excellent customer service.

If you are a remote worker or a freelancer, you know how important it is to have a dependable VoIP service.

There are no contracts or hidden fees with Phone.com—you can cancel at any time without penalty. Plus, their customer service is available 24/7 to help you with anything you need.

The $15.99 Plus plan is perfect for freelancers because it doesn’t just offer unlimited calls; they also equipped it with video-conferencing for up to 25 participants and allows for custom greetings.

7 Key Benefits of Unlimited VoIP Calling

Although mobile communications have seen vast improvements over the last several years, many businesses are still using landlines to make calls. In addition to being expensive, these traditional phone lines can be inflexible and unreliable. VoIP systems have become a popular alternative for business owners who want to improve their communication without breaking the bank. Here are seven key benefits of using an unlimited VoIP service.

Cost-effective

One of the most significant advantages of VoIP is that it’s much cheaper than traditional phone lines. With VoIP, you only need to pay for the internet connection and hardware, which is a fraction of the cost of landlines. In addition, VoIP calls are often free or very low-cost so that you can save even more money on your monthly bill.

Flexible

VoIP systems are highly flexible, so you can quickly scale up or down as your business needs change. If you need to add more lines, you can do so without any problems. And if you need to reduce the number of lines, you can do that as well. With traditional phone lines, it’s much more challenging to make changes like this.

Reliable

VoIP systems are just as reliable as traditional phone lines, and in some cases, they’re even more reliable. With VoIP, you don’t have to worry about the line going down due to a power outage or bad weather. And if your internet connection is down, you can still make calls using your VoIP system.

Mobile

VoIP systems are perfect for businesses that need to be mobile. With VoIP, you can make and receive calls on any device, anywhere in the world. All you need is an internet connection. So if you have employees who work from home or travel often, VoIP is a great option.

Better sound quality

VoIP calls are clear and crisp, with little to no background noise. This is because VoIP uses digital signals instead of analogue signals like traditional phone lines. So you can rest assured that your calls will be crystal clear.

Advanced features

VoIP systems come with a variety of advanced features that can improve your communication, such as caller ID, call waiting, voicemail, and more. These features can be beneficial for businesses that need to stay organized and efficient.

Easy to use

VoIP systems are designed to be user-friendly, so you’ll be able to set up and use your system with little to no training. And if you ever have any problems, most VoIP providers offer excellent customer support.

How We Chose the Best Unlimited UK VoIP Providers

With so many VoIP providers on the market, it can be hard to decide which is best for your business. To help you make a decision, we considered a number of factors to make our recommendations for the best unlimited VoIP providers in the UK.

Reliability

The first factor we considered was reliability. VoIP is an internet-based technology, which means that it is subject to the same potential problems as any other internet service. However, a good VoIP provider will have systems in place to minimize these problems and keep your service running smoothly.

We looked at customer reviews and independent expert opinions to get a sense of each provider’s reputation for reliability. We also took into account the company’s history and track record.

Ease of use

The second factor we considered was the ease of use. VoIP can be complex, and the last thing you want is a service that is difficult to set up and use. For example, some VoIP providers require you to have a specialized router, while others work with your existing equipment.

So, we looked for providers that offer simple, straightforward services that are easy to set up and use.

Value for money

The third factor we considered was value for money. There are a lot of VoIP providers out there, and they all charge different prices for their services. We took into account the cost of the service, as well as the features and benefits included in each package.

We also looked at any special offers or discounts that were available. For example, some providers offer free calls to certain countries, while others include a certain number of free minutes in their packages.

Customer support

A good VoIP provider offers excellent customer support, so you can get help when needed. Even in the case of providers who promise a 99.99% uptime, things can (and do) occasionally go wrong.

There are providers who have been in business for many years and have a reputation for excellent customer service, while others are newer to the market and may not have the same level of experience.

The LTE package does require a subscription fee, but it’ll work even through power outages thanks to a battery backup system.

Purchasing a handset through Ooma is a painless process, all you need to do is choose where you want your Ooma Telo sent to and enter in some basic payment details. Best of all, it’s free shipping! You can also send the devices back to Ooma if you decide you want to use their 30-day money-back guarantee.

Shipping can take several days depending on your location, but once you have the Ooma device in your hands the rest of the process takes minutes to complete.

Step 2 — Register your Ooma device

Before you can use your Ooma device, you’ll need to register it to activate the subscription plan. Ooma is free by default, but you’ll have to enter some basic details about your usage before you can get started.

To register your Ooma device, go to “Login” on the homepage and then select “My Ooma Telo”. You’ll be taken to a login page, from there you’ll have to click “Activate my new account” to get to the registration page.

The activation code is located on the bottom of your Ooma router, which is helpfully pointed out during the activation process.

After this step, you’ll be asked to enter some basic details about your location and billing if you’re going with one of Ooma’s paid plans, but it’s all pretty straightforward.

Step 3 — Figure Out Your Needs and Follow Their Guide

Finally, you’ll want to decide on everything you need to set up based on your plan and business needs. There’s hundreds of different options, which would be hard to cover in a single guide.

Once you’re done with the setup phase, all you have to do is upgrade to the World package to receive calls in the UK and you’re ready to go!
