Features to Look for in Mobile Phone Plans for a Small Business

If you’re a small business owner, you know how important it is to have a mobile phone plan that can work with your business. But there are so many options out there! How do you choose?

Look for the following features in a business plan to decide if they will suit your small business.

Hotspot Function

One of the first things to consider is whether or not the plan offers hotspot functionality.

Hotspot capability means sharing your mobile data connection with other devices. This can be useful if you want to use your phone’s internet connection but don’t have access to WiFi—for example, if you’re out in the field or don’t have time to stop at a coffee shop or other public place with WiFi available.

Using a hotspot allows your employees to share the connection from their phone with any other device connected via Bluetooth or USB cable. This includes laptops and tablets as well as smartphones and other mobile devices. Hotspots are particularly useful for business employees who frequently travel or conduct fieldwork on their company’s behalf.

Email and Surfing

A business phone plan should be able to provide you with email and surfing capabilities.

Email is an essential part of any business, and having access to your email on the go can help you stay organised and respond to messages quickly.

Similarly, browsing the web on your phone is a great way to keep up with social media and other important information about your business. So you don’t have to wait until you get home or back at the office.

Number of Lines

The number of lines is important because it tells you how many employees will use the phone plan. The more lines you have, the more employees can use the same phone plan.

If you have only one line, then only one employee can use the phone plan. This may not be a problem for some businesses since they may not have many employees or if their employees work from home or remotely.

If you have multiple lines, there are several options for managing them. One option is to have all employees share one account with unlimited minutes and texts across all devices (phone numbers). Another option is to give each employee their own line to make calls from any device they choose.

A multi line phone plan offers increased flexibility for a growing business. So ensure that your business phone plan includes multiple lines for peace of mind.

International Calling

A business phone plan that includes international calling could be worth the investment. It would pay off if your business deals with clients located outside of your country or if you regularly collaborate with people overseas.

Look for international calling packages that include free minutes, calls to certain countries, and low per-minute rates on the more popular call destinations.

WiFi Calling

One feature that might be particularly useful for a small business is WiFi calling. This feature allows you to make calls using a WiFi connection instead of through cellular service.

This means that even if there’s no cell signal in the area where your employees are working, they’ll still be able to stay connected with each other and call out through their cell phones.

Unlimited Calls

Another feature you should consider is unlimited calls and talk time. You’ll want this option if some of your employees spend much of their day talking on their phones with clients or other team members.

Unlimited talk time means there will never be any limit on how long they can call during a single billing cycle. So no surprises when it comes time to pay your bill!

Unlimited Data

Data usage is variable from month to month, and the last thing you want is to run out of data storage space at a critical moment.

You may need to send large files or use video conferencing tools like Skype or Google Hangouts, which can quickly eat up your data allowance.

Unlimited plans also mean you won’t be surprised by an unexpected bill or have to pay overages when your usage exceeds your plan limits.

Hence, ensure that your plan has unlimited data allowance, so you don’t run out halfway through the month!


Nowadays, mobile phones have gone beyond being a fashion or luxury item. They’re as important a tool to run your small business as your website or PC.

This guide features 5 of the best mobile phone plans for a small business in the UK. We hope it will help you find the best mobile phone service for the best deal possible.
