Mobile FAQs

Faster upload and download speeds are essential for businesses to operate smoothly, collaborate effectively, and take full advantage of the digital tools and services available in today’s interconnected world. Upload and download speeds are crucial for business broadband for several reasons:

  1. Efficient data transfer: Businesses often deal with large files, such as documents, images, videos, and software updates. Faster upload speeds ensure these files can be quickly and reliably sent to clients, partners, or cloud storage services. Faster download speeds enable businesses to access and retrieve files, documents, and data from external sources efficiently.
  2. Collaborative work: Many businesses rely on cloud-based collaboration tools and platforms to work on projects together. Faster upload speeds enable real-time collaboration, allowing employees to simultaneously edit and share files without delays or disruptions. This promotes productivity and seamless teamwork.
  3. Video conferencing and VoIP: With the rise of remote working and virtual meetings, businesses heavily depend on video conferencing and VoIP services. High upload speeds are essential for transmitting high-quality video and audio streams in real-time, ensuring smooth and uninterrupted communication during virtual meetings and conferences.
  4. Backup and data synchronization: Data backup and synchronisation are critical for businesses to protect their valuable information and ensure data integrity. Faster upload speeds facilitate quick and efficient backup processes, enabling businesses to regularly back up their data without causing significant disruptions to their daily operations.
  5. Cloud services and remote access: Many businesses use cloud-based services, such as software-as-a-service (SaaS) applications and remote server access. Faster download speeds allow businesses to access these services quickly and efficiently, improving overall productivity and minimizing downtime.
  6. Website performance: A business’s online presence is crucial for success. Faster upload speeds are necessary for quickly uploading and updating website content, images, videos, and other media files. Additionally, faster download speeds ensure that visitors can access the website’s content quickly, resulting in a better user experience and improved customer satisfaction.

Static and dynamic IP addresses are two types of Internet Protocol (IP) used by all major websites for email services, file transfers and so on. Static IP addresses remain the same every time you connect to the internet, whereas dynamic IP addresses change every time you connect or send a message over the internet.

Business broadband often provides static IP addresses. This is important for businesses that require remote access to their networks, host servers, or run services that rely on consistent IP addresses.

Home broadband generally uses dynamic IP addresses that change periodically.

If your broadband goes down unexpectedly then please contact our support team on 0344 880 7777. We are here to help you and assist you back so your business can carry on operating.

When choosing the best business broadband deal, you should consider the following:
1. The number of devices using your broadband.
2. The volume of data being uploaded and downloaded.
3. The need for a static IP address.

Visit our broadband speed checker here to see the best deals available to your business. For further assistance call our dedicated team on 0344 880 7777 for expert advice and help when choosing the most suitable option for your business.

Then visit our broadband postcode checker here to see how much faster you could go with Onebill Fibre business broadband.

To get the best from your Onebill Business Broadband connection or Fibre then visit the ‘Support’ section on our website for more information.

To save you time, here’s a short summary with a few things to check:

  • Use your master socket to connect your router
  • Locate your router in the open, and as ‘centrally’ as you can
  • Radiators, pipes and metal objects can really affect your Wi-Fi
  • Keep your router away from other electrical equipment if possible
  • Always leave your router switched on
  • Use an Ethernet cable connection to the router for the best connectivity
  • Don’t have too many users and devices on the same connection

Onebill has a range of broadband packages giving you the flexibility to choose with or without a phone line. When ordering your business broadband, you have the option to add a digital phone line to your package by selecting from the available options.

To see if Ultrafast Business Broadband is available in your area, enter your postcode into our broadband speed checker here to check out what is available to your business. We are the UK’s fastest widely available business broadband provider so can offer you packages with download speeds all the way up to 1000Mbps.

Business fibre is different from other types of internet connections, such as ADSL or cable, because it uses fibre-optic cables instead of copper or coaxial cables. This allows for faster and more reliable internet connectivity, with higher bandwidth and lower latency.

The benefits of business fibre include faster internet speeds, lower latency, greater reliability, and higher bandwidth. This allows businesses to run applications and services that require high-speed internet connectivity, such as video conferencing, cloud computing, and online collaboration.

The cost of business fibre varies depending on the provider, location, and bandwidth requirements. Onebill Business fibre is available in wide range of speeds ranging from 38MB up to 1000MB, cost is reflected by the higher speeds and greater reliability. Click here to check out our range of business broadband deals.

Business ADSL is different from other types of internet connections, such as fibre or cable, because it uses copper telephone lines instead of fibre-optic cables. This can result in slower speeds and less reliability, but it is often less expensive than other types of internet connections. As part of the PSTN switch off in 2023 copper lines are being deactivated, so soon ADSL connections will become extinct.

When choosing a business ADSL provider, it is important to consider factors such as cost, reliability, speed, and customer support. 

You should also research the provider’s reputation and read reviews from other businesses that have used their services.

The cost of business ADSL varies depending on the provider, location, and package options. 

Generally, business ADSL is less expensive than other types of internet connections, but it may not provide the same level of speed and reliability.

The limitations of business ADSL include slower speeds than other types of internet connections, higher latency, and reduced reliability. This can be a problem for businesses that require fast and reliable internet connectivity for their daily operations.

Business ADSL is a type of internet connection that uses legacy technology, copper telephone lines to transmit data at high speeds over the internet. It is typically used by businesses that require low-speed internet connectivity for their daily operations. Copper telephone lines retire in 2023.

Full Fibre Broadband is still rolling out across the UK. It’s not available to everyone just yet, but thousands of businesses are being connected every day. To see if Full Fibre is available to you, head to our Broadband speed checker and see how fast you could go!

Full Fibre Broadband or Fibre to the Premises (FTTP) provides ultrafast speeds up to 1000Mbps. It’s the fastest, most reliable broadband technology available in the UK. That’s up to 13 times faster than Standard Business Fibre and up to 58 times faster than Standard ADSL. FTTP, often known as Full Fibre Broadband, connects your business premises to your local street cabinet with fibre connectivity – not copper wires.

Business Fibre Broadband or Standard Fibre (FTTC) supports superfast speeds of up to 76Mbps. That’s up to 4x faster than standard ADSL Broadband.

FTTC (Fibre to the cabinet), otherwise known as standard fibre, connects your business premises to your street cabinet via legacy copper cables which causes some speed and volume degradation.

Remember the days of dial-up, waiting whilst your computer tried to connect to the internet? Well, Business Broadband has changed all that, with a much faster connection that lets us load and view our content much faster.

Business Broadband provides online access to data-dependent services and the global data network through a wired connection. Then a wireless hub/router lets you share that connection with wireless devices over a protected Wi-Fi network that’s all yours!

Price Promise terms: Proof of an equivalently priced business offer needs to be provided in writing and must be dated within 30 days of the claim in question. It also excludes any limited promotional tariffs within your current contract, and the customer has to be in a position to move from an existing contract or the offer is void. Also, please note that although we’ll happily match a standard product price, we don’t cover extras like delivery charges. This deal cannot be used in conjunction with any other Onebill offer, and excludes existing customers.

Any promotional savings calculations are based on the promotional term stipulated and Onebill Telecom’s current promotions and connection fees (where applicable). Prices against nearest comparable product as per provider websites, excluding competitor promotions are correct at 19/04/2021.

Phone: This comparison is against BT’s standard phone line and daytime rates, and BT phone line unlimited UK call package prices.

Phone & Broadband: This comparison is against BT’s unlimited broadband and line rental with unlimited UK call package, where relevant.

Phone & Fibre: This comparison is against BT’s Superfast Fibre Essential & Digital Phone Line with unlimited UK call package, where relevant.

Any mention of inclusive mobile calls only applies to T-Mobile, Virgin, Orange, Vodafone, EE, O2 and Three.

Free wireless router: the £9.99 charge covers a tracked delivery, configuration and packing.

The actual speed is dependent on the quality of your line, the distance between your connection and the exchange, and the extent to which your local exchange is able to provide this particular speed.

Lines using fibre optic connections are excluded from this comparison.

Any call charge savings have been calculated against BT Business Local and National ppm rate that are not covered within a call package.

Connection fees could apply.

We are able to provide low broadband prices for most exchanges, but this depends on the type of broadband connection obtainable at your particular exchange and the compatibility of your telephone line. Therefore a £3 supplement may be applied in certain scenarios.

Prices shown exclude VAT. Call prices are charged per minute. All offers available to new customers only. Full Onebill terms & conditions apply. Errors and omissions exempt. Manual billing charge of £7.95 per month for non-Direct Debit payments.

Our Business Phone services

We offer two separate Business Phone line packages. Both are tailored to your needs, and are priced accordingly. Our phone service includes, but is not limited to, the following:

Installation or takeover and line rental for one or more fixed telephone lines
A call price package of your choice that enables you to make discounted telephone calls in specified areas.

One phone number for each fixed telephone line that you rent from Onebill
Any other fixed line phone services that we agree to provide you with
Our Business Broadband services

In order to deliver our Business Broadband service, we provide fixed-line, high-speed access to the internet in the UK, as well as a variety of extras like computer security or backup services, all of which are outlined in your confirmation letter.

Broadband speeds

Onebill Business Broadband offers speeds of up to and including 17Mbps. The actual speed you get could vary, depending on a variety of factors, including:

The distance between you and your nearest exchange. In short, the longer your line is, the slower your speed will be
Damage to your phone line, or poor connections between cables
We’ll always provide the absolute fastest speed possible, so if 17Mbps isn’t possible, we’ll provide the closest speed possible to that figure.

Fibre Broadband speeds

Onebill Fibre Broadband offers speeds of up to and including 38Mbps – rising to a possible 76Mbps if you choose our fastest Business Fibre package. As with our standard Business Broadband and Business Phone line deal, Onebill Fibre is offered in two packages that are tailored according to your needs and budget.

Our Fibre products all offer the same superfast broadband speeds, but the speed you ultimately get could vary from the one advertised here. As with ordinary broadband, the speed you receive with Fibre Broadband is determined by things like:

The distance between you and the green cabinet. Fibre optic cables run between your telephone exchange and the green cabinet (you’ll see these on most streets). Your premises is connected to the green cabinet by an ordinary copper phone line, and the longer this line is, the slower your speeds will be.

The condition your telephone line is in. If it’s damaged, worn, or there are broken connections between cables then you will not receive the maximum speeds possible
When do our services start?

Upon signing up to Onebill Business Broadband, Phone or Fibre, you’ll get a welcome pack in the post which contains your contract and activation date – which is the date your service will begin. Activation can begin at any time on that date, right up until midnight.

If you’re switching to Onebill from a different broadband or phone company, we can usually sort this remotely and you won’t need to install a new line. Phone line transfers normally take about ten working days, but the time needed to transfer numbers from other networks can vary – it can take much longer, or in rare cases, may not be possible at all. In these cases, we will, with your agreement, provide a new number (or numbers).

If you need a new line, we will book an engineer to visit your business and they’ll install a line for you. There is always an additional fee for this service.

Using our Business Broadband services

To use our Broadband services, you’ll need a phone line that sits within the BT Openreach network. When you decide to move services to Onebill from a different supplier, we’ll notify your existing provider to explain that we are now providing your services. However, you have to let your current broadband or phone provider know that you want to cancel in the first place.

If you’ve bought Onebill Secure – a computer security service – from us, you need to make sure you uninstall any other computer security software on your relevant devices first.

You’ll receive your free Onebill wireless router when you officially sign up for business broadband. This router is pre-configured and ready to go. Routers bought directly from Onebill include full technical support when needed within the warranty coverage period. Onebill is not responsible and will not cover routers or any other products used in conjunction with Onebill Broadband but bought from a different source.

If you choose a broadband plan that includes a limited broadband data allowance, this allowance will expire at the end of every calendar month and any data you don’t use won’t be carried over into the next month. We’ll let you know when you reach 80% of your broadband usage, and once again when you reach 100%. If you exceed this allowance we reserve the right to charge you more for the subsequent use.

Onebill care levels and associated costs

In addition to Broadband and phone packages, we also provide additional care packages to give you the option of resolving faults and problems extra quickly and conveniently.

These four packages of care are as follows:

Level 1: Free – fault fixed in three working days
Level 2: £1.20 per month for each line – fault fixed in 48 hours
Level 3: £3.95 per month for each line – fault fixed in 24 hours
Level 4: £5.49 per month for each line – fault fixed in 6 hours


If your business relies heavily on phone and/or internet access to function, these care packages are highly recommended. For a small monthly fee, you’ll get some extra assurance that you can get your business back to speed as quickly as possible.
