O2 Broadband?

What is O2 Broadband?

O2 Broadband is a new service from O2 which will give you broadband internet access on the move using our practical USB Modem. If you have a laptop, PC or Mac just plug in the USB modem into your USB port to connect.

Do I need a landline to use this service?

No landline is required to get O2 Broadband. You just need your computer and the modem to get started.

What’s in the box?

  • The O2 Broadband modem
  • The set up guide

The network coverage

What is the actual O2 coverage ?

Check the coverage using our O2 Broadband Coverage Map.

What happens if I move in and out of O2 Broadband coverage area?

The USB Modem will automatically connect to the available 3G or GPRS/EDGE networks until the next O2 Broadband network is available. The switch between networks is seamless.

Usage allowance

How much can I download and upload?

With our O2 Clear Broadband price plans you get either 5GB, 7.5GB or 10GB usage allowance depending on your plan. Usage is calculated in Megabytes (MB) and Gigabytes (GB) -where 1GB equals 1,000MB. As an example a typical music track is 5MB, and a 2 hour DVD quality film is 1GB. Uploading to the Internet (eg. sending photos and emails) also counts towards your allowance.

If I go over my usage allowance?

If you are on any of our O2 Clear Broadband plans you will pay 2c overage for each MB downloaded outside your usage allowance. If you are on our older plans i.e. ‘Broadband on the Move’ or ‘Broadband out and about’ and go over your usage allowance then O2 can implement the Fair Usage Policy. Please see below.

Fair Usage policy?

The Fair Usage policy for O2 'Broadband on the Move' is designed to ensure customers have a good broadband experience. The policy enables O2 to manage excessive use by individual customers as this can impact the general speed and reliability of the Broadband service. The fair usage threshold/limit for O2 Broadband customers is 10GB per month. If you exceed this threshold/limit then O2 reserve the right to introduce an excess usage charge of 10c per MB. We will notify you in advance as to when the excess usage charge will be applied. If you then continue to exceed the fair usage threshold then O2 reserve the right to modify, suspend or terminate your service.

How will I know if I’ve gone over my usage allowance?

You can check your usage regularly on o2.ie in ‘My Account’. Go to the section ‘Details since last bill’ and your usage will be dated and labelled as Broadband.

Installation & Troubleshooting

The modem seems not to work properly. What can I do?

If your modem does not work check this steps:

  • Try to connect the USB Modem to your laptop using the long cable in the package. There are 2 reasons for the extra cable. The 1st is to optimize reception. Very often a computer may be under a table and the reception may not be good. So the longer cable allows you to put the modem on a window shelf for better reception. The 2nd reason is power. Older laptops may not supply enough power through the normal USB cable. The O2 broadband cable has 2 USB connectors allowing users to connect to 2 USB ports to provide the power needed for the USB modem to work properly and maximise signal quality.
  • Try to uninstall any previous USB modem software as this may cause hardware conflicts.

What if the Install Wizard does not automatically start?

If the installation wizard does not automatically start, simply open Windows Explorer
(Start>Programs>Accessories>Windows Explorer), browse to the Mobile Connect drive (E: or F:) and double-click on Autorun.exe. Your computer might be set up such that ‘My computer’ folder is on the desktop, if so select ‘My Computer’ and browse to Mobile Connect drive (E:F) as above

What if the short cable does not work?

If the short cable does not work there will not be a flashing green light on the face of the modem. You will need to use the double ended cable by inserting the two larger ends into two available USB ports.

Make sure that the O2 USB Modem is in coverage and has a network signal this can be checked on the desktop software

Check that the O2 SIM card is correctly inserted to the modem
