I’m having problems making/receiving calls
If you're having problems with your home phone service there are some simple checks you can do to try to find out what's wrong.

Always check the power cable is connected to the landline base unit and that it's plugged in properly.

If you're using a cordless phone make sure it's charged up; there's usually a battery indicator displayed on the handset screen.

Once you're happy that the handset has charge and all the units are plugged in properly, please answer these questions and if necessary carry out the simple checks.


  • Is there a dial tone?
  • Can you receive calls?Have you paid your bills?
  • Have you tested the phone with all other telephone equipment unplugged?
  • Have you tested the socket with another phone?
  • Have you tested the phone in another socket?


If you’re still having issues making or receiving calls please answer these questions, please scroll down to Report a fault tab and fill out the form and our team will do all they can to fix the issue as quickly as possible.

Our team may get in touch with you because the nature of the issue needs you to be in the property to carry out some tests on the equipment which will help the team get to the root of the issue.

Will my landline work during a power-cut?
Your landline won't work during a power cut because the Optical Network Termination (ONT) needs electricity to function and operate a landline service.

If you rely on your landline and have a corded telephone our engineers can fit a battery back-up unit which will enable the line to work should a power-cut happen. Please Contact Us to arrange your engineer visit.

If you have Community Alarm unit, we will fit a battery back-up free of charge when we install the fibre line to your home.

  • If you’re still having issues making or receiving calls it could be because of a problem with the network.

If the fault is on the JT network we'll send out an engineer to fix it, and you won’t be charged.

Some faults may be caused by a problem with the internal wiring or equipment at the property. JT is responsible for the line up to, and including the NTP (Network Terminating Point) - the point at which our network cable enters your home or premises. If an engineer visits and the source of the fault is proved to be your internal wiring or equipment, you will be charged for the visit.

Can I have a community alarm?
What is a Community Alarm or Horizon unit?

A Community Alarm, or Horizon unit, are devices which can be activated to call the emergency services. They’re installed in the homes of those who are frail, elderly people who live alone in the community and for people with disabilities. More information can be found here.

How much will it cost?

If a client is on income support benefit there is no charge. Otherwise the charges are based on the rental of £29.70 per quarter, plus GST, which is payable to JT Global.

Application for an alarm

The method of applying for an alarm is initially through the person's GP or Family Nursing and Home Care. The application is then passed to the Community Alarm Coordinator, who will then arrange for an alarm to be supplied and fitted and will explain the operation of the alarm to the person and where necessary, to any family and friends who are key-holders.

The Alarm

The alarm system consists of a base unit with an integral telephone built in, together with a pendant which the person wears round their neck and depresses a red button to request assistance. Wrist type pendants are also available.

JT cannot support landline customers with a Lifeline alarm unit with Sure. They are therefore not eligible for JT landline.

Scam & Fraud Awareness - Marketing ‘Cold’ Calling
Sales and marketing organisations may try to contact you to out of the blue to push all manner of products and services.

Scam & Fraud Awareness - Stolen Phones
If you lose your phone or it is stolen and it lands in the wrong hands the implications to you may be more than just losing your mobile device. If access is gained to your phone you could be opening yourself up to the following risks:
  • The personal information stored on the device could be used for further criminal acts (e.g. identity theft, subscriber fraud etc.)
  • Even if the device is locked the SIM could be removed and used to make calls that will end up on your next bill.
If your phone is stolen on-island or while you’re away on holiday, please contact us as soon as possible on 01534 882882 to ensure that your service is suspended and no further charges are incurred. Many people think disabling the device is sufficient, but this does not stop fraudsters from using your SIM card in another phone and racking up huge bills at your expense. In order to protect your data ensure that there is a secure PIN on both your device and SIM and make sure that you keep your device software up to date.
