NGT Lite is a mobile application that connects to the UK’s Next Generation Text (NGT) Service. More information at

For any support queries or feedback, please contact the NGT Helpdesk through:


Once installed, you should link your UK fixed or mobile phone number in NGT Lite. When linked, the app can create a connection over the Internet which works in parallel to your phone call to enable voice and real-time text to be combined into a single phone conversation. This enables you, as someone who is hearing or speech-impaired, to communicate with other phone users either directly, if they are also using the app, or via the NGT Relay if they’re a telephone user.

NGT Lite is designed to work with individual fixed and mobile phone numbers. Organisations wanting to use NGT Lite must ensure that the Calling Line Identification (CLI) for outgoing calls is unique to the phone being used. The CLI must also match the incoming phone number for the NGT App to be able to receive calls.

After linking NGT Lite to your phone number, you can make a call by starting the app and then, using your phone, dialling 18001 followed the number you’re calling. As your phone call connects via the NGT Service, a Join Call dialogue pops up on the app. Once you join the call, any text announcements or conversation appears in the app and you can type your reply. You can also use your phone to speak directly to the other person or hear their voice.

Quick guides

Setting up:
•Download and install the NGT Lite app
•Open NGT Lite
•In the Options page, add your full UK telephone number (e.g. 0791…)
•Using your phone, dial 0800 500 888
•You’ll get a text announcement saying the app is linked to your phone number

Making a call:
•Open NGT Lite, the green icon will show that you’re connected
•Make your call by dialling 18001 followed by the full telephone number you wish to call
•Switch back to the app and click Join Call
•You can now type and read, speak and read, or type and hear your conversation, either direct or via the NGT Relay

Answering a call:
•Caller dials 18002 followed by your phone number
•Phone rings
•Open NGT Lite and click Join Call
•You can now type and read your conversation, either direct or via the NGT Relay
•If you want to speak and read, or type and hear your conversation, answer the phone call before clicking Join Call

If you’d like to verify the correct functionality of the app, after linking your phone number in NGT Lite, you can dial the NGT Helpline on 0800 500 888 from your phone and connect to that call with the app for a test run.

Important Notes:
- Do not leave the app while connected to a call, switching NGT Lite to run in the background may suspend functionality shortly and disconnect you from your call.
- To use your smartphone to make or answer a phone call and run NGT Lite at the same time, you must make sure your smartphone supports simultaneous voice and data or, if not, you’ll need to have a Wi-Fi connection.

Can not scroll

Have been having issues now with trying to scroll down to read text during a call, it’s like it freezes at the top of the ‘conversation’ (start of the call)

Checking the help section is no help... I’m so disappointed cause it was such a good app..

Deaf people left behind again

I tried using this app a couple of years ago and had to delete it as it was so faffy to use and it wa so time consuming and confusing I ended up with a massive phone bill. Tried installing to see if it’s improved and I’m massively disappointed to see things are still the same. Considering this is marketed to many companies as the means to communicate with deaf customers and vice versa that this is the way deaf people can make calls I think it’s awful. The app needs starting again from scratch in my opinion. In the mean time I’ll be deleting this and relying on friends instead. Might be worth speaking to deaf people next time and testing the app before pushing it out as a suggestion

App really need to be updated to the lastest version of apple.

I have just come off ngt on a call, your app was causing problems, I was not able to see what I was typing as soon it get to the bottom of the screen, I has to keep closing my keyboard to see if my message was ok. I has to cancel the call with customer service because I couldn’t see what they were saying, it was the same with the relay assistant! I am not happy as I use this service to book interpreters for my hospital appointments.

I find that I’m typing every words and keep making mistakes means I have to go back and edit and start again, it’s takes a while. I rather not do this and use autocorrect which would be a big improvement, autocapitalise as well. Also quicker.

Let people use their keyboard and allow autocorrect without having to manual type every letters.

The app hasn’t been updated in 3 year, I will have to look elsewhere for something similar as people use this service to help them contact doctors, appointments etc. I can’t use this on my Samsung note 10 plus as it doesn’t work at all. Not happy at all....
