Some models of mobile phone will need the right adaptor to work completely - e.g. audio input and output at the same time.
You may simply need an adaptor to get your handset fully functional!
The first port of call when seeking information on adaptors is to visit our website which lists all the phones we have tried and tested with our products. This list can be found here - http://www.nativeunion.com/adaptors
If your phone isn't listed don't despair! Most new phones that have been released lately do not require an adaptor to connect to your handset, and many of the ones that do require the N4 (for some of the 3.5mm audio jacks) to connect correctly.
Does your phone have a 3.5mm headphone socket on it anywhere? If so, please try plugging the handset directly into your phone, and there's a high chance it will work straight away!
If your phone does not have a 3.5mm connection, please try and find out which connection your phone is equipped with for connecting to external handsets and we will try and find out which adaptor you need.
If you are unsure please try to refer to the manual for more details of it.
Please email in if you have any questions.
