I have been using Trafficmaster Oracle / Freeway since 1999, but the service ended last year
I am looking for a mobile phone, solely for use with the Trafficmaster App as this is now the only option

I have asked Trafficmaster three times, but they won't answer the question, so here goes...

The App costs :
Free to download and first 30 days access, then
£0.69 per 3 months
£1.99 per 12 months
£4.99 lifetime

What method does the Application use to connect to the service?
Does the mobile phone require to have specific formats of communication installed / active (such as GPRS, 4G, GPS, etc) ?

This is essential to establish what type of device and contract service I should look at
Any and all advice welcome
