Same video as posted last year, same old misinformation.
Factually incorrect – almost everything except that dialling 999 or 112 will get you through to the emergency services.
Last time around I said:
To expand. There is no difference or priority between 999 and 112 calls in the UK. All mobile phones with keypad lock / PIN on them allow 999 as well as 112 (as well as 911). The emergencySMS service actually uses 999 officially although 112 works too. The cell towers all have spare capacity for emergency calls beyond normal voice calls (hence you sometimes see “emergency calls only” on your phone) and if there’s lots of people also calling 999 / 112 then you’re SOL. Ofcom apparently ensured a few years ago that you can roam across UK networks to make an emergency call, even if your own network is out of reach (subject of course to your phone working on that network’s frequency – almost all do now).
999 or 112 gets you to the same place – one of the central call-answering services (the ones who ask you “which service?”). Based on your landline address or a rough location from cell triangulation they should always put you through to the appropriate local fire/police/ambulance control centre.
