China

 Overview of an emergency service 

The 112 in China can work from a mobile phone through the GSM network, which will automatically forward the call to the nearest 118 emergency call centre in/within the region/province. But it is not known yet if it is possible to call 112 in China from a mobile phone without a sim card to be forwarded to 118 or whether it's either possible to call 118 directly from a mobile phone without a sim card that supports 118 as an emergency number.
