Questions about iPhone/Apple Watch emergency calls

by Poster May 30, 2025 6

As we all know, after the iPhone is pressed for a long time or pressed the power-on button five times in a row, an emergency call will be triggered, or similar services will also be triggered in car accidents and falls. But I haven't found the exact statement for some questions. I wonder if you have seen relevant discussions or official documents. 1. When the user is located in country A, the data card of country B is inserted into the mobile phone, and the area in the mobile phone settings is country C, then in case of emergency, which country is the emergency service called? 2. Under the same circumstances, if wireless is connected and Wi-Fi calling is enabled, which country is the emergency service called? 3. If the emergency service called is not from the country to which it belongs, is there any mechanism to automatically transfer to the local emergency service (such as calling 110 with a mainland mobile phone card in the United States)? If so, is it 100% triggered (does not involve whether there is commercial cooperation between the two countries or the two operators)? Thank you ~

There is no actual measurement here, but you can guess from another angle As we all know, all mobile phones themselves have an emergency call, and that emergency call uses a base station, and the emergency call originally has to have a network to work. The network here refers to the base station coverage even if your device has "no signal" It is inferred that Apple also makes emergency calls based on the base station. In this case, Apple should be able to know your approximate physical country and use the emergency number of that country first

@ Anonymous2253 # 1 Thank you, I really don't know much about the principle behind it, and it's hard for me to test when it comes to emergency services... If this is the case, I wonder if the airplane mode is enabled and Wi-Fi Calling is enabled can be met at the same time. If so, there will be another problem hahaha.

This I think of a question, ask what technology is so developed today, why don't emergency alarm calls merge all numbers, such as common 110, 119, 112, 120, 122, 911, 999, etc. can be merged, anyone can directly dial free of charge even if there is no sim card or signal, there will be no problem of usage habits. The original number can also be directly transferred to dial, and many accidents need multi-party coordination. If someone is injured, ambulance and fire should come at the same time. If a car spontaneously ignites, ambulance, traffic police, fire also come at the same time. After the merger, it will not forget to dial a certain number. It seems that only one emergency alarm call in North America and a few areas

@ Anonymous7338 This thing cannot be changed, just like voltage, bolt shape, and left and right traffic. The social infrastructure after it was decided a long time ago is based on this rule

@ Anonymous7338 # 3 I forgot where I read it. The mechanism of one call is diverted by the operator according to demand, while multiple calls omit this step, which can theoretically improve efficiency. At the same time, in order to prevent people from not remembering the phone number, making the wrong phone number, and having multiple needs (such as alarm + first aid), different numbers in many provinces are linked at present.
