This is a common misconception. A lot of folks tend to believe that mobile phone jammers do block emergency calls in case of crucial emergency situations. They couldn't be more wrong.
Did you know that your regular smartphones can still make emergency calls even without a sim in them?
That’s how most phones are designed so that in case you’re in trouble and there’s no connection to your registered network provider, you can still call 911 and other emergency services.
As a precautionary safety measure, you are always able to connect to an emergency service. It's a standard internationally implemented. For example, in The US and other countries, there is a law that requires that, even when completely out of service, cell phones must be able to make emergency calls.
Similar to a roaming service when you are abroad, your phone is allowed to connect to any other network available to place an emergency call. 911 in the US, 999 in the UK, and 112 in Europe WILL override any roaming list, or non-registration, and will force the phone to attempt to connect to any network it can pick up.
The basic understanding is that if you have a cell phone, ALL providers must accept the 911 call and forward it to the call center. Mobile phones are designed to permit calls to the local emergency number using any available and compatible network, even if not subscribed to a provider.
There is a massive interest by the public and mobile phone GPS jammers use has increased over time even though they are illegal. In this technological world, the need for such devices cannot be ignored.
Cell phone signal jammers interfere with emergency calls in emergencies. Contrary to popular belief, these signal jammers do not block emergency calls, thanks to a feature built into most smartphones that allows them to make emergency calls even without a SIM card.
- This feature is designed as a safety measure to ensure that individuals can make calls to emergency services, such as 911 in the United States, 999 in the United Kingdom, or 112 in Europe, regardless of network connectivity.
- This is standard international practice and is enforced by national laws.
- In the United States, for example, there are regulations that require mobile phones to be able to make emergency calls even when there is no service.
When you try to make an emergency call, your phone will look for any available and compatible network, bypassing restrictions such as roaming settings or unregistered. Emergency calls take precedence over other network restrictions, ensuring that you can connect to emergency services regardless of your network provider.
The rationale behind this design is simple: if you have a mobile phone, emergency services must be able to answer your call and forward it to the appropriate call center, regardless of your subscription status with your network provider.
