Count With a radio to batteries It is essential to stay communicated in emergency situations, as demonstrated by the total blackout suffered by Spain in April 2025, after running out of electricity supply or telephone connections - FIJA and Mobile - and Internet the entire national territory for more than 12 hours.
At a time like that, in any emergency situation in which telecommunications fail, having an FM to batteries is the only thing that can keep you informed.
Until a few years ago, it was common for a transistor to be in every house. However, the popularization of mobile telephony and the Internet has left those forgotten devices in a drawer - in the best case, when not in the garbage - and have been replaced by digital receptors and mobile applications of the Internet radio that allow you to listen to stations around the world.
But of course, these devices and applications need Internet connection to function, which prevents use in emergency situations such as described. However, there are mobile phones that include an FM radio receiver. They are, above all, models manufactured years ago and, mainly, with mid -range and low.
The manufacturers have discarded this component in the manufacture of the new phones, especially in the high -end, to achieve a thinner and thinner design, but some mobile phones manufactured in the early 2010s do have it, as well as some of the most basic models of Chinese brands of mobile phones such as Xiaomi, Oppo or Realme.
Do you have my FM radio mobile?
To know if your mobile phone includes an FM radio that you can listen to without internet connection, the most direct thing is to consult on the official website of the manufacturer the specifications of that model in question. That would be the most reliable.
Another possibility is to access your mobile phone search engine and put "FM radio" (or ask the voice assistant directly). This will generate a search and offer results, what happens is that other apps that you had installed and that allow listening to the radio online could also appear.
To check if your mobile has an FM radio chip and can receive the signals emitted by the traditional broadcasting stations, you must connect cable headphones to your mobile phone (as you see, another somewhat expired technology). This is necessary because they will do an antenna to receive the signals, acting as a receiving element. Without them, nothing would be heard.
Try now, for example, to listen to the radio activating the "plane mode" of your mobile phone. So you will not have an Internet connection, if with that app and the help of some stations tuned headphones, then your mobile phone incorporates the FM radio chip to listen to it offline.
