Your iPhone is capable of performing multiple different tasks, from the original of a phone to others that have been incorporated much later, such as taking photos, looking for a restaurant or writing on social networks. They are not just phones anymore, now they are small computers capable of anything.
However, there is something that takes us back to the past, when phones had an eternal battery, the only game was the snake and SMS were the top in terms of communication. We go back to the late 90s, with the explosion of mobile telephony for the general public.
And maybe something remained of that, those known as USSD codesof Unstructured Supplementary Service Data, since at that time there were no applications that executed such commands. That is why we have proposed to bring together a good number of them and you can use on more than one occasion. These types of codes work very simply, you just have to go to the telephone dialing screen and type the sequence indicated. Get on the time machine and go through the 12 essential USSD codes for your iPhone with us.
