People spotted a spelling error in the Government's mobile phone alert that was sent out on Sunday afternoon (April 23).
The new emergency alert system, which will be used to warn people about dangerous situations, such as floods or wildfires, was tested out nationwide on all mobile phones that are compatible with 4G and 5G.
However people living in Wales spotted that the Welsh-written version of the alert message contained a spelling error and did not directly translate to the same in English.
