A method for verifying location information of a terminal equipped with a UICC card, connected to a cellular telecommunications network and located in a current cell, said terminal storing in the UICC card an identifier of the current cell and at least one identifier of a previous cell in which the terminal was previously located. This method comprises the following steps, implemented by a processing server connected to the network: receiving said identifiers coming from the terminal via the communication network; determining first location information using the identifier of the current cell; estimating second location information using the identifier of at least one previous cell; detecting a location error if the two items of location information correspond to different geographical positions according to a defined criterion.
