We recommend that both residential and business subscribers issue a request to their mobile network operators regarding information on roaming charges before entering the United Kingdom or leaving the UK for Hungary, as the roaming charges may change, taking into account that regulated roaming and international charges will not apply to the UK, so the regulated charges are not applicable.
Hungarian mobile network operators will notify their subscribers on applicable roaming charges in instant messages upon entering the United Kingdom, when they are within the range of network of another service provider.
