5.

National regulatory authorities may intervene on their own initiative in order to ensure compliance with this Regulation. In particular, they shall, where necessary, make use of the powers under Article 5 of the Access Directive to ensure adequate access and interconnection in order to guarantee the end-to-end connectivity and interoperability of roaming services, for example where customers are unable to exchange regulated roaming SMS messages with customers of a terrestrial public mobile communications network in another Member State as a result of the absence of an agreement enabling the delivery of those messages.
