The question at issue is whether the service of GSM Roaming should be declared. The relevant criterion is whether declaration would promote the long term interests of end-users. To examine this issue, this note focuses on two questions.
The first is whether there is evidence that current competition in the supply of mobile services is in some respect inadequate – so that there is scope for regulatory intervention to improve on matters.
The second is whether – even were current competition inadequate – mandatory roaming would be likely to yield better outcomes than would otherwise prevail.
