You can use your roam sim for call, text and data basta may load but I think not for freenet, For local Network lang po ang mga freenet natin. Once na nasa ibang country ka na hindi mo na magagamit as freenet. dahil I think hindi na kasi direct from clients to local Network. dadaan na sa isang Global Network na kapartner or may agreement sa ating Local Network kapag sa ibang Country.
Example:
Philippines
Clients --->> Local Network (Globe or Smart)
Other Country
Clients--->> Global Network Host (Vodafone) --->> Local Network (Smart or Globe)
