So I work in Laos (previously covered as a Zone 1 destination) , and the revised definitions as well as the lack of any provision of Roaming Passes here means that this country becomes 200x more expensive for my data this month (based on attributing 50% of my contract rate to the previously allocated 4GB per month, 2 services with Roaming).
I am currently in Laos, and do not return to Australia until mid month.
1. On what date must I de-activate Mobile Data and "go dark" to avoid the standard roaming data charge of $1 per MB.
2. Is there any reason why I wouldn't cancel all 4 of my Optus mobile services in response to this blatant disregard for a reasonable expectation of continuity of services provided under a 24 month contract. As if "Zone 1 destinations may be subject to change" is adequate licence for this - so not impressed!
