Hi gordon mackie,
This is a good question and I can understand why you want to monitor your usage when overseas.
I’m honestly not sure why the data counter is not recording all of your usage (or showing it all) however the data counter on VMC is not reliable and this is something we will always advise people of. The best way to monitor your usage is via online billing. If you’ve not yet signed up, I seriously recommend it as there are many other things you can do through My Account such as managing your price plan, upgrading or adding or removing bars.
Unbilled usage on here can be up to 72 hours behind though and with roaming charges, this can be up to 30 days. This is the same for us when looking at your unbilled usage on your account as it’s the normal delay in the network.
Try signing up for online billing thought as this will most probably be more up to date and certainly more reliable than the data counter.
All the best,
Jenny
