A Mobifone sim was left for me when I arrived at the hotel in HCMC and I now need to register it, however I keep getting told it has to be done between 8-5 and Mon-Fri which is no good because that's when I'm at work. I've just tried having a blast online but it says this portlet is unavailable? It then says you can on the app because it picks up your number automatically but that didn't work.
Any ideas?
