Hey, @whatamidoing.
Oh, man.
If there's anything that trumps spending Christmas Day with wireless tech support for nearly four hours, it's dealing with the visa office for five hours on Christmas Day.
I feel your pain, because immigration is a similar process that we went through to get my wife permanent residence status, then citizenship.
I hope it all worked out.
If not for the whole SIM card switcheroo, I think it would have been fine. The online process is really painless, and I don't need to contact the former carrier to close the account.
I just should have gone with my gut and changed SIM cards.
