Hi,
I'll be traveling to 2 diff coutries next week and aim to use my Existing Phone number while there for business reasons.
Now, the first country, found it will be cheapest with Telstra 10$ day pack.
2nd Country (USA), cheapest if I go with Vodafone 5$ day roaming.
Now, is it possible to activate and transfer my number from telstra to Voda before I board the second flight? or do activations/transfer need the sim to be in Australia?
Cheers.
As long as you can do all the steps over the Internet and any SMSes are sent during the process you have to take action on can be received.
