I've recently entered the world of porting between discounted starter SIM packs. In fact, I just took advantage of the latetst $15 for the $30 Telstra starter pack at Woolies (bought 5 of them). I'm currently on Amaysim PAYG.
My question relates to porting while overseas. I expect to be overseas when it's time for me to port, which I can't see as a problem since porting is now a fully automated system online via various Telco/reseller activation portals. But if I do so while overseas, does this pose a problem? Since I may be roaming on a local provider's network, does this impact the process?
And finally, I've read in other threads that it seems to be smoother and much faster to port from different major carriers, as opposed to within the same major carrier. In that case, to activate each of my Telstra prepaid SIMs at expiry, should I just get any Optus/Voda $2 prepaid SIM? Does everyone else just buy them from a supermarket or dept store?
I suspect porting won't work while overseas. For example, you are on voda n roaming in US and you request to port to Telstra. But telstra Sim is not on roaming as yet since it's not activated. So porting will fail as your overseas network won't identify telstra Sim.
