I am going for trip to Vietnam, Singapore in few weeks.
Just seeing if anybody knows of the best pre paid travel sim.
I was looking at TravelSim but they cost $50 for starter pack with $5 credit. Which is too expensive as its $45 for the sim itself.
Any recommendation or past experiences?
Buy a sim card in Vietnam. It'll cost you about $7 or $8 and give you a number and plenty of credit for local calls. I had credit left at the end of 3 weeks. I'm not sure how much it will cost you to make calls back to Australia if that's what you want to do, but certainly no more than international oaming. Plus you can do SMS to Aus very cheaply.
