Ok, I've pretty much read through the whole thread and am still unsure about what I should do! Would love some advice!
I have $5 data roaming option with Vodafone. Which allows me to access my included data, calls and text with my current plan - 70GB per month.
I am travelling to the USA in August - I will require 18 days of roaming - so that's $90AUD but I will not have to do anything (anyone with experience of Vodafone in the USA, would love to hear from you!) and I will have plenty of data for using google maps, whatsapp, social media etc. I'm not expecting any phone calls (except the spam calls that seem to be prevalent now, which I wont be answering) my family will contact via whatsapp. However I may need to receive the occassional SMS for security (bank, etc).
Alternatively looking at esim, Airolo for example is $26USD (approx $39AUD) for 10GB. I will be using GoogleMap live directions ALOT, so I wonder if 10GB will be sufficient for 18 days plus the hassle of getting the settings right on my iphone?
Thank you!
