Heading to US tomorrow and want to set up data on my phone. Apparently ESIMs are very easy to use but I am very tech inept! In the past I have taken an old physical phone and inserted a physical SIM at the foreign airport. Data mainly being used for booking Ubers and Google maps. Will only be in the US for 5 days. What do I need to do and what is the best company to use? Thanks for enlightening me!
