Hello, I am traveling to Brazil in a few months and it will be my second visit. the first trip went really well but I was unable to use my phone even though I made arrangements for a local sim card. I was never able to figure out the problem, so i thought this time I might try using an eSim service. I am traveling from USA to brazil for a few weeks, would you be able to give me any advice or suggestions? which service to use or anything to be careful of?
