as soon as I landed I put the card in and it worked. US and Mexico were both fine for internet. Didn't really call anyone :)
I was surprised and would use this product again!
I was a little scared to just pop in another sim card and expect it to work , but it actually did!
Meanwhile, my sister had to pay $90 for a sim card at the airport because she didn’t order one before. I definitely recommend!
