If you are up for lugging a few extra bits around in the utility belt. get the wifi hotspot from Altice. I have had one a few years now and it works fine and the price drops each time I am there. You can get an unlocked one from Amazon or likely anywhere although i got mine there.
Up to five devices, chicas can use it with you at the beach or the apartment. Yes there is wifi at home and most places we go, but its handy when in the car or out for a walk.
I go to the office and tell them how long i will be there, they open the back type in a few numbers on their phone and tell me its a go in five mins.
This time was three weeks so i asked for a month, I cant remember if they said 400 or 600 but it was only 2 gigs. Then he said I could get two weeks unlimited for $500 (Thank you!).
It was fast enough for facetime, Netflix, at one point i had 4 folks using it, never a speed issue but was a couple of dead zones up El Choco Rd.
