To the OP: You can get truly unlimited data with VIVA but it will be EDGE speed, 256 kbps at best. Orange or Claro you can get 3G but your usage will be limited to 3-5 GB depending on the plan (per month). Use wifi if you need. I have a Galaxy S4 and I used only less than 100 MB data this past month (I have 5GB limit), rest is via WIFI. Connect to wifi wherever you can and don't be shy to ask for access or password.
