Same answer applies from when you asked about Costa Rica and Belize a few months back: there is no international roaming on Cricket, excuse Mexico on their $50+ plans.
Freedom Pop doesn't roam either, excuse their 3UK-based "global GSM" data SIM card. As for where that SIM can roam? It's currently only the United States, United Kingdom, France, Germany, Italy, Spain, Switzerland, Austria, Netherlands, Belgium, Luxembourg, Sweden, Finland, Norway, Denmark, Ireland, Portugal, Greece, Poland, Hungary, Slovakia, Croatia, Romania, Bulgaria and Czech Republic. They're claiming
parts of Latin America by end of the year, and by Latin America they only mean Mexico and Brazil, but who knows...
A
KnowRoaming sticker is your best option for light international travel usage these days (especially when using non-postpaid service with no international roaming options), and it can forward your incoming calls from Cricket to your KnowRoaming account if you remember to switch over before leaving the country.
