Where have you successfully used the global SIM?

So far I have used it in
USA
Austria
Belgium
Denmark
Germany (a bit flaky)
Netherlands
Luxembourg

I have also tried and it didn't work in
Australia
Canada
Hong Kong
Japan
Taiwan

I will be trying these this year
Bulgaria
Ireland
Vietnam
possibly Mexico, Romania and France


Unfortunately, FreedomPop doesn't have access to cellular in Canada – free or paid. However, You can sign up for a calling plan (Free 100, or paid 300/1000 global minutes). These global minutes can be used to call Canada.

And if you use Wi-Fi, you will be able to use texting/calling in the country, but you must stay connected to Wi-Fi in order to do so.
