Roaming did not work in 4 of the countries that I was in the past 8 days, all countries are on the list of supported for roaming. Mint makes a statement that they have roaming and that is why I bought. I added Roaming balance. I did turn the phone off in US and only turned it back on in the new country but to no avail. Chat was automated and said someone would be in touch but nobody was. This is a useless services to me at this point, how to get refunded since this is false advertisement?
