From Simplex FAQ:
Why my location is not supported?
We strive to support the purchase of crypto via credit cards in as many locations as possible across the world. However, our services are required to comply with the regulatory and other legal requirements of each location.
Therefore it is possible that based on your country, there are restrictions on the purchase of crypto and therefore the transaction cannot be approved.
This list of approved locations changes frequently and therefore we cannot provide a reliable, exhaustive list of all supported countries. However, we can share the following restrictions:
If you are from the United States, the following states are not supported at all: Georgia (GA), New Mexico (NM), Hawaii (HI), Washington (WA), Oregon (OR), Vermont (VT), Florida (FL), Alabama (AL).
New York (NY) and Connecticut (CT) are currently supported only for the purchase of BTC.
FATF high-risk countries are not supported. You can find the list of FATF high-risk countries here.
Please also know that the website/application/exchange that you are accessing Simplex’s service from might also not support your location based on it’s own business considerations.
Apart from the above, all countries should be supported (e.g. all European countries, Canada, Australia, Japan, Russia, etc) are supported.
Without contradicting this, please know that Simplex might not be able to support certain locations which otherwise are usually supported, for a short period of time due to other business considerations.
