+1. Create a consumer account: https://www.anveo.com/consumer/default.asp. You will need to enter personnal information aobut your main residence but this is only for billign and legal purposes (it won't impact your ability to purchase a number from a country).
+2. Once on the main screen, click on `Add funds` or navigate to https://www.anveo.com/addmoneyother.asp. Funds take some time to be process (took ~2h in my case).

+3. When the funds are in, click on `Phones Numbers -> Order a New Phone Number` and select `Geographic` or `Mobile`. be sure to pick a phone number in a country where `SMS` are supported.

+
+4. Once you click on `Order phone numbers selected`, you must choose a plan. If this is only going to be used for SMS, I suggest going for the cheapest `per minute` plan.
