How to buy USDT using Wirex?

Could you please elaborate on the process of purchasing USDT using Wirex? I'm particularly interested in knowing the steps involved, from setting up an account to actually making the purchase. Additionally, are there any fees associated with this transaction, and if so, how are they calculated? Also, what are the security measures in place to ensure the safety of my funds and personal information during the process? Lastly, is there a minimum or maximum amount that I can purchase, and are there any restrictions or limitations that I should be aware of? Thank you for your assistance.
