When using Wise, don't do any transfer of money directly from your UK bank account to your Thai bank account . Doing that, you're wasting time and money (Shitty exchange rate + transfer fees from your UK bank).
Instead, just open a £ wallet and a Thai Baht wallet on your Wise account (easy process that takes only seconds).
Then, transfer the money needed from your UK bank to your £ wallet on wise. Your transfer will be fast (minutes sometimes) and FREE (cause Wise uses his UK branch to do it, so it's a local transaction for them).
Then, on your Wise account and every time the exchange rate is at your advantage,, you convert money from your £ wallet to your Thai Baht wallet and store there as much Thai Baht as you want.
From now on and when you need to transfer some Thai Baht to your Thai bank account, you use your Wise Thai baht wallet to do so. The transfer will be fast (minutes) and at a flat rate (30,89 Thb) regardless of the amount sent.
By doing all that, you save on time, money, exchange fees and headaches.
