Wise and Revolut, can open both online.
Use your brothers address to open the accounts, don't tell them your're not living in the UK.
A pal of mine opened a Revolut account in the UK last week, using his family home address (his last UK adress) which they left 30+ years back.
Revolut have a very nice virtual Debit Card system, where you can make a new virtual card, for payments setting your own limits, or just for 1 purchase.
Wise are best for moving money to foreign countries.
