I suggest u cancel that UK account via email, and/or sign up a new Spanish Boon account.

This is because the UK account can only topup via Faster Payment, while Spanish one can topup via bank transfer or telegraphic transfer (TT).

I sign up on iPhone, after download that Boon. app, then **set Region to Spain in iPhone setting first** (you can switch back later),
then fill in your info...
In order to use the Boon. prepaid Mastercard via Apple Pay worldwide,
you'll need to upgrade to Boon. Plus account by submitting your photo, passport frontpage, your ultility bill or bank statement (no PDF),
or your driving licence (front and back) to proof your identity and address.

Yes, you don't need an Europe address or phone number to sign up, they just want to make sure your info is true.

You can only top up via bank transfer or telegraphic transfer (TT), credit card issued outside EU cannot.
Once you get signed up, you'll get a virtual prepaid Mastercard, and a Germany based bank account number.
For bank transfer via local bank is expensive, RM10 for each transfer via Maybank TT, and RM25 with RHB bank.
So I use Skrill to do bank transfer. The rate is OK. For Skrill, you'll need to sign up an account and get verified (similar to above steps).
Skrill can topup with your debit or credit card, and it takes about one business day to process.
Normally when I topup at 3pm (8am in Europe), and the fund would be received at 9pm, or latest by 3pm the next day.

I feel cool when I use Apple Pay here in Malaysia haha, and I can also use it as Transit Link while riding MRT in Singapore.

Thanks for the head up n guide, had tried and successfully verified as boon plus.
I think this card is quite good card for overseas (by connected it to applepay & googlepay) & do some overseas online transaction.
I think it somehow same as bigpay, did not charge FX fees like other bank credit card do.

Found their new app when go to register yesterday on their website. Boon.planet https://www.beboon.com/de/en/boon-planet
With Germany bank account & Debit Card, deposit to the bank account have interest earned.
I just get it verified. Will try to figure it out, the card also can save in ApplePay.

Ya had amended as above. Cannot ya for boon plus, only bank transfer.
