Which commission-free card options are available to UK residents who want to travel abroad? [closed]

I am traveling to Bangalore from Edinburgh via Dublin and Abu Dabhi.

The thing is I have got a good layover time in both Dublin and Abu Dabhi and so I'm looking to do some shopping over there.

To be honest, Monzo sounds a pretty good deal, like one can withdraw money, do swiping without any extra charge in almost any country.

But I'm still on the waiting list for Monzo.

When I searched on internet, there are so many travel cards like Thomas Cook etc, but I could find none like Monzo so far.

I thought of buying local tickets but again it's a bit hassle as there are some limits to money that we can carry like that.

Can anybody suggest me the best travel card with pretty good deals and trust worthiness?

Update

Basically I am looking for a travel card with below options

A card that charges less or doesn't charge any fee for transactions and money withdrawals.
A card that supports many currencies
A card that works with many ATMs

Money Saving Expert has a good run down of commission-free cards available in the UK.

In particular,

all meet your criteria.

They charge no fee at all for transactions and money withdrawals and use the VI~SA or Mastercard wholesale exchange rate. (They are credit cards, so with the exception of the Barclaycard, they will charge interest from the moment of withdrawal, so it is worth paying them off immediately rather than waiting for the monthly bill. If you do this they are free.)
They support 'all' currencies
They will be accepted widely as they are VISA or Mastercard.
