Right now the urgency to get a dollar master card will reduce considering this upward review of dollar transactions on naira master card. This has been a battle ever since when Nigerian banks set limits to naira Master cards usage for foreign transaction.
The good news is that you can now use your Naira Master Card to shop on foreign sites like AliExpress, Gearbest etc with monthly limits of $1000. At-least this will save you the hassle of opening a dollar accounts or using barter virtual cards.
GTB Naira Master Card Limit for Foreign Transaction now $1000

As at yesterday, GTB charges N380 per dollar which is still very much on the high side and I’m not comfortable with that. If you already have a dollar account, no need to use your naira master card, just buy dollars from Bureau de’change and initiate your transaction; but if you don’t, then you can make use of your Naira Master card.

The bad news is that to make withdrawals with your naira master card abroad, you'll be charge N1000 instead of N420; and you can only withdrawal $300 daily.
