There is a service called PAYD which allows you to make purchases through your sim card, similar to the Vodacom Express Recharge. So when I enter my number on the website i wait for a accept menu to pop up shows up as the toolkit with the amount im about to purcahse with on my vodacom simcard, after clicking ok i wait a few seconds then a white small menu screen pops up for a few seconds and just closing preventing me from completeing my transaction. This is specifically on my Hauwei P8 Lite but on other cellphones with the exact same sim card this purchase through sim toolkit or whatever its called works flawllessly. I'm frustrated cause i would like to purchase and Item off of takealot.com and my phone is preventing me from doing so.
Could anyone tell me how i can fix or overcome this issue?
