I purchased a 15 G data SIM card from Tune at the aiport. When I inserted it, I couldn't use it because I needed to unlock my phone I tried several methods as per the AT&T website, but I still can't unlock it. I can't even get to AT&T customer support. I keep getting a message, ' we are having trouble with this service.
In the meat time, I am using my local home phone number for Grab. But I ran into a problem yesterday when trying to get Grab back to my hotel from Batu Caves. I had no internet connection. Plus, I am concerned about data charges when using my local cell phone number in Malaysia.
Fortunately I found a Cafe that had a booth where I paid 3 ringits for 30 minutes of wifi.
I booked the Grab.
My question is, "can I get a refund for this SIM card? Is there another way to unlock my phone?
I've unlocked my phone seamlessly and quickly in Africa. Idk why I am having such problems here.
