Hi, you solved it for a while. I'm starting to think it's a carrier issue. The carrier (DIGI) is new to my country, so I think it still has some issues.
The carrier in question takes a while to register with the network.
For example, when I use the other card, the internet connection is instantaneous. When I use the DIGI card, it takes about 10 minutes to connect. There's a network, but data is slow. I think it's a carrier issue.
