Hi there. Am on a My MBB Plus 10GB plan that came with a Samsung Galaxy Tab S4. Whether I use the Tab or a mobile phone to access the data (I have tried the SIM in multiple devices and none of them work) I cannot receive SMS. I understyand that voice calls and sending SMS is not included, but I was told that receiving SMS would be fine. All I want is to be able to get the activation messages for chat apps, like WhatsApp and Viber. How do I get this working? Thanks all.
