So my free trial with AT&T ended and I added the car's phone number to my existing AT&T account. All was well, the wifi continued to work as intended. Then all of a sudden it no longer works. I thought it was because we drove through an area with poor cell coverage but once it dropped I have been unable to get it back on. It works for carplay etc., but we are unable to access the internet through it. Any suggestions? I was thinking I should call BMW genius or even AT&T but thought I would ask here first to see if anyone else ever experienced this....

Thanks,
