If your local T-mobile has a strong 4G signal covered, we recommend one T-mobile (prepaid data-only SIM card, much cheaper, 2GB/$10 per month) and virtual US mobile(white sim card) or AT&T(3 in 1 SIM card).
And we have tested the virtual sim card like cricket and Freedompop(based on AT&T) which can work with our camera properly.
You could refer to the below to choose the most suitable SIM card for the camera.
You could buy these SIM cards in the link below and activate these sim cards on their website conveniently.
