Kickback gone for voice lines but not my tablet

I lost all my kickbacks like everyone else, but I didn't notice until I got a text about the usage on my tablet line that I had gone over the 2GB for the month. I had just assumed that they were all gone and didn't bother checking the tablet. I had it in my iPad for the longest time but rarely used it to take advantage of the free $10 credit most months. I recently moved it to my GliNet GL-E5800NA travel router, and I'm traveling this week. If they're going to take away the benefits, I might as well use as much data as I can, whenever I can. For those interested, it is an eSIM and was easily transferred to the travel router. So far I'm getting full 5G speeds. Posted about that here .
