I used all of my high speed data in my Verizon Plan and was switched into Safety Mode. According to the FAQs, Safety mode is supposed to be limited to 128Kbps. I assume this limit is supposed to apply to all of the time, because the FAQ does not mention "congestion" or "peek times".

So far I have not experienced any slowdowns. Pandora and Netflix stream fine. Speedtest shows 11.35Mbps on my iPhone SE. Since this is the first time I’ve been over, I wonder if this is a grace period or if this is just an bug in Verizon’s system.
