I, still, have this on our iPad mini (Sprint variant w. 4G/LTE) for backup - as Project Fi's data-sim only is great for global travel vs. T-Mo's domestic only option. 200 MB would probably be adequate for 2 or 3 days of moderate use, maybe a little more depending on one's setup, when out of reach of a good WiFi signal.
Did a factory reset on the iPad mini and happy to report that the IMEI was recognized and settings restored, and is still working on the same iPad mini - despite using my alternate Apple ID to configure it for different usage (purchased Apps shared as Family)
