Depends on the tablet and your carrier. Some have different sized SIM cards, and some carriers who use internal (CDMA like Verizon) cards.
I bought an iPad
Air 2 that has the T-mobile and AT&T card drawer. The SIM card ones have the barometer and GPS too. It works really well.
However, when you add a device with a card, watch out on your plan! I have T-mobile and I was on their pre-paid plan where I would put 6 months worth of credit (~$360) so I wouldn't get a monthly bill. I had about $200 still on credit with them when I added the iPad. What they do is change your plan enough to the point your pre-paid money is kept by them and they will not refund it nor credit it to your new plan. You lose it all! Also, the new plan may end up coming along with a lot of extra taxes and nonsense. Mine went from $60/mo exactly (Which was an easy $360 for six months pre-paid.), to $84.32/mo. with the iPad added on which they claim is only a $10/month additional fee, but they add so much taxes and stuff it's closer to $20. Not to mention them keeping any pre-paid plan monies you had with them too. Luckily I bought my S6 Edge (And prior phones too.) and plans from one of their stores and the manager is issuing me a few months of credit from their shop to re-coup corporate from keeping my pre-pay.
Aside, I tried to go the hotspot method to avoid the tablet SIM between the Samsung S6 Edge to a Samsung tablet, but the hotspot syncing slowed down the data/video stream far too much. Android and DJI Go is just too laggy for me with the Samsung bloatware. The Apple seems to run a lot cleaner, imho, but it costs in SIM world as well as initial price both.
Also, check the website Rootmetrics (
RootMetrics Coverage Map ) and their coverage map for cellular companies. Seems Verizon is the best for data overall for rural/remote areas if you want to fly out there, and if your city has banned drones with some ordinance or you are in a NFZ area.
