This information is not correct. Starting with the iPad Air and mini 2 there is only one hardware variant of the iPad used by all carriers in the US. In the case of the iPad mini 2 it is model A1490. A1491 is intended for use outside North America.
Also, Sprint does not use bands 38-40 (you are probably thinking of band 41, which at this point is not that widely deployed).
i was a little off. but he did ask specifically what the difference between a a1490 and a a1491 was.
A1491: 1, 2, 3, 5, 7, 8, 18, 19, 20 and TD-LTE 38, 39, 40
A1490: 1, 2, 3, 4, 5, 7, 8, 13, 17, 18, 19, 20, 25, 26
sprint uses 25, 26 and 41 ( 41 is correct )
how am i supposed to know what country the OP lives in. he didn't say i lived in north america

I picked up A1490

Will it run bad on Tmo network?
the only bad thing about iPad air, iPad air 2, iPad mini 2 iPad mini 3, iPhone 5, 5c,5s,6 and 6+ is they all lack channel 12. channel 12 is a low frequency channel t-mobile is rolling out in rural areas and other areas in the united states that offers better coverage outdoors and better coverage in buildings .
but its rolling out slowly but gradually.
here is a channel 12 map

other then that t-mo works on channel 2 and 4 so you are fine
i would like to take the opputunity to troll about tmo
1. if you sub scribe to the cellular plan ($20 for 1 gb minimum ) you get music freedom, just like if you had a phone plan
2. tmo just started offering rolling data , where everyone gets 10 gb of roll over data and any data you do not use gets rolled over into next month.
however. right now if you activate the sim card on the iPad and you are a prepaid customer, you do not get data stash at this time. prepaid customers will get data stash soon
if you want data stash TODAY you need to walk into a t-mobile store ( or website) and sign up for a postpaid plan
prepaid and postpaid both get feee music streaming.
i talked to tmo and reserached it, and decided to cancel my data plan and let the data expire at the end of the month, ( i turned off auto pay) and then switch to post paid later this month
end of troll
