My bad its like 3am right now so take what i say with salt. So usually these mvnos offer coverage maps so use that tool to check out the area. As for what main options you have i think it would be:
metropcs: looks expensive and cant find an option for single lines, sucks for them
Boost: 15$ per month for 5gb, 25 for unlimited
Tello: pretty flexible with your plans options so pick and choose but 29$ for unlimited. sim card can only be purchased via their online store
us mobile: uses both verizon and tmobiles network 25$ for unlimited. sim card can only be purchased via their online store
Out of the options I would probably go with boost since it has the best chance at being found at a store and us mobile if you can have it delievered to an address within the states. Theres probably other smaller mvnos that uses tmobiles network so keep doing some resesrch
