Post prices
Prices are posted on the OP. Please refer to it.
If you want a new type flagship spec phone, like the specs of OnePlus 5/S8 etc. Then the cost is basically doubled. (Between $800-$950)
If you want a regular decent spec phone OR mobile hotspot, it is included in the OP post pricing. No additional charge.
How can you guarantee that it will work forever? We can easily say that it can work forever but there must be a solid proof and a guarantor so that many peolpe will believe that is legit. If you can give us that im sure some of us might avail.
There is no "guarantee it will work forever". The longevity of this is
INDEFINITE. (Please think of this logically.....think of cassette tape to cds to digital formats, everything is eventually phased out. LTE is not a technology that will be here forever, just like 3G was phased out by LTE, LTE will be phased out like anything else. 4.5g/LTE+ is already here 5g is already being tested.
Nothing lasts forever. Literally. If you let water drip on anything for an indefinite period of time, the only thing that will last is the water.
With that said.....the only basic semi-guarantee I can give is this:
As long as Sprint has a LTE network, this will work.Please refer to my previous post regarding the nomenclature:
