Indian ban on Bangladesh SIM

We, who do honest business, know only too well that our good neighbour India is incapable of fairplay with regard to Bangladesh ---- in all respects. While we stick our necks out to please them and show their commercially important people 'jamai ador', we Bangladeshis get only stepmotherly treatment in return, whenever we interact with our Indian friends.
Indians seem to have an 'attitude' problem vis-à-vis the people of this small country with a very big heart. So it is no surprise that they should slap a ban on the use of Bangladesh SIMs in the Indo-Bangla border areas on the pretext that it is a threat to their security ! Isn't it laughable ?
