I have been seeing people recommending to buy sim cards from ebay, but i am wondering if we can ship them cards to wherever we want and use it for receiving text? If not, in the case of fb, can we use a different number for re-verify? Which means I can just buy from any "verify" service sellers and it will work? Reason: My country has limits on number of sim each person can hold at any one time, and the cost to make it valid for 1 year is more expensive than plans out there. I am finding for ways that can do this reasonably cheap and at mass scale at the same time.
