What exactly are International Sim Cards
Let me explain in very simple terms. When you buy a sim card (locally in India), your sim card is functional only in your area (city/state). When you go out of your state, you end up paying roaming charges. Same applies for International Calls (roaming) as well.
But, how about you can buy a SIM Card in India itself and when you go abroad (to a say USA), you don't have to pay any roaming charges. This Sim Card can work anywhere in the world (terms and conditions apply : some countries**) and you don't have to worry about roaming and all. Also, these are prepaid cards, so you will get some talktime which you can use while you are abroad. Rest you can reimburse after you return. You can avail for post paid option as well.
