Just learned of shoppre which apparently allows people outside of India to buy products off flipkart and some other Indian retailers. Also learned that Samsung has released an Indian specific line of Galaxy phones (Galaxy F series) that are a fraction of the price (as in ~$180 for imo really solid specs), but appear to have just as good specs. Only issue I've been seeing is that some with stickers that say "India sim only" require an Indian sim card to be inside of it for at least 10 minutes, then any sim can be used afterwards. Anyone know of this or any other potential issues should someone outside of India purchase one of these Galaxies?
