I don’t mind so much if the ID on file expires, but doing this every time I re-enter the country, as the regulations seem to be written, is going to get irritating fast!
They should really do something there that isn’t treating every resident foreigner as a tourist. Not sure how many foreigners living here have prepaid plans, but it’s worked pretty well for me so far and I don’t see much advantage to switching to postpaid (besides this silliness).
