I only see disadvantages in taking insuarence in India. For many students paying the bill upfront is not at all possible. Then comes the troubles of claiming it. Apart from this informing the insuarence company in advance is not possible when you have first to see a doctor to confirm your illness. Who will pay the outpatient visits. On the other hand an insuarence from the coutry of visit enable the students to visit the physician or specialist doctor without being paid and pay less hospitalisation benefits. Here in Germany many had to take in the end an insuarence from here.
