I doubt of ever using a clay international sim again for any of my travels. Their services are not at all trustworthy. My phone stopped working within 3 days into my trip and u was in Sri Lanka. Desperate calls to the service ppl didn't do much either, all they kept assuring was that they would fix it but that fix never happened. Ultimately I stopped using the SIM card cz it was useless to me. It would have been better had I used my number than pay for a stupid service which didn't work in the end.
