For everyone wanting to know about Clay Sim Cards please never use any services that are offered by them. I bought their rental free sim card for Dubai and on face value it seemed very affordable to call back India. But true story actually revealed when i got my bill, i was charged 75 dirhams as rental along with a 8k rs for a period of 5 days. This is clearly no where being close to affordable and now am stuck playing email games for refunds which doesn’t seem to happen anytime soon.
