Just awful service – I had taken a pre paid sim card from Clay International sims and it was just so awful. The first 2 days were fine but then call drops became a regular feature and everytime i would switch on my data , it would ask me to recharge again despite the fact that there was already a data pack activated on my number. I wished i had used my Mumbai number only that would have been more convenient really. Wouldn’t recommend using Clay Sims to anay traveller.
