My boss and i were travelling to Malaysia for a Business conference and on his friend’s recommendation we used Clay sim cards for the same. Cant say for him, but for me it was by far the worst services that i have ever used!!! Poor network throughout the trip, like barely a signal also. I am so glad that i had taken my Indian number emergency as a backup which actually turned out to be the one that i used., cz the clay sim card just didnt work at all. Clay Sim Cards are a total waste of money. Literally !!
