Bests & Worsts Reviews from Amazon

I got this Sim card as a freebie from Amazon (along with the purchase of an unlocked phone) and to activate the Sim, I was asked to give my credit card details and the Customer Service rep wasn't very convincing about whether I'd get $20 worth of free minutes. And, when I asked if the Sim would let me know I've used the entire $20 worth, she said NO. I'd be billed on my credit card for extra charges, as long as I use the Sim card. For people traveling abroad, I'd suggest going with a SIM card from local providers. For calls made from India to US, MOBAL is charging $3.95 per minute whereas, local carriers allow international call for Rs. 10 per minute, which is approximately equivalent to a quarter (25 cents in US).
