I regularly use prepaid phone cards for making phone calls. But what annoys me the most is the sudden expiry of these cards without any prior notification. I have been unable to make important phone calls at times and been in trouble due to this. I want a prepaid card with a long validity.

Switch to Talkloop. Talkoop has prepaid phone cards with some great features. With Talkloop cards, your account and PIN will expire 6 months from the day of the last successful call and then will be become disabled. However, the expiry date is automatically extended whenever you make calls or recharge. Log on to for more details.
