No longer the best price I have been purchasing my T-Mobile pre-paid SIM card top up from Callingmart for the past several years. I started buying from them because they had the most competitive price. But it is no longer the case. Since last year, I have to pay the full face value plus $2 fee (required by T-Mobile according to Callingmart). I can get it from any other online seller for the same price and even from T-Mobile website (have to pay sales tax but not the $2 fee) with he same convenience of online shopping. I probably can go to one of those small Mom&Pop telephone store and get it with a discount to face value (+ sales tax) if I look hard enough.

Stay away from this company - Broken Website Stay away from this company, Callingmert. Their website is broken all the time. They will take your money, put a hold on it, then they will send you an email stating that your card is out of stock and will take a week to release a hold on your money. This happened to me 3-4 times already. Their website is broken 9.8 times out of 10.

Their mistake, At my expense I ordered 1000 pre-paid minutes for my cell phone. I used a coupon and all my member points. Some where during my checkout, the system changed my order to 900 minutes. Since the minutes are cheaper per minute if you buy 1000 minutes. I am paying more per minute than I should. It was their system that glitched and made the error. I could not catch the error since I could not see the change happening since my coupon and member points change the price. Callingmart chose to not help me at all and put the blame on me. This is really poor customer service. Now that I have no more member points anymore, I have no reason to ever work with them again.

1st time worked 2nd time order held Order was held up. Had to use tmobile site instead. Probably will not use again
