When I received this card, I followed the instructions to activate it, then for some reason I could only receive calls, but I could not make any calls, I contacted Telcel customer service and they told me that this card only has 20 pesos of balance and that is frozen for that reason I could not make calls, when I bought it supposedly it was charged for unlimited calls and sms service for 30 days, very upset, today I return it, I recommend NOT buying this item because it is a fraud.
