I have been noticing increases on my monthly bill lately and called in to verify. The agent told me the extra charge is due to an international call. But guess what: I have been calling my country for years using WhatsApp Video Call and I have never been charged, since I have unlimited data. When I google the question I realize I’m not the only one who has this problem with T-Mobile. On my first call to the billing department the agent told me that international phone calls made through WhatsApp can be charged; she issued a one time courtesy refund to my account though. Then I spoke to a second agent and then a third agent, who both blamed WhatsApp for the issue. Here is what What’sApp says on google about this known issue:
“WhatsApp uses your phone's cellular connection or Wi-Fi network to send and receive messages and calls to your family and friends. As long as you haven't exceeded your mobile data allowance or you're connected to a free Wi-Fi network, your mobile provider shouldn't charge you for messaging or calling over WhatsApp”
I I’ve been with TMobile for about 15 years, but this issue made me consider taking my business elsewhere, since I video call Brazil everyday using What’sApp. I was offered to have put a block on international calls on my account what I will not do since I must be able to call abroad in case of an emergency. So, in other words they may keep charging me and keep blaming WhatsApp for that. Thanks God they are not the only cellular company over there!
