I heard that sending text messages via Fetion mobile phone only requires data. Isn’t that almost free?

Hello, it is a fee. If you open a monthly Internet subscription, it will cost money. However, if you only open GPRR and do not guarantee Internet traffic, then when you use Fetion, the money will be deducted a lot. It may cost dozens in just a few minutes, but that's not a lot, so you still need to open at least 10M of Internet traffic. That way you won't be charged for it, but be careful not to overuse it.
