I got an email from Waleed saying that the current offer from STC (any call longer than 5 minutes will be free, so they will only charge you the first 5 minutes) is a big lie! Apparently most calls cannot make it to the 10th minute before it gets disconnected! Whether it is deliberate or just a network overload is not known.
Do you have similar problems with this “offer”? Do you notice sudden disconnections after the 5th minute? Feel free to post a comment bellow!
