They call you and then charge you

Hi tech tricks?

You can not be charged for any incoming phone call, except when you confirm that you will accept the incoming call costs. This happens when you’re receiving a call via direct reverse charge (also known as collect call) on your phone. But this is always announced, and you have to possibility to decline that call: no charges.

Most likely people who are adamant stating this, confuse on their phone bill “call charges” and “SMS charges”.
