Can call forwarding be realized by SMS?

According to the information you provided, when the mobile phone is out of the answering range, busy, the battery is low or turned off, the phone can't be answered, or the mobile phone is not at hand, the call from others is automatically transferred to a temporary phone, mobile phone or voice mail. This situation is called call forwarding. Call forwarding does not transfer short messages, only incoming calls. For details, it is suggested to contact the Unicom customer service to which the number belongs.
