Will emergency contacts in bicycle sharing receive text messages?

The bike sharing emergency contact will receive a text message.

As well as the contact person, we will receive this short message or phone call when the mobile phone can't get through and then we can't get in touch, because we are filling out this resume. Anyway, as long as we fill in this emergency contact person, our mobile phone will show that we can't get through, and then when we can't find it, then this emergency contact person will receive the phone call.
