SoyMomo, among its security features, has a filter to block calls from unknown numbers. Any number not added in the phone guide can not call your SoyMomo. Only the numbers added to the phone guide of your SoyMomo will be able to communicate. If a number is not in the phone guide, calling will sound as if it was turned off, not being able to go through.
If calling your SoyMomo it sounds like it is turned off, probably there is a mistake with your contact number in the phone guide or that the phone number associated to your SoyMomo has not been added correctly in your contacts.
