SMS Bell (No Ads) (com.jrobertson.smsbellpro) on Google Play
Use this bell to call somebody when you want them! It makes a pleasant ringing sound, as you might find on a shop or hotel desk. In case they are not within earshot, you can switch on the SMS function and it will also send them a text message asking them to come to you.Using the contacts picker, select a contact and number and then simply enter your message.This is the same as the free version but with no adverts, and as a bonus you can have that warm feeling you get from supporting a small app developer
