Hello,
We have just recently released a cool new app Service Bell:
★★★ Introducing Service Bell - No Service Bell available at the reception desk? This service bell will get you the necessary attention you need and FAST★★★
- Link to Google Play-- https://play.google.com/store/apps/details?id=com.servicebellapp&hl=en
It will be free for a limited time so I recommend you download the app while it lasts.
Enjoy!!
