PingSMS is often also called Stealth SMS or Silent SMS or Type 0 SMS and lets you determine if the recipient phone is switched on / booked into the network or not. If it is not you will receive a notification as soon as it is available again.NOTE: I have a 24h refund policy extending the usual 15 minutes from Google. If you cant get to work send me an email. I will try to help you. If we cannot get it running on your device I will refund your money!
This is a GSM only App. It will not work on CDMA Networks.
You may already have heard of this kind of messages. Officials (like feds or other agencies) use this kind of message in conjunction with the service provider to locate you (or your device). HushSMS uses it in another manner, since we don’t have access to the provider network. HushSMS uses this message to determine if the receipients device is currently booked into the network and as such the receipient should be available or not. As per standard this message muste be received and acknowledged by any cell phone without notifying the receipient. Thus this message is also call “silent sms”. I have heard (but never personally seen) that some providers transform this message automatically to an empty default message. Thus, if this is true, the senders number is shown, but no one will guess why an empty message was sent.
It works on devices where the sendRawPdu API Method is present which is only on HTC Devices with stock ROM and Sense UI.It will also work on Android >= 4.0 devices which have the Xposed Framework installed. If that is the case for your device please download and install the Xposed Helper Module from here: https://www.silentservices.de/android-hushsms-xposed-helper-module/The current version of the Xposed Module is 1.7.8 which is the minimum version required by Ping SMS to work properly. If you have a HTC Smartphone with Sense UI you will not need the Xposed Module!
