In Galaxy S4, you may not be able to send Premium SMS or shall we say,
it cannot send SMS to short numbered services like checking balance by SMS ,
replying to promotional SMS, or activation of Bank Cards,and many others.
(ex. 1233, 9947, 2626)
To fix the issue, please find the solution below.
Follow the path below:
Settings->More->Application Manager->All tab->Messaging
Scroll down and check under Permission->Send Premium SMS. You may find "Never Allow" as selected option. Tap on the box.
Don't choose "Never Allow". To send Premium SMS, select only "Ask" or "Always Allow"
Note: This is applicable with Samsung Android devices running with Jellybean 4.2.2
What happens when using different options?
1. ASK - It will ask to confirm if you allow the device to send SMS to the premium numbers. If confirmed, it will send. If not, it will not send.
2. NEVER ALLOW: With this setting, the device will never send SMS to premium numbers unless setting is changed.
3. ALWAYS ALLOW: The device will always send SMS to premium numbers. There are premium numbers that charges and some does not charge like Balance Checking with the service provider.
