Cannot send messages when browsing in offline mode

This means that your phone is not connected to the cellular data network. Check your settings and make sure you are not in "Airplane Mode" or that your cell phone is receiving a good data signal.

Cannot send message.always message sending failed. but i have outgiong calls and incoming message. then when i put my sim card to other phones, it works smoothly. it can send messages


If you happen to have another sim card with you, can we try to use that sim card and see if the phone will send.
Or your sim card on another phone.

-This is to identify for sure is the issue with the phone or sim..

-If you cant send using another phone then get you sim changed or check with your operator.

-If you are able to send on another phone then you may wanna try resetting your phone by following these steps:

- A restore by keying in *#7780# when on standby - This will not delete any data but will restore all the settings back to default.

If that does not help then you may wanna try doing a soft reset by keying in *#7370# when on standby - This will reformat the phone. DO NOT FORGET TO DO A BACK UP AS THIS WILL ERASE YOUR ENTIRE PHONE MEMORY.

The security code by default is 12345

If this fails as well then you may try doing the Hard reset by performing the 3 finger reset. You can do this by switching the phone on with the '3', '*' and green 'call' buttons pressed at the same time.

I can't browse the internet using my Samsung Star Wifi. Everytime I try to browse the net, the DNS Failed message always appear. How can I solve the problem?

Ask your network operator to send you the internet settings,install the settings and set them to default for your browser.After that restart your phone. If you already have the Internet Settings on your cell and internet is activated on your number then you should delete your settings and ask your network operator to send you the internet settings again, install them and set them to default.
You should also do one more thing i.e, reset your cell to default settings or if you have the option of reset browser then only reset that.
Thank you!
