My Samsung S Duos 2 mobile connection is not working

Hi everyone my mobile data connection was enabled, but the connection at the top E or H or 3G does not appear on my phone. What would I have to do? I turn it on and off, but nothing happens. I cannot connect to the Internet because it says no connection.
yesterday I changed my sim card from globe to smart then I used the internet connection on my smart sim then this morning I switch back to globe sim as it is my original sim then I tried using the mobile data connection and its not working no connection at the top but my mobile data is enabled. can anybody please help me with this? I already tried turning it off and on again I even took out my sim card again but nothing changes
Thanks in advance have a great day and God bless

Do you still have a Globe account? If not, you can't use their SIM for anything.

If you do, try putting the Smart card back in - if it doesn't work, something went bad in the phone.
