Modem firmware setting may be changed.

Use system settings to choose tower bands.

[navaneeth8]

How do you do that ?

[Mayur000]

Dial *#0011#

You get system settings app.. if not wait for one minute.

From three dots, choose key input.

In that type Q0000
And press enter and wait for one minute.

Caution:

Plz don't change any option, you have to browse and find
ui settings..NAS....network control...band selection.

Sim 1 band selection...

Choose all bands
And apply.

But first note down all your actions in a book, so you can reverse it.
