Roaming worked fine till yesterday morning when I was in Delhi & Dubai. This issue started only after landing in USA. Does it need any special setting in Lenovo K50a40?
Expert:  Richard replied 9 months ago.

If it does, you will need to get this from your carrier but this is always automatic.

Can you contact your provider and see which settings they require you to set please.

Customer: replied 9 months ago.
I had checked with the carrier. They checked and confirmed roaming is all right and suggested restart the device. Which I dod but didn't help.
Expert:  Richard replied 9 months ago.

Then we will need to do the reset, if they confirm the settings.

Can you backup all data off the phone please.

Customer: replied 9 months ago.
The suggestion to reset to make Lenovo K50a40 working wasn't right.
Seems the handset is triband and most places in USA needs quadband. I have come to Europe yesterday and the same handset with Airtel India sim started working automatically.
Thank God I didn't reset the phone as per suggestion. My phone had several business critical data & corporate apps. Losing them / backup-restore would have created a challenge but wouldn't have solve the issue.

Analysis from Matrix is attached - also mentions triband issue
