Using Vodafone India SIM (activated) in US I am unable to send or receive text
I have a phone used in India with a Vodafone SIM card which is active. The phone is currently in US and I am unable to send or receive text messages.
As a trial, I took out the SIM card and placed in a Samsung S4 and I am able to send and receive text.
What is the issue with this specific phone or it's settings that is causing this issue? The device is Samsung Galaxy DUOS. Does it have anything to do whether this device is locked or unlocked?
