My phone is sometimes normal (I can text, call and use data with no issues), and sometimes, randomly, goes in "roaming" mode. I am always "roaming" at home and at my office. I have a phone-intensive job and I do -not- appreciate having to go on the sidewalk and wait until the phone stops being on roaming before I can call people.
Is there a way to stop it from happening? And worse - it lets me send and receive texts even when roaming, am I getting charged extra money every time I do that?
I am unable to turn data and voice roaming off (the option is greyed out on my phone, I can't tinker with it), so I have no idea what to do.
I have a Samsung Galaxy J3.
Thanks in advance!
