urm I changed my sim card a few months ago, or a few weeks ago I can't remember. But I chose not to change my number and keep it the same. So I did that. But its confusing how the number on messages is different.
um I couldn't find that, but when I went into my sim card status it shows my account thing and near phone number it says, unknown. Which is unusual because it has a section to edit but I can't add my phone number. So I went onto my Samsung account and my phone number is there so im highly confused.
Go to settings Then to connections When you select connections... Go down the list and item 9 is sim card manger When you go there.. Towards the bottom end you will see whether you have two plans, one for calls and one for messages..
