Is settext use mobile keypad?

one of my element unable to use setText
i am wondering if the setText use the phone keypad?
how can i tap on the phone keypad? so i can use the ENTER key to do text wrap as well.

at the phone, i can see the cursor is already pointed at the editor field.
but on execution, the setText cannot be used (i have use setText sucessfully at other element).
//At Composer, set message body
Mobile.tap(findTestObject(‘Object Repository/nine/Composer/android.webkit.WebView - Mail Editor’), 0)
Mobile.setText(findTestObject(‘Object Repository/nine/Composer/android.webkit.WebView - Mail Editor’),‘Test from mobile line wrap 100% & SGD$4.90 中文简体测试 line wrap END’, 0)
