Text messages take forever to go through?

I have an iPhone 4s, I think something is wrong with it. Whenever someone texts me it takes like 10 minutes for the text to go through.

My mom texts me something from upstairs and she told me that she just sent it but it doesn't pop up on my phone for what seems like forever.-. She has the same problem when I send her texts too. She has a Samsung Galaxy.

And if I put my iPhone on tmobile will I have the same number?
