Your post is confusing.
The title says that your data doesn't work but the body asks about "charging" your number.
You'll need to clarify what exactly the issue is.
What are you trying to do, what steps are you taking to do it, what happens/goes wrong, any error messages?
What does "charge my number" mean?
When did your data work ok last?
Are your APN settings configured correctly?
Text "APN" to 50048 and follow the instructions here to ensure that they are:
Are calls and texts working ok?
Do you have an active membership plan and a non-zero data allowance balance?
If you need to contact 48 support about this then see the links in my signature below.
