If you want assistance from the Community Forum then you'll need to provide a bit more context and details than that.
When was mobile data working ok for you last?
Are your APN settings configured correctly?
Are incoming/outgoing calls and texts working?
Do you have an active membership plan listed on your My48 account dashboard?
Is it the €12.99 unlimited mobile data plan or one of the cheaper legacy plans with a limited mobile data allowance?
If you need to contact 48 support about this then see the links in my signature below.
