Your post was blank @Damienc2780 and the subject line doesn't really explain your issue clearly.
If you have a question or an issue that you need assistance with from the Community Forum then you need to describe/explain it clearly.
What exactly do you mean by "data only SIM card"?
48 don't provide data only SIMs.
Only SIMs that support calls, texts and mobile data once you have a monthly membership plan giving you allowances for each of these services.
What exactly are you trying to do here and what exactly is the problem.
If you need to contact 48 support about this then see the links in my signature below.
