Hello @3sim ,
Welcome to the community,
You say you have a 3 sim data plan but one of the sims does not have data. Do you actually mean you have 3 SIM cards or they are 3 SIM cards? If the latter, you will have to speak to 3.
If it is that you have 3 SIM cards with EE that should all have data, then it may be that one of them is faulty, need more information in order to help you.
