Just got a new phone (Huawei Mate 10 Pro), so in a similar fashion to previous, I've put my share data sim (2015) into my Xperia Z5. To my surprise, I am unable to access the Mobile Data despite the fact that the data sim card works on my older Xperia Z3.
I've also attempted to put it into my brother's Xperia XA Ultra and it works!
I attempted to put my regular sim back into the Z5 and it also works!
What can I do to let my Z5 run mobile data from the shared data sim?

Probably because the APN setting is not correct for that plan on the device.
Shared Data plans use the APN of connect
