As per 3GPP 29.272 spec, there is no max limit on APN configuration however a LTE UE can have maximum 8 data radio bearers at eNodeB and each data radio bearer is mapped to corresponding EPS bearer in EPC. All eight bearers might be combination of default and dedicated bearers.
Usually, I have seen one APN for internet and other one for IMS. In this way, total three bearers (1 internet, 1 IMS signalling and 1 for VoLTE call) will be used for these two APNs. Remaining five bearers can be used in any combination of default and dedicated.

Is there any way in UE settings to initiate connection with multiple APN simultaneously ? Or even one by one is also fine .

Can't find how many max APNs UE shell support simultaneously, please share the thoughts. Is there a relation with number of bearer?
