EE cost of receiving unplanned call abroad, when using another company e-sim?

[paul_down_south]

 I am looking to use an E-sim for data abroad (not EE), and keep my EE sim on to receive emergency (family) calls when abroad.  How does this work on billing? I do not wish to buy a EU roaming pass, as it is expensive - how does billing cost per call or per text? I am aware I can tell the phone to route data through the other company e-sim.  Do I have to turn roaming on, but I don't get charged unless a call occurs?

I need to do this because my contract with EE for my family of 5, give expensive roaming compared to other companies and most e-sims

Depends on where you're going, check at ee.co.uk/roaming

The "e" element of your eSIM is immaterial here, that's a popular misunderstanding. You have a SIM with an operator, that's what matters. EE will charge roaming rates when you make or receive a call, send a text message or use mobile data - whilst roaming.

Roaming means using your phone on foreign networks, which is necessary in order to conduct any of those chargeable activities. The network connection itself is free of charge, the act of using that connection is what incurs charges - those charges are set out at https://ee.co.uk/help/mobile/roaming/roaming-costs 

Within the EU, roaming is flat-rate and not per-call or per-text. Outside the EU, you have both options.
