Problems reconnecting to ee network when abroad

[Gordon250]

I'm abroad and been using a local SIM2, tried to switch back to my EE SIM1 and it seems to connect to the network ok with data and text working but I cannot make any voice calls on the mobile. Is there a settings change required?  I have removed the second SIM and restarted the phone. All settings seem OK for roaming.

You need to make sure under Mobile Service setting the “default voice line” is your EE sim.
