are you kidding me??
the 8110 4g can't handle a second call on hold?
i tried to configure the system to be able to have a second incoming call signal when i'm already in a conversation, and it doesn't work.
with the sim on other phones (including an old Nokia 7020) it works properly, when i put the sim on the 8110 4g i just have a "busy" signal on the caller and an sms "i've called you" on the 8110.
it's 2018 FFS!
that's frankly unacceptable also for a 80 bucks plastic phone!
