Cat B15Q pairs with Toyota, but connection unusable
Last week, I had to turn in my (company car) Toyota and I got a Peugeot 2008 in return. Of course I tried to connect the Cat to the car. Pairing was no problem. Making a phone call, however, was not possible. But receiving a phone call was possible! This got me thinking. The Cat is dual SIM and in fact I have two SIM cards. In the settings you can choose which SIM card to use as default for outgoing calls, or whether to postpone that decision when actually making a phone call. I had chosen for the latter option, but after I changed it so that outgoing calls always use one specific SIM card, I could make calls with the car's phone buttons!

Maybe the connection with the Toyota had been successful after all, it just got stuck because I hadn't opted for the default SIM card option.
