Those are "single threaded" data streams. So if you are making a phone call on a non-GSM network you engage both the up and downstream channels for calling.

Remember mobile broadband services are very similar to Dial-up services. You have have a 64k data stream and still use your landline or you can use both 64k lines for a faster connection(I think this may be ISDN IIRC)
You're aware that some networks only supply single sim devices. The dual sim capability is not enabled by software blocks, like on some older Hauwei devices.
Do you understand now why the second sim card isn't working for the person I was replying to?


I did type slowly, incase you read slowly.
