Send a long message via KDE Connect and verify that it is actually sent
Send a short message via KDE Connect and verify that it can also be sent
Ideally: Test sending a message which is the maximum length for an SMS (160 characters) and verify that it is sent as exactly one SMS (And billed properly)
Receive a long message and verify that it is delivered as a single long message, even though we all know that it was transmitted as a multi-part SMS
Receive a short message and verify that it is correctly delivered
