Went down to the retail store to get the phone. No - sorry we can't sign you up for mobile - only business customers can get a mobile from TCL. This seemed a bit strange so I pointed them to their web site where under Home Plan there are pages on their mobile offering. I then asked them to call their call centre to check. And after some time on hold and navigating the IVR, they got to somebody who said, yes we can do mobile for retail customers but it's done over the phone and the phone is shipped to the customer!
This is probably not a big deal but given that the plans that Vodafone and TCL offer are the same, it's actually better in some respects to get a TCL 029 phone since you have a much better choice of number. If you want you can get your mobile number to be the same as your home number (I didn't). Anyway got back home, called the call center and signed up for what I wanted and the phone will be shipped to me in a few days.
I wish their retail store, which is really a customer facing outlet, knew what all TCL services were.
