@Anonymous Have you switched your phone off and back on again? How long ago did you do the swap? It can take 24 hours for it to register on the system.

switched it off didn't work. about 3hrs ago now. my new nano may not be activated. says emergency calls only

Has your old sim lost service yet?

[Anonymous]

no

Then do the swap again or use the form

do I need to activate new nano SIM first

looks like I gotta wait longer. just tried doing it again and had text saying it's currently in process. thanks all for help👍

It won’t start until tomorrow.
Once your old sim switches off reboot the phone with the new sim in every half hour.
It may take upto 4 hours to come online.
