Very good job! I found some minor issues after testing:

Initial text is „Click to update“. It stays after setting up the name. Good thing is that it will be replaced after restart. That was a bit annoying before - I had to press each USSD command to get names. Maybe this is not bad idea to put this text as default name.

It shows status (Processing/Error) after name. Currently I have to add extra space after name. Maybe you can add hyphen between them. I would prefer if the name is replaced with status or result for few seconds, so I don’t have to reserve extra room for expanding. I hope you can implement a message box also in future. After that it will be perfect.
