Hi there and welcome
You will need to have a computer to do this sorry, you cannot get around this.
It does not need to be your computer, you can use someone elses to do this, then you follow the instructions here
They are very straightforward, but it has to be done via the computer sorry
If you would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
