Online CPC renewal

Hi folks ive got 28 hours of cpc banked from my ADR course so i only need to do tbe one 7 hour course.
Is a mobile phone sufficient to do the zoom class online or would i need a larger device.
Also ince completed my 35 hours whats the process to get my new card sent out to me.

As long as you’ve got a camera phone
The app of said trainer and enough battery life a phone is ok
DVSA will automatically send card out once final hours are banked

The cards are seemingly sent out well in advance now. The new card is valid from the date of issue, but will run on until an expiry date 5 years after your present card expires.
