Smart meters and prepay

My current electricity meter is a conventional credit meter, and I am looking to install a smart meter from Bulb, my electricity supplier. My understading is that Bulb installs the EDMI ES-10A electricity smart meters. Also, my understanding is that currently Bulb cannot support prepay plans with smart electricity meters. If I install the EDMI ES-10A smart meter and I decide in the future to convert my credit plan into a prepay plan, will the EDMI ES-10A support this, or will I have to get a new smart meter? Also, does Bulb have any plans to install the EDMI ES-10B smart meter, which is the successor of the ES-10A?

Thanks,
