Airband fttp and current bt standard broadband

Hopefully this is in right forum. We live in a rural area which up until the last few weeks is only able to get standard broadband (not fibre). Airband have just recently installed fttp cables. Before I jump ship from BT is it possible to keep my existing broadband running alongside the new fttp? My reason being I work from home and have heard Airband isn’t the most stable so need to guarantee I can always get online. Likewise want to keep current landline (for now at least)

Airband FTTP is a completely separate service known as an Alt-Net (Alternative Network) so you can keep your existing landline and BT broadband going for as long as you want or need.

Of course the PSTN phone service will be stopping in a couple of years so you may need to review the situation before then, such as moving to a VOIP phone service if you need it.

That is possible. A better (and cheaper) option depending on mobile coverage in your area would be to use a 4G or 5G service as your backup, and port your landline number to a VoIP provider.

Don't forget Airband use CGNAT so you may want to have a static IP

I think that there is a distinction between Airband's fixed wireless network that by all accounts is awful and their FTTP. We have had their FTTP for nearly 30months now and during that time have had one significant outage of nearly 2 days, blamed on a damaged fibre and several few hour outages. I think these have always started late at night and are fixed around 8:30 the next day. (presumably when their engineers get into work).
They are not perfect, their routing is all over the place so pings are not great, they use CGNAT (I am paying an extra £5 per month for a static IP) and no IPV6, support is difficult to get any decent answer.
