What are your tips on glasses? I choose standard uncoated lenses nowdays after finding that anti-reflective/anti-scratch coatings often scratched easily or had an optically-rippled surface, but maybe things have improved?
If that’s the main problem then that’s easy to solve! Simply use a free public xmpp server.
I mention the self- and paid-hosting options because businesses tend to like having a sevice agreement backed by a contract, and may have additional specialised requirements not provided by free services (xmpp or otherwise).
XMPP. A business can self-host, there are public servers, or there are many businesses which offer customised xmpp hosting as a service.
I can be federated with other xmpp servers or be a locked-down work-only service, or federate with chosen other servers (such as a client company’s xmpp servers).

Some 4G phones don’t support 4G calling correctly or with all networks.
Check whether your phone actually uses 4G (VoLTE) for calls – to sort-of test this, make a call while connected to mobile data and note whether the signal meter’s 4G indication drops to 3G(H+/HSPA) or something during the call.
A more insidious version of this issue is that some phones do VoLTE just fine, but only use 3G for 000 calls.
Some phones only support VoLTE with some networks. There’s a chance that an appropriate firmware upgrade could add support for some network/device combos.
