I am working abroad where there is no Lyric providers.
I wonder if there are contract/buying options;

a) to buy, get it placed/fitted and set from/by a provider and having one spare pair with me when going back abroad. Post one (or pair) back when there is a problem and expect the provider to post me a new one with my settings as soon as they get the not working one (pair). Assuming that I can arrange a doctor to fit (not set) in the country where I work.

b) to buy, fit and set myself in the country where I work. (receive the software and from the provider or manufacturer) Post one (or pair) back when there is a problem and expect the provider to post me a new one with my settings as soon as they get the not working one (pair).

I would love to hear if anybody had or heard something similar to my situation.
