I used to have an hobby phone paid with cash, etc. We all value our privacy and safety. But I have to admit, it was a pain in the ass. I would barely use it, and even though it was generally based on prepaid us, I would have to pay to recharge it every 90 days or so even if I didn't use it. So when it died about 3 mos. ago, I let it stay dead. Frankly, I haven't missed it. I usually book by PM, where new providers can see my reviews anyway, or email, and if someone asks, I say "don't have a hobby phone right now." It really has not been an impediment.
But today I tried booking with a relatively new provider by PM, was in the process of scheduling, but was eventually told "I don't give my address on eccie ... or email." Really? Like it's more secure on a stranger's text message (e.g., where an SO can find it)? I didn't argue about it - the way I look at it, if she doesn't feel secure, then we wouldn't have fun anyway.
On the other hand, one well-known/well-regarded provider I know strictly uses email.
I was just curious and wondering about communications habits of others. Specifically, in this stage in communication technology, do/should we really need hobby phones as hobbyists? Or providers?
