I joined the club. Successfully unlocked an AT&T(Black) Microsoft Lumia 640 and am using it with my local cell provider (Viaero).
I couldn't resist the temptation and upgraded it to WP10. I definitely do not regret it, though the verdict is still out on if it is draining my battery faster or not. At this point I have to say it isn't as I can't noticeably tell a difference from WP8.1, though I only ran that for a couple days. It doesn't help that I work in a basement during the day where I get no cell service and that is definitely not easy on the battery.
My 1 question that maybe someone can answer me is if I can change the phone number for checking voicemail. The default button showing me that I have voicemail dials my phone number witch just lets me leave a voicemail for myself. I have a different number that I need to call to receive my voicemail. Is there any way to change that, or will I be stuck with a (slightly) annoying solution?
Edit: Found the answer to my voicemail issue.
