Ok, I should be receiving my dual sim Lumia 950 sometime today. My carrier is AT&T and I am coming from a Lumia 920. Since Windows 10 still unpolished, buggy in some instances, and this particular phone not sold by AT&T, I have a few questions to have the best experience possible. After most of you have chimed in, maybe somewhat can recap the most useful and relevant suggestion and make it a sticky for new buyers.
1) Since I am coming from a L920, I don't have an activated nano sim. Does the Lumia 950 have to have the sim activated and installed before turning on the phone for the first time, like it was the case for the Lumia 950 XL so AT&T can recognize it?
2) Is the Dual Sim L950 IMEI recognized by AT&T or, (contingent to the answer of question #1) would I need to provide AT&T with a previous IMEI or a ATT version L950 for it to work properly?
3) I have seen here that people suggest updating to the latest firmware/and OS build and hard reset the phone afterwards? Wouldn't a hard reset roll back to the build original installed in the device memory? Or does it pull the latest build from the cloud after a hard reset?
4) Contingent to the answer in #1, #2, and #3, Can I run it sim-less, set it, update, play with it, and then install the sim and do a hard reset? Will this be exactly the same as original factory state? What I mean, assuming it has the same issues as the 950XL, Daniel R. article suggest to either have the sim installed before the first set up, or obtain a working IMEI to trick the ATT system into activating the sim properly. He never suggested in that article that you could, after the fact, hard reset the phone, and it would act like if you have the sim installed before turning on the phone the first time. Hope that makes sense.
5)From what I have read, to avoid any risk of more bugs introduced, a clean setup is recommended. I don't care to use my back up as I can download most of media stuff and apps separately, at a later time. The only think I would care is my text messages and Whatsapp messages. I don't think I can export/import the whatsapp messages, but is there a way to import text messages at a later time? Not big deal for me, but preferred if I could.
6) Has the messaging backup thing where it was excessively consuming LTE data being resolved as of .107? OR should I keed it off for the time being?
7) Lastly, I think it is all about downloading apps, optimize battery setting etc.
Thanks in advance for all suggestions.
