Brought a UK sim free Lumia 800 with me to NZ - had the phone in the UK with an Orange SIM in it with no issues for a couple of months.
Bought a Vodafone plan, and put the sim in.
Some days the phone reboots around 30-40 times, some days about 10. But it constantly reboots of its own accord.
I've just swapped the handset with Nokia Care for a sim free one from Australia - same symptoms.
Also swapped out the micro sim with Vodafone for a new one - same symptoms.
Its a real shame theres no error log or eventvwr in the phone anything to tell me whats causing the phone to reboot like this.
The orange PAYG sim from the UK doesn't cause the phone to reboot at all, has anyone else observed this behaviour, and could it be some data being sent to the sim (do they poll) that causes it to just crash & reset?
If someone from MSFT is here and fancies picking this up - or telling me how I can get to a log file then i'd really like to solve this - it's driving me nuts now.
p.s. I have the date time "out of sync" issue as well.
