I have the Lumia 900.
Here's what happens to me occassionally. I'll lose data connectivity for short periods of time. Phone shows a 4G connection with 4 bars, but my data connection just stops. At least once I had to actually cycle the Cell radio Off and On to reconnect.
I'll be at home with both WiFi and Cell turned on. Things will be working fine and then I'll lose the data connection. IE won't connect, Marketplace won't connect, Games won't connect. First couple of times this happened, I turned off all the RF (Cell, WiFi and Bluetooth) and then turned them back on. Data began to flow again. Happened again over the weekend, but this time I turned off the cell only and then turned it back on. Data connection returned. A little while later, data dropped out again, only this time I turned off the cell and whileleaving it off continued to use the WiFi and the connection returned.
I don't understand why I'm getting dropouts at all when only on Cell. Don't understand why I'm getting dropouts when I have Cell and WiFi, and really don't understand why I can restore the connection when I turn the cell off when I should have only been using WiFi to begin with.
Has anyone else seen this kind of problem?
Is this some screwy SIM card problem?
