I am having major cellular data connection problems with my White Lumia 900. I was experiencing the same thing with my Samsung Focus S I had earlier, but it wasn't this bad. Keep in mind, I have updated my Lumia with the fix they released mid-April.
Basically, when I am on the LTE and/or 3G/HSPA+ connection (not using WiFi), I very frequently lose my data connection. Sometimes the loss only affects HTTP/HTTPS (the browser stops accessing web pages, and apps that use HTTP stop working, i.e., RSS readers) - my mailboxes (using ActiveSync for all of them) still keep working. And sometimes EVERYTHING (including email) just stops working.
The only way I can really get everything working again properly, apart from restarting the phone, is to toggle the Airplane Mode on/off, to shut off/on the cellular connection. Once I do that, everything works again.. for about 10 minutes before I lose my data connection again.
This issue never happens for me when I am on WiFi.
Thinking it was a bad SIM card, I went to the AT&T store yesterday and got a new SIM card. No luck, the issue is still occurring.
Please tell me someone else is experiencing the same issue.. it is getting ridiculous. I can't even use my phone anymore in a non-WiFi environment if I want to check news, sports scores, anything. I can, but I have to keep using Airplane Mode toggle to get it working again.
Any ideas? Thanks in advance for any help.
