Purchased a 32GB 3G Nexus 7 from Google. First one had a cluster of dead pixels so I returned it along with the Micro-SIM it came with.
They sent me a replacement, but it did not come with a Micro-SIM. So, I had some back and forth emails with Google for about a week, trying to get them to send me a Micro-SIM. I ended up just going to an AT&T corporate store to get one.
That was yesterday. I've had this Micro-SIM in the N7 now for a day and I did pay $15 to activate one month / 250MB of data just to try it out.
It works, but I keep getting two different messages on the screen randomly at different times, that say:
I press the restart button and once it's on again and on the pin screen (where I enter my 4-digit code), it says, "NO SIM CARD" beneath the number pad.SIM card removed
The mobile network will be unavailable until you restart with a valid SIM card inserted.
I'll proceed and enter my pin. Do some stuff, play games, check email, just use it regularly and all of a sudden I'll get that SIM card removed message again asking to restart the N7.
The other message I get as well (also randomly) is:
SIM card added
Restart your device to access the mobile network.
Anyone know what's 'causing all of this? Any fixes?
