[Q] No service-insert SIM card on GSM Nexus

I'll occasionally have my phone drop my connection to the network and claim that it has no SIM card inserted. I'll turn off the phone, pull of the back, remove and reinstall the SIM card, and turn the phone back on. Most of the time this fixes the problem.
I've noticed it seems to happen after my phone gets hot (using Google maps navigation, playing Ingress, etc.) I'm not sure if this causes it or not, but it's something that I've observed.
This seems to be happening more often than it used to.
Any ideas on how to prevent this from happening again? I need a reliable phone when I'm on call at work.
Thanks!

TOOL Bypass Google Account Verification - Anyone, take a look?

Hi,
Tried to resolve the Google Verification by this tool.
Looks like everything went smouthly.
I did that bc's after trying to use the phone with a new SIM and it gave me the Google Verification thing.
Maybe it is a stupid quesion...but:
If i successfuly inserted the new sim (and it working) after completed the the first boot without the new sim(Language, Google and so on) and it worked => it should'nt do any problems with this verification anymore?
Thanks!

Doesn't work on Flex 2 ATT

Service message center option is read only (greyed out)

Hi,
I just replaced my sim card on an LG G4 (H815)
I can no longer send text messages.
I went through the options and saw the message center number is incorrect (it's configured to be for subscription customer and I'm on prepay)
The option however is greyed out and I've been struggling for the last 2 hours to find a way to change it to the correct one.
Here is a screenshot of the problem

Problem solved
In case anyone gets to this problem, I was able to fix it by putting the sim card into another phone that has the ability to change this service center number.
Once I did that, I put it back into LG G4 and it worked.

Airplane mode is toggled when sim is installed

When I install sin in a sm-975u note 10+ us version, the airplane toggle lites up halfway dim and no cell service icon is where the signal level is normally the screen has been changed and the boards seem to be correctly matching. When I got the phone it was Google locked I paid an ebay company to fix and seems they did fix frp. The phone had Verizon icons I sold it to a friend he put a at&t sim and the phone didn't work so I put a verizon sim in and no luck. I did a imie on byop on verizon and swappa phone is good to go
