Flash the latest factory image.
My N7's baseband version is M9615A-CEFWMAZM-2.0.1700.98, so I think you have the 4.3 baseband which is incompatible with the 4.4 roms, that's why you don't get service.

Did you reboot the phone after inserting the Sim card or enable airplane mode on and off?

Best solution is try some another "micro sim".
DONT cut it but bring it from your service provider.

From what I know I believe the sim cards can have hardware within 1/16th of an inch from the side, or it might have been 1/8th but yes dont cut the card, um I know it sucks but back up what you can with something like titanium backup, then try undoing what could be the cause, so flash stock rom. With titanium backup you just hit backup/restore then the checkmark in the top right then scroll way down and hit restore apps/missing apps+sys data... if it fixes the problem then great but put a copy of the backup on your computer in case the extsdcard gets wiped too for some reason or in case you have to send it in

Ill ponder for a while and see if I can brainstorm a solution, ill ask around a bit and see what I come up with,
If your worried about your warranty and your carrier won't help you, I suggest going to best buy and letting the Samsung guys take a crack at it, they have the proper software to find the problem.

mejakola · Mar 23, 2014

OK when you first got the phone was the sim working?
Is it a carrier specific device?
If yes are you using a sim card from that carrier?
Is the phone unlocked or factory unlocked or is it locked?
Was there any thing you did such as flashing custom roms?

I think it may have a bad Imei but I'm still trying to figure that out

dont know if you ever got your issue fixed or not, i had a similar problem the other day on my galaxy s4 i337
i was able to make phone calls and recieve text messages but i could not access the internet through the network, my carrier actually did something that helped but didnt fix it... the technical support team had me turn off the phone and then they erased me from the network, so when i turned the phone back on the phone rebuilt the network through the sim card and for some reason i have better reception now...
i still could not connect to the internet via wifi or mobile network so i factory wiped and installed the stock firmware.

do you have somewhere to go where they can "officially" flash the stock firmware? here in the usa i can take my phone to BestBuy, a large electronics dealer, and they have a samsung area that the people have the tools to do so.
maybe your network carrier can help you, maybe its not a phone issue but rather a network provider issue.

Mkay I'm not real sure about that so I would check the forums for your phone and see what you can find since you narrowed down the problem

It's a little bit strange but you can try to use an adhesive tape on the side of sim card to prevent a short circuit between contacts and the sim card's metalic tray.
It worked for me.
