I would call Verizon tech support and have them send a signal to your phone/sim card to make sure its sending and receiving properly

Maybe check your APN settings, perhaps they need to be updated. If you're having trouble with a specific carrier card, but a different carrier card works, I would start there. It's an extremely quick and easy fix if that truly is the problem.
Do a quick search around here; there are many threads dedicated (or have info) to new and different APN's.

Can a phone prefeer some operators?

Hi,
my no-brand Galaxy S III GT-I9300 was working fine running CyanogenMod-13.0 nightly with my Vodafone Italy sim card, until I used for some weeks a sim from the italian operator Tre. When that contract expired I discovered that my phone didn't accept anymore sim cards from the italian operators Vodafone and Wind (it shows a message complaining that there is no sim card), while it works fine with the italian operators TIM and Tre. Sim cards that my phone doesn't accept are well working in other phones.
Previously all sim cards of all operators where working fine.
I tried the following with no result:
1)- wipe all user data;
2)- install the original Samsung firmware JSS15J.I9300XXUGOE1, followed by another wipe user data;
3)- restore from a full nandroid backup, including modem, system, user, cache partitions and EFS, taken when everything was working fine.
I've checked my IMEI number on some websites and it seems to be clean.
All the hardware in my phone, including the sim card reader, should be fine because everything works when inserting TIM and Tre sim cards.
Can anyone give me some help?
Thank you in advance.
It is very possible that tre have locked the network lock but not only is it bad practice but also at the end of any contract, providing it is paid up in full, the operator is obliged to unlock the network lock free of charge.
The best way to start is to call tre and ask if they have put a lock on it but just habe a look at the sim cards first and make sure they are the same where the gold contacts are.
If the other sim cards were active and not used within a certain timescale, usually 6 months, the sim card will be remotely deactivated and the number returned to the pool for someone else to use. Im this case you must realise that you simply "lease" the number from the operator. You never own the number, only the simcard it was attached to.
If your rom is 4.2 you can unlock it yourself by changing a byte in nvram, very easy to do.
If your phone has ever seem 4.3 or later you can't unlock it without a proper network key.
A word of warning though. Be careful with the efs partition.
