Activation Incomplete

[Rusty3]

Every time I turn on my phone the following pops up:  "Registering the device with the network".  After a minute or so I get "Activation incomplete.  Internal error (407)."  The phone works fine around Toronto, but I have been out of town and it doesn't work.  How can I fix this "activation" problem?  Thanks!

@Rusty3 Another suggestion from:

https://us.community.samsung.com/t5/Galaxy-S-Phones/Internal-Error-407-and-700/m-p/1360094

Go to 'Settings' > 'Software update' and hit 'UICC Unlock'
It loads for a moment, then says SIM Restricted... Hit 'OK'
It takes you back to the 'Settings' > 'Software update screen'. Hit 'Download and install'
It loads for a moment, then says Your software is up to date...
Then open that notification saying the profile didn't update.
It loads for a minute, then says Profile updated... Hit 'OK'
It loads again for another minute and says something similarly. Hit 'OK'

@Rusty3   do you have a Samsung phone?  Did you get this phone from US?  

I saw people with this issue for phone that they got from Sprint.    Some people have to Factory reset the phone to fix it

I don't want you to reset the phone yet.  Try to first reseat the sim card, power off phone, take sim card out for a minute before putting it back and power up

Next to try , try to put another active sim card from any provider into this phone and see if it works
