Here is a few things I have learned since the last post.
1/ To conserve data (since my prepaid card only had 100mb) is to goto play store>> settings> turn on "update over wifi only"
This will prevent you from going to sleep and find out the next morning that half your data lan has been used up updating apps
2/go to menu>>settings>more>mobile networks>> turn on data roaming.
A few irritating features
Each time you boot the phone, it will ask you to input the SIM card passcode
Then when you swipe the phone open it will put up a statement that "a non network sim card has been found" You will need to hit OK
Then it will search for a CDMA carrier which after 15 seconds it will tell you that no carrier was found, switch to global mode. Hit OK then the phone will then find carriers
I flew today from Hungary to Switzerland. No service with my Hungarian SIM card (T-mobile). After speaking with some ex-pats they said that you cannot get interational roaming with pre paid SIM cards. Maybe if I went with a provider like Orange that spans many countries, it might have worked
Anyways, I decidd to reinstall my verizon SIM card
I booted the phone and no service.
I then went online and upgraded my monthly verizon plan to add international roaming.
I waited and nothing
I re booted my phone and now I had 3 bars wih a little "R" above it and I was able to make calls
I had no data.
If you remember from a post aobe that I have canged my APN settings
I went to menu>>settings>>more>>mobile networks>>network mode and changed it from global to GSM
this now allows me to change the APN
by going to menu>>settings>>more>>mobile networks>>acess point name>> hit the menu button and select reset to default
then reboot the phone and now I had data
I will post again when back in the US and I immediately received tex messages from Verizon re cost
At $20.42/MB of data I went to menu>>settings>>more>>mobile networks>>and unchecked data endabled
By the way I set up a textPlus account by Pinger and the free WIFI calls worked great
I had my Google voice number ported to my textplus number so all my US textmessages and voice mail came to my phone for free
The prompting for the SIM card passcode is associated with the SIM, not the phone. You should be able to remove the passcode from the SIM if you want to. Also, when using a foreign SIM, go to Settings -> More -> Mobile networks -> Network mode and select GSM/UMTS. This should keep the phone in GSM mode and completely cut out the futile search for a CDMA network.

The SIM passcode is something you control. A reboot of the phone will not change it. Go to Settings -> Security -> and scroll down to "SIM CARD LOCK." If you change the passcode, or if you remove it, that change is programmed into the SIM. A reboot of the phone will not change it back. The phone has no way of doing that, nor does the SIM, once you've changed it. It would be like you setting a password for your email, and then after rebooting your computer, your computer or email provider up and changing your email password. If you don't remove the passcode from the SIM in the settings for the SIM, it will ask you for it each time when rebooting the phone. If do you remove it, there will be no passcode to enter.

Shortly after getting up and running, it asked me via a popup if I wanted to switch to CDMA/LTE mode since it couldn't find a GSM network. In that popup, it also gave me an option to remain in GSM mode and never have that popup appear again. Upon boot up, if yours says something about a non-network SIM (which it never did on mine), and if it's searching for a CDMA network, it sounds like you have it Global mode and not in GSM/UMTS mode.
So again, you can remove the SIM passcode and you can manually put the phone remain in GSM/UMTS mode. Turning the phone off and then on again at a later point will not change either of those if you get them setup correctly.
Sorry for the confusion. I did not change the SIM code. I just have to input it again everytime I boot the phone
Update from SDFSMC:
I ended up using Verizon's international rates and data plans which cost $5 and $25 per month. I activated the plans the day I left, and shut them off when I returned. I also shut off the data functions in the background as outlined above, and used any free wifi networks I could find to collect my emails.
The fees were prorated for the 1/2 month I used them resulting in about $30 cost per phone. I would have preferred to have the normal functionality but $30 was a reasonable amount to pay for the security of having the phone while I was away.
Thank you to all of the members of this forum for your help and advice.
I am taking a trip to europe next month. I plan to only use the phone via WiFi, and only make emergency calls if necessary if WiFi not available. Do I need to activate my phone for international use before I go? What settings should I use on the phone to prevent any un-intended roaming and data charges?
If you're only going to use it via WiFi, then there's no need to activate anything for international use. Just keep the phone in airplane mode while you're gone (you can enable and use WiFi while in airplane mode), and you'll be good to go.
