Advice: Verizon TP2 in Ecuador?

I'm currently running the excellent and fast Mighty ROM on my Verizon TP2. I'm thinking of going to Ecuador. I hear they use "GSM-850" networks with SIM cards. I've heard that MightyROM won't work on GSM networks.

Should I unlock the SIM card and flash back to the stock ROM?
Are there fast GSM-based ROMs that should work in Ecuador with a SIM card purchased there?

Thanks in advance!

I have been following international use on the forum and you are the first to Ecuador. Unfortunately I know more about Sprint than Verizon. I am afraid I would call Verizon and see if they have an international dataplan like Sprint. This is what I have used all over with Skype to cover the voice. Has been very cheap.

Please report back what you do and how it worked for the records here.

why wouldn't mighty work with the proper sim card??? you can't flash mighty to gsm only phones, but this is a different situation.

Yes it should work but you need to call vzw global services and have the sim card slot unlocked.

I would flash your phone back to stock if you are going to be traveling internationally.
There are some settings especially for GSM data that are a pain to set on non stock roms.
A stock rom ensures that your phone has the correct APN set for Verizon global data.

Voice roaming is extremely expensive on Verizon, expect to pay $2-3 a minute.
Data roaming is expensive unless you buy their Global Email plan, it is $65 dollars a month.
So if you have a $30 data plan it will be $35 extra for the month.
If you are only going for a week they will prorate it so that you will pay much less.
