Networks?
There will be many listings that say GSM or "works everywhere".
Not always true.
Here are the facts on which carrier uses which band in the DR:
Orange UMTS 900; GSM/GPRS 900/1900
Claro UMTS 850; GSM/GPRS 850/1900
I found some phones that only had 850/1900
And others that had NO 2G bands at all and the title said GSM.
DR Specs found here:

I did this with an ATT phone.
ATT has a special webpage to request the unlock code.
If the contract was paid up and finished, or was a prepaid phone, they will give free unlocks.
att.com/deviceunlock
You need a SIM chip from some other carrier to do the unlock.
OR use a friend's chip from another carrier.
OR take it to some tech repair place.
OR buy the other chip from seller on ebay for a couple bucks.
