I ordered Flash internet from VZ in Higuey. It took 10 days to get the phone line installed (that was the biggest problem) - there were no "free wires" in the area and the tech had to bring in the line and wire from another area - cost me 1500 pesos. After the line was installed, internet was up and running in 5 days. They gave it 2 weeks turnaround time after line installation, it was upa nd down (more up) during those 2 weeks, but after that time it was up straight.
So VZ took only 5 days to activate.
The line was in my ex-wife's name, but according to the sales rep it would make no difference. We just put it in her name because with her cedula we saved 2 days it would take to fax passport to Santo Domingo and get account number for me.
Also to mention, I ordered new line and internet at the same time.
The sales rep (Lucy) was very helpful in pushing the technician to make the line installation and gave me his private cell number to coordinate with him the installation (after it was determined that there were no "wires" available in the area). VZ would return the order back but she put it on hold and I resolved directly with the technician.
I am getting the internet from cable company now, because I would pay 600 pesos less for the same speed (768 kbps). Awaiting installation this week.
