We got the service a week or so ago. I needed my immigration card, something with my home address (I had my Mexican Driver's License) and 3 people to "vouch" for me. Also, I needed almost $3,000 pesos to walk out the door with my modem. It took about an hour and a half. Half an hour to do the paperwork and a "wait" time (?) of an hour. I asked why the wait and I still have no idea. The 3 prepaid months are not for the first 3 months of the service, they are the LAST 3 months of the first year. I just got my bill for November. So, for me, I prepaid next year for July, August and September. I know that it is very weird and I asked twice if I was understanding correctly as my Spanish is just OK to survive. Yes indeedy I did understand. So, to sum up, you need to pay for the modem, a pro-rated amount for the current month and pre-pay for the LAST 3 months of the first year of a 2 year contract. You can get 1 modem for the first year and up to 5 thereafter. Even weirder, you must pay a 200 peso fee to continue with the REQUIRED 2nd year. Somebody spent a lot of time thinking these things up. The modem, like a phone reports your location. If you move your modem to another house, for example, you must pay an additional fee- the amount I have forgotten. The service is very good but the speed is variable. Early mornings I have gotten as high as 85 megabits/sec. and in the evenings -about 9 pm- as low as 8. 150 gigabytes goes very quickly if you watch HDTV shows with IPTV as I do. Add to that the computer and tethered phone and the gigabytes fly out the door. I still will get ILOX as planned and be happier with the unlimited data.
