just to let you people know you can take one of your cellphones here from your country and it can be activated for use with a calling card. a small fee of 300 pesos will apply.You will need a receipt of some kind . The government here needs to know its not stolen. This activation can be done in 10 minutes to 24 hours. It all depends on weather the phone is new or old. newer phones will be 150 pesos more,because the programing of the phone is tough to obtain(new to this country) IF you are on a business trip here it is great to have phone use for a month .Anything over a month of non use will be disactivated automatically. I am thinking of starting a cellphone sitting service(you heard it here first) where I could hold businesspersons phones and introduce a calling card once a month so that person would be able to hang on to the same telephone # .they then could actually make up business cards here. contact me at soscellular@yahoo.com or call me carlos at 809 596 1205 we speak spainish and english
