You should take care walking around the forum area at night. Caracas
GSM/GPRS services are available in the whole city, and are provided by Digitel TIM (734-02). Those of you with a GSM-enabled phone can just roam into the 734-02 network (as soon as you turn on your phone you'll receive Spanish messages with the information of use).
If you have a CDMA/TDMA/CDMA20001X phone in a network which happens to have agreements with Movistar or Movilnet, you'll have service here too. If you don't, you can buy a SIM card (around £10) from Digitel for use in Caracas and the surrounding area, although they will not always work on foreign handsets.
Communication Centres, Internet Points and Public Phones are everywhere. The international code for Venezuela is 58, and the local area code for Caracas is 212.
