The island has DSL and Fiber services available for commercial internet with phone and TV. An UPS battery backup is recommended because of occasional power outages. Free Wi-Fi and computers are available at the Top of the Rock Commons for your use.
The phones here range in price from inexpensive disposable to high end. There are 3 carriers on the island (MEO, NOS and Vodaphone), with a wide variety of contracts. From MEO or NOS you can purchase internet service, cell phone and cable at local stores 5 minutes away from the Base. Some US tri-band will work if they are unlocked. Contact one of the cell phone companies for more information.
Want to call back home to the States really cheap? Get the hardware for IP-over-internet service (such as Vonage) with a local Stateside phone number before you arrive. It will work here, so when you call to, or receive calls from the States, charges--if any--will apply as if you were in the States. Skype* and other similar programs work very well too. Others swear by devices such as MajicJack.
The TV is PAL and the American system is NTSC. AFN is free on-base; off base you can get an AFN decoder at the Housing Office. AFN broadcasts 10 channels. Local cable is also available on and off-base from MEO or NOS. English speaking channels and channels with sub-titles are available. Satellite TV is also available off base.
