How many operators and ISPs are there in Nigeria?

Telecom service in Nigeria depends a lot on the location in the country. I have compiled information on what is available as far as mobile ISPs in the central city of Jos, and much of it will apply across the country (as far as types of service, prices, and so on) but the availability and particularly the actual effectiveness of the plans will vary depending on location. See Mobile ISPs in Jos for a summary, and feel free to add more information there as well as in this wiki.

• N6,300 to N15,750 per month for home plans
• when working well, have had speeds over 1mbps download
• squid proxy server flakey and DNS infrastructure not solid

• WiMax with interior or external antenna, I'm using external

• speeds are really variable
• DNS infrastructure problematic

• VGC communications, now owned by MTN
• Despite using this service for more than a year, I know little about cost
• ADSL provider
