Ten Turkish cities are getting major speed upgrades from their fiber-to-the-home provider Turkcell, which announced this week they are doubling the speed of their basic plan and introducing 1Gbps service.

“Through our investments, amounting to nearly $890 million U.S. dollars over the past three years, Turkcell Superonline has continued to pioneer the fiber-optic era in Turkey,” said Turkcell CEO Süreyya Ciliv.  “Now we are proud to provide a 1,000Mbps Internet speed service in Turkey.”

Superonline General Manager Murat Erkan announced current budget plan customers would get free speed upgrades from 10Mbps to 20Mbps, with no rate change.  Budget plan customers can choose from a usage-limited plan offering 4GB of monthly usage for $18 a month, or unlimited use for $31.

Higher speed unlimited use packages are already available, including 50Mbps for $63 a month and 100Mbps for $126 a month.  The new 1Gbps package is pricey by any consumer’s standard — $634 a month, but even at business rates is a bargain for any company paying for dedicated data circuits. Turkcell even offers a pay-as-you-go Internet package for many of their speed tiers.  Pay $3.17 a month for the connection and around $5 per gigabyte of usage.  On vacation or away for an extended period?  Just pay the connection fee — no usage charges.

Fiber service is currently available in Adana, Ankara, Antalya, Bursa, Istanbul, Izmir, Gaziantep, and Kocaeli.  Two additional cities will be wired by the end of 2011.

For the rest of Turkey, ADSL, bonded ADSL, and some ADSL 2+  service predominates, with speeds ranging from 2-16Mbps.  Unlimited and usage quota packages are available starting at around $18.40 a month.  The first six months of service are provided at a special discounted rate of $6.33.

In comparison, American cable company ISPs charge an average of $40-50 a month for 10/1Mbps service, $50-60 for 20/1Mbps service, and $99 a month for 50/5Mbps service.
