I searched for "General Mobile", and kept landing on a provider of mobile devices in Turkey. (Good for my language lesson of the day, though!)
The $9/mo plan requires purchasing a 3-month plan. (Discount for purchasing multiple months.)
I got the same page, written in Turkish, when I Googled it, too! Finally tried the link on the Prepaid Compare website and got to their no-translation-required home page (thank you, Dennis).
However, I didn't look at all the tabs on the "plans" page, so I missed the 3-month discount. Thanks for the redirect.
One more thing to consider: We know that Tello's customer service is exemplary, but I don't have any idea how good it would be with Gen Mobile. Since they both run on Sprint only (no roaming), and Tello is cheaper even without a multi-month discount, I don't see any compelling reason to switch from Tello... but of course, as always, YMMV.
