ZenSim does not offer a true unlimited highโspeed data plan for Turkey. Their soโcalled โUnlimitedโ plans actually provide only 3โฏGB of data per day; once that daily limit is reached, the speed is throttled (though no specific reduced speed is listed).
Travelers who need more data have alternative fixedโdata options. For example, a 20โฏGB plan can be purchased for 10 days atโฏ$26.00 USD or for 30 days atโฏ$29.00 USD, and a 10โฏGB plan is available for 10 days atโฏ$18.00 USD. These fixed plans give a larger total data allowance and may be more economical for heavy data users.
