Step 1
Go to the package 's page on the Turkcell's website.
You can find all packages using the query: "Faturasız Mobil Wifi Fırsat" site:turkcell.com.tr
E.g.: «Faturasız Mobil Wifi Fırsat 200 GB».
You will see the package's price.
Step 2
Top up your data line balance up to the package's price.
I do it via the Turkcell's mobile application.
Step 3
Look again at the package 's page on the Turkcell's website.
You will see which SMS you need to send to buy the package.
For the 200 GB package, you need to send the Mobil 200GB
message to the 2200
number.
Step 4
I send the required SMS via my router's web inerface.
My router is TP-Link Archer MR600 V3.
It serves a web interface at the http://192.168.1.1
URL.
