All Pakistan cellular providers claim they prepaid SIM is prepaid SIMS are preactivated for International Roaming.
I carried three SIMS with me. I have a Jazz , Ufone sims.
When I landed at Istanbul airport. Only Ufone and Jazz were showing signals ‘R’.
Before living for Munich, I called the the helpline of all the cellular providers. Asked them to confirm if their prepaid SIM are prepaid SIMS are prepaid activated.
I only found signals in Jazz and Ufone SIMS.
I will like give a helpful tips to travellers who are visiting Turkey or landing at Istanbul airport for Transfer.
When you land at the Istanbul airport, connect to Vodafone network this way.
Go to SIM card and Mobile Network and touch on this . It will take you to this screen.
First change your default SIM card settings. Change Data , voice and SMS to Ufone.
Touch on Ufone SIM card. It will take you to this screen.
Activate Mobile data and Roaming. They will turn blue on Android. Then chose ‘Choose network’.
It will take you to this screen.
Turn off the automatic network and search the networks available. Select the Vodafone network. It will register the network after few seconds.
Then you will start using the internet.
Activate Ufone Turkey Package This way.
When you land at Munich Airport. Dial #506# again and activate the International Roam Again. I did because roaming did not start automatically.
You have balance in Ufone Account.
Zong SIM did not show any signals.
Ufone Helpline will tell you to connect to Telefonica. But this service will not show. Though it send me sms that you are using Telefonica.
