No I have never set any kind of lock.

Hi @Bilal035, 

welcome to our English Community. 

fritz04 already gave you good suggestions. Thanks a lot for that. 

According to our website https://www.o2-freikarte.de/prepaid-ausland/ you see that receiving SMS in Pakistan is for free. 

I confirm that receiving SMS is not blocked. But be careful with using internet or calling or writing SMS. All of this is not for free. 

The best thing to do is to block internet for abroad in your device. 

I hope I could help you with these suggestions. 

Loving greetings,

Tobias

Turn off your mailbox with ##002# and press the green dialing button.

Turn of data roaming.

Incoming calls are not free.

Change the APN from pinternet.interkom.de or internet rto something else, i. e. ppppp

If you have entered your bank details in Mein o2 for automatic top-up, remove all markers and confirm the change.

Thanks to @tearsbeforecrying for mentioning these safety measures. 

Loving greetings,

Tobias
