Hi, 

please explain to me why you use 11049…?

Intern. number is 0049…..

Maybe there is the mistake.

Hello @JeTiNiMa ,

welcome to the o2 Community .

There is no block for incoming calls from outside Germany , I’d also expect that the issue here with the number just like witti is also suspecting.

Kind regards, Sven

I first gave number +49… Didn’t work.

Then I read on internet the following: 

 Mobile codes:

I see typo in my fist message I gave them 01149, not 110. Again didn’t work. Not sure what else could be the problem.

Can it be something in my phone settings then? 

49

The prefix (represented by +)  will depend on the country the call is being made from. Many use 00 but not all.

From the USA it is 011.

@JeTiNiMa Unless you have an App which is blocking incoming calls from abroad, it is more likely that the problem is with the service the caller is using.

Hi @JeTiNiMa were your friends able to call you yet?
Sometimes people dial the 0 for the provider number, Please use this format: 0114917*******
