I just received a bill for close to 200 euros. I don’t use my O2 sim as I have my work sim in my phone. I have forwarded all voice calls from my O2 number to my work number. My contact includes free calls to all German mobile and land lines. So why am I being charged for this ? I’ve just gone back over the last 3 months and I have been charged for it there too.
