O2 Unlimited On Demand – No more usage SMS notifications

Hello,

I have been experiencing a very strange issue with my O2 Unlimited On Demand tariff for almost 2 months now, and unfortunately neither email support nor the hotline has resolved it.

At first, I stopped receiving the 80% / 100% usage SMS notifications. However, sending “WEITER” manually to 80112 was still working.

Important detail:

• I can send and receive SMS normally

• I receive replies from 80112

• If I send “WEITER”, I receive responses

• Even random test SMS to 80112 receive replies

So this clearly proves that SMS communication itself is working correctly on my device.

The problem only affects the specific usage notification SMS.

So the issue is definitely not caused by my iPhone.

The last usage notification SMS I received was around March 11.

Has anyone else experienced this issue with Unlimited On Demand?
And was it eventually fixed by O2 technical support?
