Would it also be rather strange to print that on the invoice? Doesn’t make any sense either. As far as I know, you only receive a text message from the operator informing you of this. In extreme cases, they will call you. At Swisscom, over 100GB shouldn’t be a problem, although there are no figures as to when exactly this fair use policy applies.
You can use the QCI value to find out the traffic priority. To do this you need a rooted Snapdragon Android device with the Network Signal Guru app.
Then find out the QCI value of the Internet APN in Network Signal Guru.
The higher the QCI value, the lower the priority.
Most often QCIs between 5 and 9 are used. 5 is used for IMS (VoLTE), the rest for normal data traffic.
Example: A prepaid SIM from the MVNO Mucho Mobile (Swisscom network) has a QCI value of 7.

According to the English language Wikipedia page:
https://en.wikipedia.org/wiki/QoS_Class_Identifier
and the document ETSI TS 23.203 version 17.2.0, chapter 6.1.7.2:
https://portal.etsi.org/webapp/workprogram/Report_WorkItem.asp?WKI_ID=64692
QCI:=9 is the correct QCI rating for all data transmissions from non-time critical services with high packet loss rate requirements. So all 0815 applications from private customers should be processed over the air interfaces with QCI:=9. By 0815 applications from private customers I mean:
- Play video
- Listen to internet radio
- Surfing the Internet (via web browser)
- Sending and receiving emails
- Chat (Whatsapp and so on)
A packet loss rate < 1E-6 is a mandatory basic requirement for fast data transmission! See:
[https://community.swisscom.ch/t5/Archiv-Internet/IB3-erreach-nur-2-4-gbit-down-up-anstatt-10-gbit-8-2gbit-die/m-p/680968#M102795 ] (https://community.swisscom.ch/t5/Archiv-Internet/IB3-erreach-nur-2-4-gbit-down-up-anstatt-10-gbit-8-2gbit-die/m-p/680968#M102795 )
Since 0815 applications are not time-critical, the “Packet Delay Budget” may be > 100 ms.
According to the information in the Wikipedia page:
[https://de.wikipedia.org/wiki/Reichweit\_(radio technology)](https://de.wikipedia.org/wiki/Reichweit_(radio technology))
A bit error rate of 0.1% (BER = 1E-3) is sufficient for voice transmission. It is also known that voice telephony can tolerate a delay of a maximum of 100 milliseconds, so the “Packet Delay Budget” should be < 101 ms for any voice telephony over the mobile network. Accordingly, voice telephony (VoLTE + VoNR) should be carried out with the classification QCI:=1 or QCI:=7.
The difference between QCI:=1 and QCI:=7 is the “Priority Level” and the packet loss rate. In overload situations, voice telephony with QCI:=1 has priority over voice telephony with QCI:=7. The influence of the bit error rate or packet loss rate on the voice quality of voice telephony was discussed in detail under:
https://community.swisscom.ch/t5/Mobile/VoLTE/m-p/755519#M11696
shown.
A mobile phone antenna should logically first send the signaling of telephone calls on the air interface (QCI:=5 => Priority Level 1), then transmit the voice data of voice telephony (QCI:=1 or QCI:=7 => Priority Level 2 to 7) and At the very end, distribute the remaining transmission capacity of the air interface to the 0815 applications (QCI:=9 => Priority Level 9).
\=> I do not know and cannot view the QCI classification of voice telephony at Swisscom. So I don’t know whether Swisscom handles voice telephony via QCI:=1 or QCI:=7.
Swisscom could use QCI:=8 for “premium customers”. For example:
- QCI:=8 for 0815 applications from “Premium” customers (Priority Level 8)
- QCI:=9 for 0815 applications from “Low Budget” customers (Priority Level 9)
This means that in an overload situation, the data packets of “premium” customers would be given preferential treatment.
\=> The QCI classification of the 0815 applications at Swisscom and Wingo is not known to me and cannot be viewed.
I’m not a cell phone engineer. I suspect that there are much more complex mechanisms in today’s mobile network that regulate the time slot allocation. On the topic of “time slot allocation” see also:

@dxbruelhart Which subscription exactly?
Swisscom Blue Mobile L
Logically, there is prioritisation between the premium providers and the low-cost brands. So you have a reduced bandwidth with Wingo at peak times compared to Swisscom. Just as with the low-cost brands from Sunrise (Lebara, Yallo and Swype) you have a reduced bandwidth at peak times compared to Sunrise. However, it should be noted that with Wingo you have a higher bandwidth and significantly better network coverage than with the low-cost brands from Sunrise.
