Can anyone at IdMobile please explain why coverage in Germany seems to be non-existent? I was on a road trip recently (Italy/Switzerland/Germany/France/UK) and was obtain coverage successfully until I entered Germany. Throughout the German portion of my trip there was absolutely no coverage available (yes, I tried changing to all available providers), then as soon as I entered France it all started working again.

Hi ​@JonathanL,

 

Thanks for taking the time to share your experience, this is really helpful for other customers travelling abroad.

 

You’re right that in some cases, settings like a bill cap can affect how your device connects to partner networks while roaming. Germany can occasionally behave differently depending on the network your phone attempts to connect to, which may explain why your experience there wasn’t the same as in Italy, Switzerland, or France.

 

Setting the bill cap to £0 can help ensure there are no restrictions on certain chargeable services, which may impact connectivity in specific scenarios. That said, roaming should generally work without needing to adjust this, so we appreciate you highlighting it.

 

It’s great that you’ll be testing this again on your next trip, please do let us know how you get on, as your feedback can really help others in the community.

 

Safe travels for your trip in May!

 

Thanks,

Hi ​@JonathanL 
 

If you experienced no service while in Germany, this could be due to a temporary network or device issue, as sometimes phones take time to register on the local partner network, especially with eSIMs or after switching networks manually.

 

What you can do to help ensure service:

  1. Make sure Data Roaming is enabled, and your network selection is set to automatic.
  2. Restart your handset once you enter Germany this often helps the phone register correctly on the local network.
  3. Ensure your SIM (physical or eSIM) is active and correctly provisioned.

We’ve also set your bill cap to £0 to ensure no unexpected charges while roaming.

If you continue to experience issues on your next trip, please contact us and we’ll work with you to investigate and ensure your service works as expected.

Hi Owethu, and thanks for your response.

Unfortunately, however, the steps you mention did not and would not work. Logically, if the connection was working when I was in Switzerland, not working at all in Germany and then started working again immediately I entered France, the problem cannot be with the Data Roaming setting. Network selection was set to Automatic (though I tried selecting all available providers individually as well, to no avail) and of course I also tried restsrting my device, several times in fact.

Secondly, the eSim was working in Switzerland (and later in France) but not in Germany. So logically there was no problem with the eSim either.

From my perspective this points to a problem with IdMobile’s arrangements in Germany. Can you confirm that there are such arrangements in place to allow your customers to roam in Germany?

Hi ​@JonathanL 

 

Thank you for the information provided.

 

iD Mobile has roaming agreements in Germany, as it is one of our 50 EU roaming destinations. Our network partners there are Telekom (formerly T-Mobile) and O2.

Could you please confirm if you were connected to either of these networks while in Germany?

Hi Michael Z

Yes, I definitely tried to connect to both Telekom and O2-de, unsuccessfully.

I want to summarise the discussions I had with IdMobile over this issue for the benefit of other customers. According to them I would have to set the bill cap on my account to zero in order to connect automatically to the partnering networks in Germany. Note that I did not need to do this for the other countries visited on my trip (Italy, Switzerland and France), so it seems that Germany is a special case in this regard.

 

i will be travelling through Germany again in early May, and I will check out this proposed solution. I hope that other IdMobile customers find this information useful.
