Mobile in Switzerland

[msmobile]

My wife and I arrived in Switzerland today 

neither of us can make or receive network calls 

we have date and can receive texts inc from BT telling us we can make calls as usual 

we have been here many times before on the same mobile plan without hitch

Notwithstanding the fact that you’ve visited Switzerland many times before, but you have made sure that roaming is enabled on your handsets?

Yes
We crossed the border to Italy for a day and our phones were fine
Then back to Switzerland and same problem~
My wife could make occasional calls
I couldn't make or receive calls
Swisscom told us they switched off 3G this year and this might be something to do with the problem, but not obvious since our phones were showing 4G and 5G

Hello @msmobile. 

Thanks for confirming. 

Have you tried selecting another available network?

When you arrived back in Switzerland did you reboot your phone?

Speak soon, 

Katie

Thank you

Yes we tried Salt and Sunrise, the other 2 Swiss networks. The reception was very poor -  1 bar - whereas in the past they were fully accessible, and if we tried to make a call on these networks they immediately defaulted to no reception available 

rebooted the phones lots of times

That's strange @msmobile.

I'm unsure what could be causing this. 

Do you have access to another working phone?

Our technical care team can be contacted by calling +44 150 174 7714.

Thank you
We're back in the UK now
I dialled 150 yesterday and spoke to someone, but they had no useful suggestions
We travel to Switzerland regularly though and so if this recurs we'll have to change mobile providers

Maybe BT have reduced their roaming agreements? Several countries now there is only one network that will work with BT, and this might not be one that provides universal coverage.

So I have been experiencing problems making calls in Denmark. Calling another BT mobile on TDC network results in one ring tone, followed by silence. The call continues according to the phone timer, but the called mobile hasn’t registered an incoming call or missed call at all.

Yesterday it rang properly and got through after three attempts. Today didn’t work after 4 attempts so rebooted the phone. It then worked the next time.

So unknown whether it is a problem with iPhones, TDC or BTs ‘roam like home’ solution, but definitely flakey.

That's interesting - I think we had some failed call attempts like that too, but re-booting the phone didn't help

So the common features are iphone + BT roam like home + the other country has shut off its 3G network (Switzerland this year, Denmark a few years ago)
