Data Roaming Off, Still Charged

[sammyh25]

Using a Samsung S7 Edge.

I travel to World for business and always have data roaming off, unless I wish to turn it on in a World Traveller zone. I recently landed into Tehran, Iran and when the mobile picked up the local network various notifications and apps obviously had a data connection as they updated for a few seconds.

Before I had a chance to double check my settings the usual "data roaming disabled" message appeared and no further data was flowing until I accessed wifi.

There seems to have been an issue with either the mobile and/or the local network recognising that data roaming was off, and as a result I have charged £6 for 1.02 Mb of data. (29/01 at 10:19).

I'm hoping not to visit "Iran" again in the near future and whilst I have never came across this issue on my travels before I'd be greatful if someone could come up with a reason as to why this issue occurred in the first place and possibly advise how I can get the charges refunded.

regards.

It sounds more like an issue with the handset rather than the network. Even though you've got the data roaming option set to off. It's allowed the phone to connect to the data network. 

As you're controlling data roaming via the handset itself rather than via the network (which to be fair, we all do), I'd raise the issue with Samsung.

Otherwise this could happen again.
