Mobile Data Not Working In Europe

[#1]

The mobile data for my sim is not working in Europe.  So far I have experienced this in Germany, France, and Spain.  In each country have tried the following:

• Putting the phone into flight mode. Switching off and remove the sim card for 10 minutes. Re-inserting the sim card and turn the phone back on.  Turning off flight mode.  Waiting for 5 to 10 minutes to see if the connection is working.
• Manually connecting to a network (Orange, Movistar, YOIGO, Vodafone ES).
• Resetting network settings via General > Reset > Reset Network Settings.
• Trying the sim in another mobile device.

Calling and texting is fine, but each time no success with getting any data.

Does anyone have any other suggestions for a fix, or is it just time to switch mobile providers?  Thanks for any help!

I also had a similar problem in France, all I could get was 3g, others have been having the same problems and it does not appear PlusNet have fixed this, I have now left PlusNet as from my conversations with tech support I have no confidence that this will be resolved soon.

This is good to know, thank you.  Time to leave PlusNet I think.
