For anyone considering moving to Vector, whilst working well in the UK, DO NOT expect it to work abroad like any other network provider. It simply has never worked for me on my travels.

 

Thanks to auto-correct my title is wrong... It should read VECTONE sims

 

They are similar to gif gaf or Lebara and their packages are impressive such as unlimited calls including international ones, SMS and data for around £10/month which works really well in the UK but despite advertising international roaming as per European regulations their SIM does not seem to connect with many or any European providers. So if you plan a trip in Ireland, France or any other european country, you are best advised to get another pay as you go sim card like Three for your trip. The only place I got my Vectone SIM to work was in Germany.

 

I have contacted their customer support on every occasion but they are not really any use on this issue, I don't think they encounter issues relating to usage abroad very often. So the advice is same every time: set SIM to outside UK, take SIM out of phone and restart the phone. This has never worked yet, I even had a replacement SIM sent without success... Luckily my phone is a twin SIM and I use my alternative during my trips, but I felt it was important to warn other potential users of this issue before signing up to VECTONE if they intend to use it on their travels.
I am not a technician but this issue seems to me as relating to a network partnership in the international roaming world?
