    Recently I was abroad and despite my roaming being switched on I wasn’t able to get data 🙁

    What could be the problem?

      romain is usually for voice call only, by default most phones have the data roaming option switched off, you might probably want to check that… be advised that romaing data can be very expensive


    Hello, I’m french and I bought a SIM card ( so I have an English number, the problem is that I can receive calls and nothing else (I’m in Ireland right now ) and impossible on my LG KU990 to configure if you could help me, thanks

      did you try setting up the APN shown on the page?

      Seems to be a common Three problem on Android. Nothing I did on a Samsung Galaxy S7 Edge in USA would persuade the SIM to access data. Put the same SIM in an iPhone and it immediately worked fine.

    Exactly same problem in US with Samsung Note 8 with roaming turned on. Roaming worked fine in Brazil and Chile but here, with the same APN, no data, ever. SMS is fine. Very baffling. Hope it comes right when I get to Iceland!
