    Worked as expected

    This SIM worked as expected. Overall I had mostly 4G internet speed and more than enough to do what I needed and wanted. Also the service from Online Abroad was good. Happy customer, will buy again.

    Thanks guys for this SIM. I was able to continue doing business like home without having to worry about roaming charges. More than enough data also and although I never thought I would use it, the international calls were handy as well.

    Will order again in the future

    Bad signal

    Posted by DJ on 2nd Nov 2015

    I've used this SIM-card twice before without any problems, but this time it didn't work well. The attached APN file for iPhone was an outdated one, and made internet connection very very slow! I called H20 and got the right APN file, but it only helped a little bit. Maybe it just doesn't well work on iOS8? Calling/texting was no problem.

    [Online Abroad reply]
    Hi DJ. Could you contact us with some more details? It should work without problems with iOS8 as well so there might be something else that needs attention. Good to hear that you contacted the technical engineers of H2O in the USA but we would like to make sure no additional attention is needed.
