I am travelling in the States at the moment. Upon arrival I immediately bought a local MicroSIM card from Simple Mobile. However, the connection speed at times is intolerably slow even when I am in the San Francisco city center. A google page can take 3-4 minutes to open. Simple Mobile uses a different technology called Edge (denoted as E on my iPad instead of the 3g that I am used to). I am not familiar with this.
I went a t-mobie outlet and asked them for advice. I was told that it is possible that my iPad is locked to New Zealand and using it on a US SIM and plan would mean slow connection, so switching to a t-mobile sim is probably not going to help much. Is this true? Or is it just Simple Mobile's problem? I thought I was pretty familiar with iOS devices. I have heard of unlocking phones, but iPads. Really?
