A got my SIII in 2013 and plan to upgrade it to the S5 as soon as I can.
When I got it, I called tech support about using the phone while on a European trip, I was told that the phone was "World Ready" and just needed to switch SIM's. Well, that was half-true. The phone worked with a new SIM card but only in voice mode (I didn't try SMS) but I could not get Data mode to work and that was the main reason to take it in the trip. The phone would not let me change the APN.
I have a couple of questions
- Before I upgrade to the S5, can the APN lock be unlocked temporarily for a trip outside the US?
- Once I upgrade the S5, the SIII will be used for trips outside the US. Can it be completely APN unlocked?
Thanks
