A:AnswerThis particular phone is locked to AT&T's network. You can get it to work in Switzerland but you would have to get the carrier to give you the unlock code. I have done this while traveling abroad to use my phone with local cell service providers.
A:AnswerAs far as I know the major difference is the screen size. I believe the Note 2, which I have has the biggest cell phone screen available today.
A:AnswerIf you buy the AT&T or T-Mobile version it would be a GSM Version, Verizon and Sprint's Versions are CDMA versions so they are not compatible. However, all these phones are locked to the carrier that they are branded to -AT&T to AT&T, Sprint to Sprint etc. When you buy a phone you can unlocked even if you sign a two year agreement. The downside to signing the agreement is that you are locked with that carrier for 2 years and if you terminated the contract you pay an early Termination Fee. Depending on the price of the phone and the carrier's ETF fee and when you break the contract it might be cheaper than buying a phone without a contract. Compare the costs and you might see in the long run even breaking a contract might be cheaper.
A:AnswerIf you purchase an AT&T branded or T-Mobile branded version of the Galaxy S4 it will be carrier locked to that carrier. You can call the carrier and ask for the unlock code so that it may be used on any gsm carrier(usually you would do this if you were planning on traveling overseas where the roaming charges would be large and you would buy a local sim card for the duration of your trip). They DO NOT have to give you the unlock code. Sometimes you may have to try three or four times to get it from them. There are other options but most will involve paying anywhere from 20 to 35 dollars to have the phone unlocked.
A:AnswerYes, but expensive everywhere you go. I have mine that is extremely well taken care of, no scratch, no dent, never dropped whatsoever, extremely clean in and out with all paper work including the untouched box, materials, headphones etc. it came with. Also, my Galaxy S4 phone finally is unlocked from AT&T that can be used with any sim card anywhere.
