As a result, unlocking a device without the carrier's permission is now illegal. Most of the major operators, including AT&T, say they will unlock a phone once it's paid off. And all the legislation I've seen proposed to solve this problem also suggests consumers should be able to unlock their phones once they're paid in full. But no one seems to see the practical problem this presents for people who travel. It seems unfair and anticompetitive to refuse a wireless subscriber the option of using a dramatically less expensive alternative to his carrier's international roaming plan.
As for your second question: Will the Galaxy S4 operate on a 4G wireless network in Spain? It depends on what you consider to be "4G." There are no carriers in Spain offering 4G LTE right now, LTE is considered the fastest 4G wireless technology available today, While European carriers plan to deploy LTE in the future, right now most support HSPA+ technology, This network iphone 8 olixar x-ranger survival case - black reviews technology is capable of offering network speeds that can be similar to an LTE service, This is why AT&T and T-Mobile also call this service "4G." AT&T, which has deployed LTE, also has HSPA+ technology in its network..
For the most part, when people talk about 4G, they mean LTE. So the short answer to your question is a simple no. You will not get 4G service in Europe. But you may be able to get similarly fast speeds. Even if European carriers offered LTE today, the Galaxy S4 would still be unable to roam onto those networks. Why? The radio frequencies that U.S. carriers are using for LTE service are not the same as the frequencies carriers in Europe plan to use. As a result, a phone designed for AT&T's 4G LTE network will not be able to access another LTE network unless the device includes the same spectrum support.
Since AT&T won't unlock your new Galaxy S4 unless you pay full price for it, what should you do? First of all, I don't think it's worth it to buy the Galaxy S4 at full price just so you can use it abroad with a foreign SIM, My advice is before you upgrade to the Galaxy S4, get your old smartphone unlocked, If you are out of contract, which it sounds like you are, and you're a customer in good standing with AT&T, this should not be a problem, I'd use the older, unlocked smartphone while in Spain instead of the new Galaxy S4, This way you can put a Spanish SIM card in your unlocked phone and you'll save yourself some more money, If you still want to buy the Galaxy S4 before you leave, go ahead, You can always put the device on airplane mode and use all the Internet-enabled features and apps when you are in a iphone 8 olixar x-ranger survival case - black reviews Wi-Fi hot spot..
I hope this advice was helpful. Good luck with your summer semester abroad. Dear Maggie, Almost three years ago, I bought an iPhone 3GS with a new two-year contract from AT&T. It came with a $30 unlimited data plan. My two-year agreement ended in June of 2012. I bought the new iPhone 5 in October and kept my old unlimited data plan. I gave my old iPhone to a family member, and I added her to my plan for an additional $9.99 per month. She just put her old SIM card from her flip phone into my old iPhone. She still only uses her phone for voice calls and text messaging. She does not use any data, unless she is in a Wi-Fi hot spot.
