New Nokia 3310 may not work with your carrier
By Mihăiță Bamburic
Smartphones work on a wide range of cellular frequencies to support various networks and technologies. As a result, you can take a smartphone from the US to Europe, throw in a local SIM, and use it to make calls, send texts, and access the Internet. Sure, it may not work as you expect with every carrier, but it will get the job done on a basic level at least. Dumb phones, on the other hand, are much more limited.
