When you use an unlocked phone on a carrier overseas the phone and texting will work right off the bat, but internet and picture messaging won't. To get them to work (or to get them to work well), you need to input the appropriate APN settings into the device so it knows how to access the internet.
Enter the information for each field for the carrier you are using from the list of settings below.
Wait 2 mins and then try to access a website from your internet browser.
Did you check if your phone's frequencies are compatible with the new carrier you want to use? Check the 3G/4G frequency below for the carrier and then head to our Device Specs section to see if your device has those frequencies enabled. If not, you might not get the fastest speeds.
