This article will help answer the question: Which unlocked iPhone SE should I buy for my carrier network? We’ll discuss the model differences, carrier compatibility and help you choose the right iPhone SE for Verizon, AT&T, T-Mobile, Sprint or your favorite MVNO.

Unlocked iPhone SE: A1662 vs A1723

The A1662 is fully compatible with Verizon, AT&T, T-Mobile and most US MVNOs. The A1723 is preferred for Sprint and international carriers.

A1662 models have support for all the LTE bands used by Verizon, AT&T and T-Mobile. This includes Band 13, used by Verizon, and Band 29, used by AT&T; the A1723 is lacking these. Both the A1662 and A1723 support Band 12, used by T-Mobile, which the iPhone 5S was lacking.

The A1723 has all the bands used by Sprint, including the high-speed “Spark” Band 41. The A1662 does not include Band 41 support; it will work with Sprint on LTE, just not optimally.

A1723 models also have some international roaming bands that are missing from the A1662, such as Band 7, used in Canada and other countries. The A1662 will get LTE signal globally, just not with maximum speeds.
