Does the iPhone 5 support 4G LTE network?

Hi Brendan_0027,

Welcome to Apple Support Communities. We understand that you have a question about the 4G LTE network for your iPhone 5. We'd like to help.

According to this resource, your iPhone 5 can use LTE but using 4G may be best answered by your wireless carrier:

About the LTE options on your iPhone

The cellular-data options on your iPhone might vary based on your carrier's network.

If your carrier supports VoLTE

On your iPhone, go to Settings > Cellular > Cellular Data Options and tap Enable LTE or Settings > Mobile Data and tap Enable LTE. If your carrier supports Voice over LTE (VoLTE), you'll see these options:

* Off: Turns off LTE

* Voice & Data: Allows voice calls and cellular-data use over LTE 

* Data Only: Allows cellular-data use, but not voice calls over LTE

If your carrier doesn't support VoLTE

If your carrier doesn't support VoLTE and is a GSM carrier, you'll see one of these options:

* LTE or 4G: Allows cellular-data use over the LTE or 4G network when available.

* 3G: Allows cellular-data use over the 3G network when available.

* 2G: Allows cellular-data use over the 2G network when available.

Depending on the wireless carrier, 4G can indicate either a UMTS or LTE connection. If your carrier doesn't support VoLTE and is a CDMA carrier, you'll only see an option to Enable LTE. This allows cellular-data use over the LTE network when available.
