Using frequencycheck.com, you can find your carrier under your country to see which bands are supported by them. However, keep in mind that not all of these bands may be available in your area.

To find out which LTE bands are available from cell towers in your area, you can look at cellmapper.net. Additionally, if you call your carrier they may tell you which LTE bands are available in your area but they also may not divulge this information.

Note that some carriers do not allow devices on their networks unless devices are approved by themselves.
